Oracle Analytics Cloud
● Oracle’s Cloud Analytics platform based on OBIEE and Oracle DV technology
● Customer-managed or Oracle-managed (Autonomous Analytics Cloud)
● Available in three editions
○ OAC Standard
○ OAC Data Lake
○ OAC Enterprise

Three Key Components of OAC Data Lake
Oracle Data Visualization
(OAC Standard Edition)
Oracle Essbase Cloud
Data Flows &
Data Lake Analysis

● Explore, catalog and discover data in Oracle Big
Data Cloud, Oracle Database
● Enrich and transform raw data into valuable
information and insights
● Analyze at-scale data using Data Visualization
● Combine data from SaaS, social and real-time
● Create predictive and classification models
● Analyze the sentiment in social media feeds

But what’s a Data Lake?

What Is a Data Lake?
● Complements a data warehouse
● Landing area for unstructured and
semi-structured data for analysis
● Flexible data storage platform with
cheap storage, flexible schema
support + compute
● Use-cases include
○ Storing data intended for
multiple query engines
○ Landing data for initial discovery
○ Storing high-volume granular
event data from Event Hub

What Is a Data Lake?

Creates new insights +
models using tools such as
R and sampled data
Helps people understand
insights from data that
they’ve unearthed
Data Engineers
Makes at-scale data consumable in
some form, either directly or
by data scientists and data analysts
Data Scientists Data Analysts
Data Lake User Personas

Data Engineers
● Can code, run clusters
● Create data pipelines & prepare data
● and build predefined ML models
● Knowledge of the math of ML limited
● They may be DBAs, BI developers
● Experience with DevOps, cloud

OAC Data Lake Features for Data Engineers
12
● Explore, catalog and discover data in Oracle Big Data Cloud, Oracle
Database
● Enrich and transform raw data into valuable information and insights
● Analyze at-scale data using Data Visualization
● Combine data from SaaS, social and real-time
● Create predictive and classification models
● Analyze the sentiment in social media feeds
● Data engineering without the hand-coding

Managing and Cataloging the Cloud Data Lake
30
● Catalog of all data assets in projects
● Connection to Hive Thrift Server
● IoT and Social Media Data Sets
● Data Flows and Sequences
● Managed data lake store
● Control the lifecycle of your
data lake assets
● Security
● Scheduling

Data Preparation Features from OAC Standard Edition
31
1. Split timestamp field
that’s not in valid format
2. Choose “space”
character as delimiter
3. Convert the first split
column into a date datatype
4. Choose the correct date
format for this field’s values
5. Repeat for the TIME split
column, concatenate with ’T’
in-between and finally convert
resulting field into TIMESTAMP

Data Flows are sequences
of data transformations
executed on the BI Server -
Spark execution on
roadmap for OAC DL
Create
Essbase Cube
Time Series
Forecast
Sentiment
Analysis
Predictive / ML
Model Train and
Build
Run custom R and
other python
scripts
Extended Data Flow Capability for Data Lake Edition
Data Flows are based on
the technology previously
announce as “Dataflow
ML”, now delivered as part
of Oracle Analytics Cloud

Example : Enrich With Sentiment, Then Visualize
33
1. Add Sentiment Analyse
step to data flow, persist
final enriched dataset
back to Hive table
2. Add a calculation to convert
sentiment description values to
positive/negative cumulative
score
3. Analyze Results in Data
Visualization UI

Using Explain Feature to Automate Deriving Context
34
1. Right-Click on attribute or
measure column to “explain”
the drivers of its values 2. ML algorithm explains basic
facts, drivers, anomalies and
identifies segments of interest

Display Selected Column Explanations on Dashboard
35

Transform, Aggregate and Join Datasets
36
Multi-step dataset joins
Aggregate Datasets
Binning and Grouping

Predictive Modeling and Forecasting
37
1. Select Prediction Model best
suited to predicting Kudos from
Strava bike rides
2. Select column whose
values are to be predicted,
and model parameter values
3. Train model and then test
against remaining dataset

Analyzing Data At-Scale Hosted on Big Data Cloud
