1. Ab Initio
From the Data Warehousing
Perspective

2. Data Warehousing
Why did it arise?
 Large Corporations gathered huge amounts of
data.
 Sooner, they were data rich but information
poor.
 Large body of disparate data, difficult to make
informed business decisions.

3. Solution!!!
 Users wanted more control over their data
 Each department request data specific to their
department.
 Varying amounts of data from the same
source.
One Solution to the PROBLEMS---
Information/Data Warehouse.

4. What is Data Warehousing?
 Data Warehousing is an architecture
 System for storing, retrieving and managing
large amounts of any type of data.
 Data warehousing concerned in moving data
from its current location to the data warehouse
and transforming data into information.

5. E.T.L-----What is it??
 E.T.L stands for Extraction, Transformation
Loading.
 This is the principle used in Data Warehousing

6. Characteristics of Data Warehousing
 Application independent
 Collected at any moment in a business cycle.
 Metadata has been created for it.
 Easily understood by a non-technical

7. Characteristics of data in data warehouse
 Subject Oriented
 Integrated
 Non-volatile
 Time Variant

8. Subject-Oriented
 Focus on entities rather than on process.
 A Subject-Oriented data warehouse is called a
Data Mart

9. ETL Tools
 Many tools are being used in Data
Warehousing for the purpose of ETL.
 Ab Initio is one of the major ETL tool.

10. What is Ab Initio?
 Latin word, meaning “From First Principles”
 ETL tool, developed by Ab Initio software
corporation (http://www.abinitio.com)
 Used in data warehousing, batch processing
and application integration.

11. Why Ab Initio?
 Achieving Scalability
 Reduced Development Time
 Managing Metadata
 Integrating Other Applications

12. Features
 Basic Components: Filter by Expression, Reformat, Sort, Join,
Rollup, Dedup
 Database Components: Input, Output and Update Table;
db_config_utility
 Built in Functions: Ab Initio built-in functions are those which
 can manipulate strings, dates, and numbers
 can access system properties
 Vectors: An array of same type of elements that is repeated

13. Look Up Function
 Built-in function within a transform function that
allows a transform component to retrieve records
from a look up file
 Held in main memory
 Faster as searching and retrieval is key based
 Not connected to other components in a graph

14. Alternatives for Ab Initio
 Informatica and Ascential are alternatives for
Ab Initio but the main disadvantage is they are
tougher to work with.

15. Highlights
 Every plug-in facility available from industry
leaders Informatica and Ascential incorporated
into Ab Initio
 Fastest ETL, possible to extract 41 million
rows of data from an Oracle 8i database
(Geneva billing system!) in about 5.2 minutes

16. Success Stories
 Bank of Montreal-Moving 10 terabytes (TB)
of data daily and analyzing it done using Ab
Initio
 Premier Inc. (www.premierinc.com health
care services) successfully handled 14 TB of
data using Ab Initio to achieve scalability and
data quality

17. End
 Thank You for your time!!
