Application Of A New Database Management System

Application Of A New Database Management System
When selecting a new database management system, determine if the vendor offers auditing,
reporting and data management tools. In addition, the software should provide application level
security and interface to the organization 's corporate–wide procedures for granting access to
systems. For example, authentication should allow a secure protocol, such as Secure Sockets Layer
(SSL). In addition, data may need to be encrypted to ensure additional protection. Application
security gateways and database firewalls understand the application and track user access. Deep
packet inspection examines each packet going over the network to the database server to determine
the type of access being attempted. Application security gateways can provide ... Show more content

To discover and document existing organizational policies, the solution selected should be able to
automate a process of report production that covers such topics as planning and organizing for
database compliance, certification and control of database activities, risk assessment, and
investigation and disclosure of any exceptions. Having access to report templates that were built to
address SOX implementations creates an ideal situation, since such templates do not require a great
deal of setup but still have the flexibility to be customized to company needs. All database requests
must be able to be logged and a full audit trail should be easily and automatically extractable from
this information. This audit trail needs to contain such information as which data was accessed, by
whom, when, how, and from where. The exportable information can be maintained for as many
years as necessary and submitted to the proper authorities as required. Automated scheduling of
SOX workflows and audit tasks and dissemination of relevant information to responsible parties
across the organization are also great time savers, helping to increase audit process efficiency.
When potential anomalies arise, the response must be instantaneous. Automatic alerts and access

Database Analysis : Database Management System Essay
Choosing A Database
Everyday the world progressively moves towards a digital future, and the use of physical data
storage, such as files in filing cabinets, are becoming obsolete. Most companies store their
information into databases to easily manage and share their data within the organization. A database
management system (DBMS) is needed to to create, use and maintain databases for the efficient
storage and retrieval of data.
Why Choose a Database?
Before one can begin to choose a database, it is first important to understand the goals and purposes
of the organization and their database needs. Databases are not a one size fits all, and need to be
thoroughly researched before moving forward.
To understand what an organization's database requirements may be, it is vital to discern what uses
can be had from a database. Databases are key in a business operation, they allow for the quick
access to company data, and help to quickly sort and deliver information when needed. A few
examples of the functions a database can provide for a business is the ability to track customers,
their inventory, and even employees.
Being able to manage customers in a database is one of the biggest assets a company can gain when
transitioning to a database. A customer is the 'lifeblood' of a business and using a database can help
to keep the customer's contact details, previous orders, and any other pertinent data that may apply.
Another benefit to keeping customers in a database is the

Case study
Exclusive Summary
The terms data and Internet are connected with one device and its call "Computer". Now a day's
people are taking more interest regarding data and related terms. In general database means a
collection of information that is organized so that it can easily be managed, access and update. In
General, databases can be classified according to types of content: bibliographic, full–text, numeric,
and pictures. Whereas, Internet play an important role in today's world. The meaning of INTERNET
means an electronic communications network that connects computer networks and organizational
computer facilities around the world. Internet is connected with two different part called intra and
net. Moreover, it includes business, instructive, administrative, and other networks, all of which
utilize the same arrangement of interchanges conventions.

Database Security Databases are used to store different types of information, from data on an e–mail
account to important data of government agencies. The security of the database inherits the same
difficulties of security facing the information, which is to ensure the integrity, availability and
confidentiality. Database management system must provide mechanisms that will assist in this task.
SQL databases implement mechanisms that restrict or enable access to data according to profiles or
roles provided by the administrator. (Mittal, 2009). The "GRANT" command grants specific
privileges to an object (table, view, sequence, database, function, procedural, schema, or table space
language) for one or more users or groups of users. The concern with the creation and maintenance
of secure environments is one of the main concerns of the network administrator, operating systems
and databases. Research shows that most of the attacks, theft of information and access non –
authorized are carried out by people belonging to the organization. For this reason, these
professionals strive to both create and use tools in order to eliminate unauthorized access or reduce
the opportunities of success of attempts to attack either internal or external. Information systems
access controls must certify that all the shortcuts to the system happen exclusively according to
modalities and pre–scheduled rules observed by protection directives/policies (Ben Natan, 205).
Generally, security

Database Management System Software ( Dbms )
Introduction Database management system software (DBMS) is the software that can operate on the
front and back end of an organization's database. As do the database requirements of an organization
differ, so do the types of DBMS software. The type of DBMS software required can often be
narrowed down to the organization's size and industry (Mohamed 2016). Currently, the top three
DBMSs are Oracle, MySQL, and Microsoft SQL Server ("Microsoft SQL Server vs. MySQL vs.
Oracle Comparison" 2016). Each having its own forte; however, in this assessment, only MySQL
and Microsoft SQL Server (MS SQL Server) will by compared and contrasted to one another in the
aspects of an organization's needs, the hardware requirements, and the database ... Show more

MySQL also has a low total cost of ownership, in part, due to its diverse platform capabilities, free
use for simple users, and in–house operations. As a result of MySQL's broad compatibility and
ability to perform typical database needs, it is an appropriate selection for organizations looking for
a cost effective DBMS for lightweight to medium weight database requirements. MySQL has
different editions to meet the database needs of organizations. The different editions are as follows:
MySQL Community, Standard, Enterprise, and Cluster Carrier Grade ("MySQL :: MySQL Editions"
2016). The free MySQL Community Edition has the least features, has very limited security, and
only limited support on the forums. Organizations seeking support might choose MySQL Standard
Edition for an annual subscription at $2,000, which offers 24/7 support but also has limited security
and is unable to offer security, backup capabilities, and scalability. If security is a concern for an
organization, MySQL Enterprise Edition offers the previous editions feature in addition to security,
database backup, scalability, and an audit program for a yearly subscription of $5,000. For
organizations operating at multiple locations with high automation needs, MySQL Cluster Carrier
Grade Edition can automatically support the organization and has automated repair function to
maintain continuity for an annual subscription of $10,000. The

Annotated Bibliography On Database Management Systems
The ability to store information has always been important for our survival. In the beginning,
information used to be shared by word of mouth. Then, with the invention of writing, data slowly
started to be stored in books kept in libraries, sorted in specific order that made them easily
accessible. Finally, the invention of the computers led to the evolution of databases.
Databases are important, because thanks to them humans are able to store and later on retrieve
information. The way in which databases arise is very simple. It all begins as a list in a word–
processing system. As the size of the list increases, the data starts to appear inconsistent. If this
occurs, Database Management Systems come to help, due to the fact they can store a large amount
of information in a number of tables linked to each other. Programs such as Access are able to add
new data to a database or make changes to already existing data from the database; they are even
able to delete information.
These features assist people in analyzing and categorizing information in the following way:
Tables lie in the core of any given database. Thanks to them, the possibility of redundancy is greatly
reduced. A database can consist of a number of different tables which enables the researcher to break
information down into smaller (and easier to analyse) pieces. Just like spread sheets, they consist of
rows (also called records) and columns (fields). By using records, researchers are able to combine

Fundamentals of Database Management System
Before we talk about Fundamentals of database management system, we need to know what is a
'Data'. Data is a something which has an implicit meaning and that can be deduced to new facts
which can be recorded too.
Then we have to know what is a 'Database'. Database is known as organized, structured and
centralized set of data collection which are stored in a computer system. That can be managed,
updated and accessed.
Now we have to know what is 'Database Management System'. Database Management System is a
software package for store, manipulate, retrieve, update, maintain and data analyze in database.

It was a first attempt of using data into databases, same time as the hierarchical data model were
developing. In the network data model data is represented as collections of records and relationships
are represented by sets. The most popular network DBMS is computer associates IDMS/R. network
data model were used for large databases. In network model files are related as owners and members
like in hierarchical model. But member file can have more than one owner in network data model.

The process of restoring the backup of log files and database on a primary server and restoring them
to a standby server is called Log shipping.
21. Local temporary tables are visible only to their creators during the same connection to an
instance of SQL Server as when the tables were first created or referenced. Local temporary tables
are deleted after the user disconnects from the instance of SQL Server. Global temporary tables are
visible to any user and on any connection after they are created, and are deleted when all users that
are referencing the table disconnect from the instance of SQL Server.
22. Scheduled jobs are automated pieces of work that can be performed at a customized date and
time on a recurring schedule. Scheduled tasks are created using SQL server, which enables the SQL
commands to be executed automatically at regularly timed intervals.
23. A Heap Table is a table that does not have cluster or a non–cluster indices. Multiple non–
clustered indices can be created on tables that are stored as a Heap. When they are stored in a Heap
they are not ordered in any specific way.

Week 1: Overview of Information and Database Management Systems 6411–2 Main Post
The Database Management System of a healthcare organization is an application to perform
administrative tasks on a database and interacts with the data stored in the databases. Years ago
information was managed by a hands–on method such as files in the file cabinet. Now, databases are
utilized by technology to drive and manage information. These "databases are an organized
collection of data typically stored in an electronic format. Databases allow input, manage, organize,
and retrieve data quickly" (Cornell, and Morris, 2015). Then Technology takes the data collected
and transforms it into information which becomes knowledge to the users. The purpose of the study
is to examine the use of the database system in nursing and to determine the benefits and challenges
of the healthcare organization to use database systems and data.
Analyze the use of database systems and data in nursing practice
Select a database system that you encounter at work or with which you are familiar.
As the introduction of the study states, "many healthcare organizations are exploring new ways to
use this data to improve health outcomes and the quality of patient care" (Laureate edu, 2015). For
instance, Methodist Hospital of Houston Texas embraces the use of database system in their
laboratory which is just one example of technology. What's helpful about using the database

Database Management Systems And Databases
Abstract:
NoSQL Databases also referred as Not only SQL databases. These NoSQL database have these days
gained much attention and reputation because of their performance and high scalability. The
advantage of NoSQL database is to store efficiently unstructured data. These days use of e–
commerce websites, social networking sites etc. has been increased. These usage made to create the
need to store the large data. Some companies have adopted NoSQL databases, as their data is
growing. Dynamo, Big table, Voldemort, Cassandra are the NoSQL databases that are used by
Amazon, Google, and LinkedIn and Facebook respectively. Facing these huge data has become
challenging for Relational Database Management Systems. Hence NoSQL database came into
existence. Mostly Relational Database Management System satisfies ACID properties, through
NoSQL database we can achieve high level of Scalability and performance. As a lot of sensitive data
is stored in NoSQL databases security issues becomes growing concerns. This Paper explains about
overview of NoSQL databases like Cassandra, mongo dB and their security features.
Introduction:
Database Management Systems has some basic requirements. They are confidentiality, integrity and
Availability. Availability means the stored data should be available when needed. These data should
be available only to the authorized entities called as Confidentiality. If that data is modified by the
authorized entities it is called as integrity. The traditional

Questions On Database Management System
1. Interpreting language:
Since the file–processing system can be built on any of the programming languages, this will be a
tedious task for other language developers to understand the actual logic behind the data storage and
build a new requirement. But Database Management System (DBMS) uses a Structured Query
Language (SQL) which will be used universally to insert, update or delete the data by all the
developers and this will act as a common language for all the developers/ end users to work with the
data.
2. Data redundancy and inconsistency.
In file processing system, many files are generated or created using different programming
languages by different developers in one particular project.
For example, let us consider the example of a Software project which consists of various teams/
developer teams.
a. Duplicate data:
In our software project example, if we have a particular person working on two technologies namely
.NET developer and as an Automation test developer, then the same person information (namely
employee id, email id, phone number) will be stored in both the files(namely .NET team file and the
Automation test developer file)
In DBMS, by using the normalization concepts on tables, we design the database in such a way that
the data is not duplicated.
b. Data Redundancy leads to higher storage and access cost.
As the same employee's data is stored in two different files, this leads to unnecessary usage of disk
space for the same employee data which will

Database Management System ( Dbms )
A database management system or DBMS is a certain type of system software, which is used for the
creation, and management of databases. A DBMS serves for multiple purposes but is mainly used to
provide users and programmers with a systematic way to retrieve, create, manage, and update data.
A DBMS serves as an interface between data and its end user, making sure that data is consistently
organized and remains easily accessible to users. DBMS's are vital to several aspects of our
technological world and are responsible for the data organization of several thriving industries in
this world including banking, airlines, wealth management, manufacturers, credit card companies,
and telecommunications. A DBMS is useful for providing a view of data that can be accessed by
multiple users, from multiple locations at one time. A DBMS can act as a filter and can limit what a
user sees and also sets limits on how that user can view data. Users and programmers are free from
having to determine where the data is physically located or on what type of storage media it resides
because the DBMS simply deals with all requests. The DBMS can give both logical and physical
data independence, which means that it can protect its users or applications from needing to know
where data is stored. Although a DBMS benefits several sectors of the world, they are by far most
beneficial in business organizations. Thousands of companies depend on accurate recordings,
updates, and tracking of their data

A database is an organized collection of data. It is the collection of tables, queries, reports, viewings,
and other objects. The data are typically organized to model aspects of reality in a way that supports
processes requiring information, such as modelling the structure of a major business such as
Walmart, and all of its data including things like their inventory, customers, and their employees. A
database management system is a computer software application that interacts with the user, other
applications, and the database itself to capture and analyze data. A general purpose database
management system is designed to allow the definition, creation, querying, update, and
administration of databases.The Database uses terms that are key for anyone to sift through the
collection of data that any company or business collects. terminology consists of keywords that will
help users select desired pieces of data. The primary key is a special relational database table
column of a collection of columns appointed to individually identify all table records. The primary
key's main features include: it cannot contain a unique value for each row of data, and it cannot
contain null values. The primary key is either an existing table column or a column that is explicitly
initiated by the database according to a defined sequence. The foreign key is a column or group of
columns in a relational database table that implements

That is the very first DBMS. Then IBM created their own database system, called IMS. That creates
for NASA's APPOLO space shuttle program. These two systems are the navigational data bases.
These database systems are not easy to use. In 1970s EDGAR CODD thought of a way to make
things a bit easier. He wrote a paper A Relational Model of Data for Large Shared Data Banks. This
concept becomes relational DBMS.
Advantages of a DBMS
There are so many advantages of using DBMS. The biggest advantage is DBMS lets end users and
application programmers' access and use the same data while managing data integrity. And data is
better maintained and protected. Data can be shared using a DBMS instead of creating new
iterations of the same data stored in new files for every new application. A central storage of data
provides by a DBMS that can be accessed by multiple users in same time in a controlled manner.
Central storage and management of data within the DBMS provides:
Data security. (DBMS provides high security. Anyone cannot access data without root's permission).
Data independence and abstraction.

Database Management System For A Company
A research database management system (RDBMS) is the most used database management system
for a company. Its roots date back to 1970, created by E.F. Codd at IBM. The database approach
involves the storage of data involving tables. Attributes of the tables involve rows, used as a record
of an entity. Columns, also attributes of the table, determine what will be recorded for that field.
Within a table one primary key will be found, this represents a unique column of the table. A table
may also have a foreign key, there can be more than one, and it identifies a primary key of another
table. Foreign keys allow for relationships between tables to be created.
The RDBMS is so widely used because of its simplicity to understand relationships between data.
The data can also be analyzed in many ways using queries, reports, etc. A database management
system covers all functions of the business and is essential for businesses to be run efficiently. Since
the introduction of this time of database management system in 1970 it has triumphed many former
types of widely used databases and fended off new types of databases to remain the most common
type. Times have changed in the information technology world since 1970 when IBM was running
the show and leading the world with improving and introducing new technology. I believe the top
five most used RDBMS used in the market today are Oracle, Microsoft SQL server, IBM DB2,
MySQL and PostgreSQL. Oracle database had its first

Description Of A Database Management System
A database is a collection of information sequenced and organized in such a way that the computer
may be able to source and access it on demand by the operator. Like any other management system,
a database management system is a collection of programs and protocols that enable the user to
enter, sequence, organize, retrieve and select data on demand. Thus, a database management system
(abbreviated as DBMS) can be defined as the cumulated system that helps the user to access and

Summary:
Database Management System in easy terms we can say that set of data organized in a relative way.
It allows data for various entries, storage and retrieval of large quantity of information and provides
ways to manage how the information is stored. There is big number of database providers and each
different database has its own strength so while choosing a particular database we need to
understand what the business requirement is and match them with what DBMS can provide us to
make our data management conveniently and easily. Oracle Database has wide range of products
and services that they offer. The current recent version of oracle database is 12c in market. it has
multi–tenant architecture and it has very good resources to make it more efficient for users to use. It
has unlimited number of database size and user can take advantage of various functions in it like

database with its correct efficiencies.
Introduction
A database is an synchronized collection of the data. It is the collection of schemes, tables, queries,
reports, views and other objects. The data is typically organized to model aspects of reality in a way
that supports processes requiring information, such as modeling the availability of rooms in hotels in
a way that supports finding a hotel with vacancies.
A database management system (DBMS) is a computer software application that interacts with the
user, other applications, and the database itself to capture and analyze data. A general–purpose
DBMS is designed to allow the definition, creation, querying, update, and administration of
databases. Well–known DBMSs

Database Management Systems Or Dbms
Database Management Systems or DBMS' are essential software's for databases that take in
information to be processed, organized, and analyzed. DBMS' play a significant role in many things
we interact with on the daily like the internet. DBMS' can be on a small scale for individual use or
on a larger scale for a company looking to keep track of all the data they collect.
Each database is custom designed for the company, or organization that will use it. Records are kept
in databases and each record is very unique in its own way having different fields for what it
pertains to. Each record has something that makes it unique that the other records don't have. Text,
number, dates, and amounts of money are all different computations for DBMS. All of this
information is separated into fields and this is how Big Data is sorted and accessible and
understandable. The data can be put in manually or sometimes it is computer assisted when it is
more efficient. For example: a program may catch on if you are doing monthly reports and create a
section for all 12 months after one is manually made.
The use of Database Management Systems can date back to 1966. The program was made by IBM
with the help of other companies for the Apollo Program. It was designed to keep track of the bill of
materials for space crafts and other things involving the trip to space. This database used a
hierarchical format which can be considered a tree like structure which is still used today. At the top
of the

Relational Database Management System
SQL Server has a reputation of being the one of the most trusted relational database management
system as it provides great security, reliability, and scalability features. But it is also quite complex
and when the size of database grows, the response time required for a query also extends. To
overcome such situations, the administrators need to perform a smooth SQL tuning which will
ensure that SQL statements will run as fast as possible. There are different aspects related to the
program and many possible options to consider if you really want to tune a SQL Server platform.
Here are some tips which the database administrators can apply to make some small changes to tune
the SQL Server and minimize the response time required for every ... Show more content on

Example,
Query A takes 1 hour to process.
Query B takes 5 minutes to process.
Query A is non–urgent query eligible to nurse–availability.
Query B is urgent query eligible to nurse–availability.
As both queries are eligible to nurse–availability, then if the Query A is being processed and in the
meantime there is a request from Query B, then Query A will be paused and Query B will be
processed.
3. Check the Index usage quite often –
Sys.dm_db_index_operational_stats() DMF is quite underutilized tool which can provide a great
information about index usage. By using this DMF tool you may be able to gather all the vital
information required to determine which index is being used and which used to be used next. It will
even let you know various things like time elapsed for processes, latching and locking.
4. Rebuilt the index after SQL server update –
It is quite normal for a business to upgrade its SQL server platform from old to a newer one. But
sometimes this upgrade makes the performance of different queries changed. Earlier any query
which used to execute in 30 seconds would now will take 15 minutes. It happens because the query
execution plan is different in each SQL Server version. Furthermore, the sequence of table nested
loops/Inner Joins are also different. Since SQL server works in live environment, so amending the
queries is quite different.

Relational Database Management System ( Rdbms )
Background
This report provides analysis and evaluation of how Relational Database Management System
(RDBMS) can be applied to improve organization and business effectiveness. The method of
analysis includes basic information of Relational Database Management System and reference of
how database management can bring positive improvement on manage small or large amount of
information in the organization. Also, include a brief information of business those are successful in
their field's thanks of the application of database system in their organizations and recommendations

Analysis
Relational Database Management System (RDBMS) is an engine/system based on the relational
model created by Edgar F. Codd in 1970. The major distinguish of this system is the ability to use
tables for data storage while maintain and enforce certain data relationship. Another aspect of this
system is that allow users to insert, update, retrieve, and delete specific content or contents storage
in the database. Also, RDBMS provides relational operator codes that enable the relationship
between two or more entities in a database (Dangerfield & Morris,1990). These system's
characteristics can be applied on business operations improving company management of small and
large amount of information from a specific department or workplace. Relational Database
Management allows monitoring all information flow from that specific department

Annotated Bibliography On Database Management System
Abstract:
There are many restrictions on the write and read operations in database management system. These
restrictions show the measurable effect on the each and every transaction in the database
management system and which are due to some specific operations. The transactions are not only
read that data from database all the time but sometime some transaction need to delete the data items
from database and create the data items into database. Such type of transactions show high impact
on concurrency control. So, we are analyzing how those transaction bias the concurrency control in
database management system.
Introduction:
The basic problem of concurrency control is sharing the data in database at a time by many numbers
of users. Due to many users accessing data at a time which causes to produce the undesirable output
or system failure even the transaction is correct. This problem may not occur due to read operations.
This problem is due to manipulating data in database such that performing creates, modify and write
operations on data items. The delete operation has capability of deleting the data items which is
similar to modify operation. And the insert operation have able to create a new data items and assign
the values if data items are not exist before staring the transaction which is similar to the create and
write operation in database.
The delete operation can be performed on when the data items exists on database. If we perform the
delete operation

Databases are fundamentally containers for data. When data for any organization needs to be stored,
databases can be used. For example, let's say a public library stores books, we could say that the
library is a database of books. But specifically, databases are computer structures that save,
organize, safeguard and produce and/or deliver data. A database platform is essentially a database
management system (DBMS) which is a computer software application that interacts with the user,
other applications, and with the database itself to capture and analyze data. A general–purpose
DBMS is designed in a way to allow the definition, creation, querying, update, and administration of
databases1. Before we dive deeper into databases and the types, we need to know the difference
between what a database is and what a DBMS is so we don't confuse ourselves.
Database is a collection of related data stored in several different tables, and linked with each other
using foreign keys. A DBMS is a Database Management System, is a piece of software that manages
databases and lets you create, edit and delete databases, their tables and their data. Examples of a
DBMS include, MySQL, MY SQL Server, Oracle, PostgreSQL, and SQLite.

Application And Utility Of Database Management Systems
Roger K. Doost, (2002) "The need for change in the way we teach accounting information systems",
Managerial Auditing Journal, Vol. 17 Iss: 5, pp.277 – 282
The article, "The need for change in the way we teach accounting information systems", by Roger
K. Doost, seeks to address the issues of how teachers and Universities are behind the power curve
when it comes to teaching the Accounting Information Systems (AIS) course. He argues that
lectures out of the textbook will no longer be beneficial if instructors do not include hands on
training going forward."The emphasis on database and database management should be
supplemented with relevant software and teaching material to make the course more meaningful and
the efforts more fruitful". (Doost, 2002). This article is to illustrate how the incorporation of
Microsoft Access into the AIS course provides an excellent demonstration into application and
utility of database management systems. In the introductory section of this article, Doost elaborates
on the many reasons why some of his fellow colleagues are having a rather difficult time teaching
the AIS course effectively. He stated that in the past, Universities employed professors' based on
their interest in the course or having experience in the AIS field. With that being said, some
professors can teach a course outside of their professional fields of study. "The ideal professor to
teach this subject matter is one who has adequate graduate work in the areas of both

Evolution Of Database Management Systems
EVOLUTION OF DBMS
1.INTRODUCTION
As technology is rapidly emerging and changing, organizations are quickly adapting to it, and with
this technology and software advancement includes database management systems. Database
management systems have become a crucial tool in every organization. It will be rather more
surprising to see a company not using DBMS in this age. As organizations emerge and grow by
years, they have numerous data sets to handle and database management systems is a software
application which helps organizations perform this mundane task easily. It collects, organizes the
databases and also stores and performs functions on the databases making it easier for users to
access. Now days, an organization wouldn't survive without data and information. The way this data
is important for an organization, to manage this data is equally important. Database management
systems has become a part of every field right from schools, libraries, medical centers, airlines,
chemical plants etcetera. With the effective use of database management systems software in
organizations, it comes with advantages and disadvantages which will be later explained in the
findings section of this paper.
The research would concentrate more on how database management system applications have
progressed since the past decade. The research objective is to study the evolution of DBMS and
learn about the emerging alternative applications for this traditional system. The positive and
negative effects

Part 1: Database Concepts
Topic 1: The Advantages of Database Management Systems
A database system would offer the innkeepers several advantages over the flat file system, including
enforced data integrity, minimized effort to adapt data into usable information, and abstraction.
Storing data in a flat file system, as the innkeepers do, and accessing the data directly pose problems
of data integrity. Anomalous data could easily arise if the innkeepers update a record in one file, but
do not take care to update related records in other files. Where data are kept in multiple, separate
files, but have a conceptual relationship to each other, a file system is of limited use compared to a
database management system (DBMS). A DBMS ensures that relationships between entities are
enforced.
By way of example, a GUEST entity might have a GUEST_ID attribute that appears in multiple
locations (e.g. a RESERVATIONS entity). In the file system model, the innkeepers may choose to
store addresses of guests in both GUEST and RESERVATION files in order to quickly access
address information while booking reservations. If the address is updated in one place, but not the
other, this results in a data anomaly, where the address attributes for a guest do not agree. A well–
designed database using a DBMS could circumvent this issue by storing no guest information in the
RESERVATION table other than GUEST_ID. With this relationship, guests' addresses can still

Question 1: Differentiate between database management system and information retrieval system by
focusing on their functionalities.
Database management system (DBMS) is an application which interacts with the database at some
point in its execution. While, the Information Retrieval System (IR) is the activity of gathering
information resources which related to information need from a collection of information resources.
Usually, we use metadata or full–text indexing in order to make a search on data requires.
Information Retrieval Systems are used to overcome what has been called as "information
overload". Many universities and public libraries use Information Retrieval System to provide
access to books, journals and other documents. For instance, Web search engines such as Google,
Yahoo and Bing, are the most visible IR applications.
There are several functions that DBMS performed to make sure the integrity of the data and data
consistency in the database such as data storage, retrieval and update, A user–Accessible catalogue,
transactional support, concurrency control services, recovery services, Authorization services,
support for data communication, integrity services, services to promote data independence and
utility services.
Meanwhile, an information retrieval process begins when a user enters a query into the system.
Queries are formal statements of information needs, for example search strings in web search
engines. In information retrieval a query does not

Data is at the centre of most today's businesses and businesses must pay close attention to how they
access, store and use data. One of the systems at the heart of current data management is different
database management system.
But as with most technology product out there, people have a wide range of database technologies
and systems to choose from. Picking out the most convenient for your business can be difficult.
This guide will hope to explain what database management systems are and what are the benefits for
using one. We'll also explain some of the most common distinctions between these technologies and
provide you a few tips on how to select the best system for your business.
Introduction to database management systems
What are database management systems (DBMS)? First, it's good to understand the different
components of DBMS. At the core of DBMS is database, which is essentially an organised
collection of data. The data in database is modelled in reality in a manner, which helps supports
processes that seek information.
Creating a database is simple, but you also need to be able to use the database for different
functions. This is where database management systems come to the rescue.
A DBMS is a computer software application, which helps to interact with the user of the database,
different applications, as well the database itself in order to gather and analyse data. A DBMS allows
interaction with the data, whether it is to create, analyse, delete or change

Relational Database Management System ( Rdbms )
Abstract
Relational database management system (RDBMS) have used for many decades. However, these
databases are facing several challenges with the requirements of many organizations like high
scalability and availability. They cannot deal with huge amount of data and requests efficiently. As a
result, famous organizations such as Google and Amazon shift from RDBMS to NoSQL databases.
NoSQL databases have several features that overcome issues. This paper explains features,
principles, and data models of NoSQL databases. However, the main focus of this paper is to
compare and evaluate two of the most popular NoSQL databases which are MongoDB and
Cassandra.

If you change your application, you have to change your database schema as well. This fixed
schema used by RDBMS make them impossible to quickly incorporate new types of data. Also, it is
a poor fit for unstructured and semi–structured data [14, 17].
Since queries require attributes from more than one table result in a join operation, join decreases
the performance of RDBMS. Joins and locks have a negative impact on performance of RDBMS
[4].
RDBMS provide limited replication techniques. In fact, these databases are based on consistency
instead of availability [14].
In order to understand NoSQL databases, chapter two will describe the most significant features of
NoSQL databases for solving the above mentioned requirements. Since the relational data model is
not suitable for some use cases, chapter three will explain structure and flexibility of different data
models offered by NoSQL databases. Chapter four will compare two of the widely used NoSQL
databases which are MongoDB and Cassandra.
2. BASE vs. ACID
Both RDBMS and NoSQL databases use principles that are derived from CAP theorem. According
to this theorem, following guarantees can be defined [8,12, 20]:
Consistency. All the users see the same data at any time.
Availability. When certain nodes fail, the other nodes in the system are able to continue and operate.

Introduction Information and data have become the cornerstone of business enterprises today.
Financial services organizations rely on important trade and market data, retail business rely on
consumer and market data, and military organizations are concerned with classified and national
security–sensitive data. As these organizations continue spend more time, effort, and money into the
management of this data, data base management systems are gaining more attention in Information
Technology Enterprise. This paper will discuss the advantages of using an Object Database
Management System (ODBMS) as opposed to the older a less flexible Relational Based Data
Management Systems.
Overview of Object Oriented Database Management Systems
The 1990s saw the emergence of ODBMS as the dominant data modeling application software. It
began in the 1960s and continued during the 1980s as technologists were searching for a more
flexible and capable way of dealing with data that fundamentally changed the way applications were
being designed. Object technology depicted data in terms of "classes" instead of representing it in
the strict table format of relational databases. A class is defined as the structure and code provided
by the programmer. It includes a description of the type of data, how it is stored, and its code.

Microsoft Sql Database Management System
Introduction and Methodology
Microsoft SQL Database Administrator Database plays a major role in any organization. As a
Database administrator(DBA) he/she is responsible in developing, implementing and maintaining
the databases and DBA 's are also responsible in updating, backup 's and security of the databases.
The first Database Management System was developed in the late 1960 's by two firms based on
their network data model but in the early 1970's a scientist of IBM introduced Relational database
theory after six years IBM completed prototype on RDBMS (relational database management
system). Oracle created the first versatile Relational Database Management Systems In 1983, which
allowed organizations to use their DBMS on different machines including mainframes,
workstations, and Pc 's. In 1993 Microsoft first created a database application called Access for
Macintosh machines. Microsoft SQL server is a RDBMS which is used to store and retrieve the data
by other software applications. There are 12 types of servers concentrated on various types of user 's
from single computer to large networks (Microsoft SQL DBA). I have pursued my under graduation
in Information Technology, during my course work I was more interested in databases and I have
developed special interest in making it as my career. I have learned basics of all database concepts
and I have attended extra tuitions and seminars to get in depth knowledge about it. In the last
semester of my master's program I

An Object Relational Database Management System
INTRODUCTION An object–relational database management system (ORDMS) is a DBMS that
supports both relational and object–oriented functions. SQL:1999 seems like the most innovative
update to the language since its induction, largely because of the adoption of object–oriented related
upgrades. COLLECTION TYPES "A collection is an ordered group of elements, all of the same
type." (Oracle 2002) With this addition it became possible to use set operators which allows for a
single result from two queries. Operator Returns UNION All distinct rows selected by either query

rows selected by both queries MINUS All distinct rows selected by the first query ... Show more
3. Varrays – this also uses sequential numbering as the key which makes its use ideal when trying to
access its contents in sequence. However, because varrays holds a fixed number of elements, the
method should be used when the amount of elements is predetermined. USER–DEFINED DATA
TYPES (UDT) UDTs have numerous ways of implementation. They act much like the typedefs in
the C language and can be used as defining a table, element, or even column type. Distinct user–
defined types of power allow the use of name equivalence instead of structural equivalence.
Compatible operations can be achieved by using the CAST operation. Structured user–defined types
allow for type inheritance which creates subtypes that inherit attributes and functions of their super
types or references types. "There are several reasons why UDT 's are useful within an object
database" (Burleson Consulting 2014): 1. Encapsulation – The existence of a complete entity. This
means once the data definitions, default values, and value constraints are defined uniformity and
consistency are guaranteed. Because of this, once nested UDTs will retain uniformity throughout the
database. 2. Reusability – Refers to the reuse of the hierarchy of common data structures which we
learned in a previous course saves coding time and insures uniformity. 3. Flexibility – This is
obvious in the name, User–Defined Data Type, as it allows great flexibility when creating
