Distributed Query Processing
Distributed Query ProcessingMythili Kannan This document discusses distributed database and distributed query processing. It covers topics like distributed database, query processing, distributed query processing methodology including query decomposition, data localization, and global query optimization. Query decomposition involves normalizing, analyzing, eliminating redundancy, and rewriting queries. Data localization applies data distribution to algebraic operations to determine involved fragments. Global query optimization finds the best global schedule to minimize costs and uses techniques like join ordering and semi joins. Local query optimization applies centralized optimization techniques to the best global execution schedule.

Distributed concurrency control
Distributed concurrency controlBinte fatima This document discusses concurrency control algorithms for distributed database systems. It describes distributed two-phase locking (2PL), wound-wait, basic timestamp ordering, and distributed optimistic concurrency control algorithms. For distributed 2PL, transactions lock data items in a growing phase and release locks in a shrinking phase. Wound-wait prevents deadlocks by aborting younger transactions that wait on older ones. Basic timestamp ordering orders transactions based on their timestamps to ensure serializability. The distributed optimistic approach allows transactions to read and write freely until commit, when certification checks for conflicts. Maintaining consistency across distributed copies is important for concurrency control algorithms.

Underlying principles of parallel and distributed computing
Underlying principles of parallel and distributed computingGOVERNMENT COLLEGE OF ENGINEERING,TIRUNELVELI Parallel and distributed computing allows problems to be broken into discrete parts that can be solved simultaneously. This approach utilizes multiple processors that work concurrently on different parts of the problem. There are several types of parallel architectures depending on how instructions and data are distributed across processors. Shared memory systems give all processors access to a common memory space while distributed memory assigns private memory to each processor requiring explicit data transfer. Large-scale systems may combine these approaches into hybrid designs. Distributed systems extend parallelism across a network and provide users with a single, integrated view of geographically dispersed resources and computers. Key challenges for distributed systems include transparency, scalability, fault tolerance and concurrency.

Concurrency Control in Distributed Database.
Concurrency Control in Distributed Database.Meghaj Mallick The document discusses various techniques for concurrency control in distributed databases, including locking-based protocols and timestamp-based protocols. Locking-based protocols use exclusive and shared locks to control concurrent access to data items. They can be implemented using a single or distributed lock manager. Timestamp-based protocols assign each transaction a unique timestamp to determine serialization order and manage concurrent execution.
Interaction Modeling
Interaction ModelingHemant Sharma Interaction modeling describes how objects in a system interact and communicate through message passing. It uses several UML diagrams including use case diagrams, sequence diagrams, activity diagrams, and collaboration diagrams. A use case diagram shows relationships between actors and use cases, while a sequence diagram depicts the temporal order of messages exchanged between objects to complete a scenario. An activity diagram models system workflows and dependencies between activities. A collaboration diagram displays message flows between objects to achieve a particular task.

Context model
Context modelUbaid423 The document discusses context models and their use in system modeling. Context models illustrate the operational context of a system by showing what lies outside its boundaries, including other systems in the environment. They help define a system's boundaries and show how IT applications fit into the context of people and organizations. Two examples are provided: (1) a Mental Health Care Patient Management System (MHC-PMS) and its connections to other clinical systems; (2) an Automated Teller Machine (ATM) and its links to banking systems. Context models on their own do not show relationships between external systems, so additional models are needed.
Distributed database
Distributed databaseReachLocal Services India A distributed database is a collection of logically interrelated databases distributed over a computer network. A distributed database management system (DDBMS) manages the distributed database and makes the distribution transparent to users. There are two main types of DDBMS - homogeneous and heterogeneous. Key characteristics of distributed databases include replication of fragments, shared logically related data across sites, and each site being controlled by a DBMS. Challenges include complex management, security, and increased storage requirements due to data replication.
Temporal databases
Temporal databasesDabbal Singh Mahara The document discusses temporal databases, which store information about how data changes over time. It covers several key points:
- Temporal databases allow storage of past and future states of data, unlike traditional databases which only store the current state.
- Time can be represented in terms of valid time (when facts were true in the real world) and transaction time (when facts were current in the database). Temporal databases may track one or both dimensions.
- SQL supports temporal data types like DATE, TIME, TIMESTAMP, INTERVAL and PERIOD for representing time values and durations.
- Temporal information can describe point events or durations. Relational databases incorporate time by adding timestamp attributes, while object databases

Overview of physical storage media
Overview of physical storage mediaSrinath Sri - Physical storage media can be classified by access speed, cost per unit of data, and reliability. This includes cache, main memory, flash memory, magnetic disks, optical disks, and magnetic tapes.
- Faster but more expensive media like cache and main memory are primary storage, while magnetic disks represent secondary storage. Tapes and optical disks provide tertiary, offline storage.
- Volatility also differs, with volatile storage like main memory losing data on power loss, while nonvolatile media like disks and flash retain data. The database typically resides on nonvolatile secondary storage for long-term access.
Aspects of data mart
Aspects of data martOsama Hussain Paracha This document discusses various aspects of data marts, including external data, reference data, performance issues, monitoring requirements, and security. External data is stored in the data warehouse to avoid redundancy. Reference data cannot be modified and is copied from the data warehouse. Performance considerations for data marts are different from OLAP environments, with response times ranging from 1 minute to 24 hours. Monitoring helps track data access, users, usage times, and content growth. Security measures like firewalls, login/logout, and encryption are needed to protect sensitive information in data marts.

Lock based protocols
Lock based protocolsChethanMp7 This document discusses lock-based protocols for concurrency control. It describes that locks can be requested in exclusive or shared mode to control concurrent access to data items. A lock compatibility matrix is used to determine if a requested lock is compatible with existing locks held by other transactions. The Two Phase Locking protocol is introduced to ensure conflict serializable schedules by restricting transactions to an growing phase where they only acquire locks and a shrinking phase where they only release locks.
Phases of distributed query processing
Phases of distributed query processingNevil Dsouza The document discusses phases of distributed query processing. The objectives are to convert SQL queries to relational algebra, minimize costs by executing queries efficiently across distributed databases, and simplify queries. Analysis involves lexical, syntactic and semantic analysis to verify relations and attributes. Simplification detects redundant predicates. Query restructuring rewrites queries as relational algebra expressions and applies transformation rules. Fragmentation forms queries for fragmented relations and reduction techniques optimize queries based on the fragmentation type.

When the map is rendered, objects of this spatial data are used to project the location of the objects on 2-Dimentional piece of paper.
The spatial data management systems are designed to make the storage, retrieval, & manipulation of spatial data (i.e points, lines and polygons) easier and natural to users, such as GIS.
While typical databases can understand various numeric and character types of data, additional functionality needs to be added for databases to process spatial data types.
These are typically called geometry or feature.

java Oops.ppt
java Oops.pptRanjith Alappadan This document discusses key concepts in object-oriented programming including classes, objects, methods, abstraction and encapsulation, inheritance, and polymorphism. It defines a class as a user-defined data type that includes attributes. An object is an instance of a class that has behaviors, holds information, and can interact with other objects. A method defines the behavior of an object. Abstraction and encapsulation involve hiding details and binding data and functions together. Inheritance allows a class to acquire properties of its parent class. Polymorphism allows different behaviors in different instances.

Non-Relational Postgres
Non-Relational PostgresEDB This presentation by Bruce Momjian. Co-Founder of the Global PostgreSQL Development team and a Senior Architect at EDB. He demonstrates how to use arrays, geometry and JSON for NoSQL data types to overcome restrictions of relational storage to support new innovative applications, specifically by storing and indexing multiple values, even unrelated ones, in a single database field. Such storage allows for greater efficiency and access simplicity, and can also avoid the negatives of entity-attribute-value (eav) storage.
Postgres has always had strong support for relational storage. However, there are some cases where relational storage might be inefficient or overly restrictive.
Object oriented programming Fundamental Concepts
Object oriented programming Fundamental ConceptsBharat Kalia The document discusses four fundamental principles of object-oriented programming (OOP): inheritance, abstraction, encapsulation, and polymorphism. Inheritance allows classes to inherit attributes and behaviors from parent classes. Abstraction focuses on relevant properties and hides unnecessary details through techniques like abstract classes and interfaces. Encapsulation hides internal implementation details and exposes a public interface through properties and methods. Polymorphism enables classes to take on multiple forms through inheritance and method overriding.
Object Oriented Concept
Object Oriented ConceptD Nayanathara OOP concepts include classes, objects, methods, encapsulation, inheritance, and polymorphism. A class acts as a blueprint that defines properties and behaviors of an object. Objects are instantiated from classes and can have different property values. Methods define object behaviors. Encapsulation bundles data and methods into a class and hides implementation details. Inheritance allows subclasses to inherit properties and behaviors from parent classes. Polymorphism enables the same method to process different types of objects.

UNIT I Introduction to NoSQL.pptxRahul Borate NoSQL databases provide an alternative to traditional relational databases that is well-suited for large datasets, high scalability needs, and flexible, changing schemas. NoSQL databases sacrifice strict consistency for greater scalability and availability. The document model is well-suited for semi-structured data and allows for embedding related data within documents. Key-value stores provide simple lookup of data by key but do not support complex queries. Graph databases effectively represent network-like connections between data elements.

Default and On demand routing - Advance Computer Networks
Default and On demand routing - Advance Computer NetworksSonali Parab Routing is the process of selecting best paths in a network. In the past, the term routing was also used to mean forwarding network traffic among networks. However this latter function is much better described as simply forwarding. Routing is performed for many kinds of networks, including the telephone network (circuit switching), electronic data networks (such as the Internet), and transportation networks.
In packet switching networks, routing directs packet forwarding (the transit of logically addressed network packets from their source toward their ultimate destination) through intermediate nodes. Intermediate nodes are typically network hardware devices such as routers, bridges, gateways, firewalls, or switches. General-purpose computers can also forward packets and perform routing, though they are not specialized hardware and may suffer from limited performance. The routing process usually directs forwarding on the basis of routing tables which maintain a record of the routes to various network destinations. Thus, constructing routing tables, which are held in the router's memory, is very important for efficient routing. Most routing algorithms use only one network path at a time. Multipath routing techniques enable the use of multiple alternative paths.
Cloud Computing And Virtualization
Cloud Computing And VirtualizationSonali Parab This document discusses the history and characteristics of cloud computing.

Key aspects include maximizing shared resources, dynamic reallocation of resources based on demand, and access to applications via the internet without direct installation. The document then covers the history of cloud computing from the mainframe era to modern cloud services. It describes characteristics like agility, cost reduction, scalability and elasticity. Finally, it outlines the common cloud service models of Infrastructure as a Service, Platform as a Service and Software as a Service.
Protocols in Bluetooth
Protocols in BluetoothSonali Parab The document discusses the protocol layers in Bluetooth technology. It describes that Bluetooth uses a hierarchical model with different protocol layers, each performing specific communication tasks. Some key layers mentioned are the baseband layer, link layer, host controller interface, logical link control applications protocol, RF communications protocol, and service discovery protocol. The document provides details on the functions of different Bluetooth protocol layers like the baseband layer managing the radio interface and link management protocol handling link setup between devices.
Protols used in bluetooth
Protols used in bluetoothSonali Parab Protocol layers are a hierarchical model of network or communication functions. The divisions of the hierarchy are referred to as layers or levels, with each layer performing a specific task. In addition, each protocol layer obtains services from the protocol layer below it and performs services for the protocol layer above it. The Bluetooth system divides communication functions into protocol layers.
The Bluetooth system consists of many existing protocols that are directly used or have been adapted to the specific use of the Bluetooth system. Protocols are often divided into groups that are used for different levels of communication (a protocol stack). Lower level protocols (such as protocols that are used to manage a radio link between specific points) are only used to create, manage, and disconnect transmission between specific points. Mid-level protocols (such as transmission control protocols) are used to create, manage, and disconnect a logical connection between endpoints that may have multiple link connections between them. High level protocols (application layer protocols) are used to launch, control, and close end-user applications.
Some of the layers associated with the Bluetooth system include the baseband layer (physical layer), link layer, host controller interface (HCI), logical link control applications protocol (L2CAP), RF Communications protocol (RFCOMM), Object Exchange (OBEX), and service discovery.

Remote Method Invocation
Remote Method InvocationSonali Parab Remote Method Invocation (RMI) allows objects running in one Java virtual machine to invoke methods on objects running in another Java virtual machine. RMI uses object serialization to marshal and unmarshal parameters and supports true object-oriented polymorphism. RMI is implemented using three layers - stub, remote reference, and transport connection layers. The stub and skeleton hide the underlying network implementation details and allow remote objects to be called similar to local objects. Security is an important consideration in RMI and a security manager must be installed and permissions configured to control access to remote objects and classes.
Agile testing
Agile testingSonali Parab “Software Testing is the process of executing a program or system with the intent of finding errors. Or, it involves any activity aimed at evaluating an attribute or capability of a program or system and determining that it meets its required results”
Currently Agile is one of the highly practiced methodologies. Agile is an evolutionary approach to software development which is performed in a highly collaborative manner by self-organizing teams that produces high quality software in a cost effective and timely way which also meets the changing needs of its stakeholders. The software is delivered to the customer very quickly; customer checks it for errors and sends some new changes and requirements to include before the last iteration. So, user is provided with a chance to test the product and provide the team with feedback about the working and the functionality of the system. Agile development approach believes in the involvement and frequent communication between the developer team and stakeholders, and regular delivery of functionality. According to Agile development, people are more important than processes and tools; and the customer must be involved in the entire process.

April 30, 2025
ABSTRACT: I give an introductory discussion of two key philosophical controversies in statistics in relation to today’s "replication crisis" in science: the role of probability, and the nature of evidence, in error-prone inference. I begin with a simple principle: We don’t have evidence for a claim C if little, if anything, has been done that would have found C false (or specifically flawed), even if it is. Along the way, I’ll sprinkle in some autobiographical reflections.
