2. Agenda or TOC
• The Analytical
• Data
, where there is no data to analyse to
where we have too much of data to analyse
• “
” used till date for this
•
we have a single structure for OLTP
and Analytics?
• The ‘data’
of data
• Data

4. Data Scenarios…
• New product design
• Simulation
• Knowledge
representation
No Data
Structured
Data
• From normalized
OLTP systems
• Variables , mostly
numbers
• Unstructured
• Quickly varying
• Mostly non-numeric
BIG data

5. Data analysis technology “names”
• Adhoc Data
& Queries
• Management Information
, Business Intelligence
• Business Analytics
• Real-Time BI
• Artificial
Analytics
• In-memory

6. Why can’t we analyze OLTP data
•
•
•
•
OLTP schema
Optimized for handling
transactions i.e., updates
Short and quick transaction
are catered
Multiple concurrent users
read small amounts of data
Key based, index lookups
used to access data
•
•
•
•
OLAP schema
Optimized for large loads of
data in ETL mode
Large summarizations to be
performed
Less number of users read
huge amounts of data
Full scans through data are
often required

7. The Data lifecycle
Sensing
ETL,
Warehousing
OLAP reporting
Acquiring,
Validating
Operational
Reporting,
Dashboarding
Analytics
Storing
Transactional
Update
Archiving,
Purging

8. Aspects of ‘Data’
Integration,
Migration

Quality
Visualization
