DATA WAREHOUSING (DW), WHAT IS IT?

1. It is combining data from multiple and usually varied sources into one comprehensive and easily manipulated database.

2. DW includes queries, analysis and reporting. Because data warehousing creates one database in the end, the number of sources can be anything you want it to be, provided that the system can handle the volume, of course.

3. The final result, however, is homogeneous data, which can be more easily manipulated.

WHY DATA WAREHOUSING (DW)?

DW is commonly used by companies to analyze trends over time.

In other words, companies may very well use data warehousing to view day-to-day operations, but its primary function is facilitating strategic planning resulting from long-term data overviews.

From such overviews, business models, forecasts, and other reports and projections can be made.

DW is not the be-all and end-all for storing all of a company's data. Rather, data warehousing is used to house the necessary data for specific analysis.

WHY “DATA WAREHOUSING (DW)” IS PREVALENT IN BANKING?

A. Banks worldwide use DW solutions normally for profitability analysis and to enhance their risk management capability.

B. Customer Relationship Management (CRM) solutions are also being increasingly deployed by banks to enhance their ability to manage and grow their customer base in the most desired manner.

SYBASE IQ

Let us learn about Sybase IQ by the following:

1. What is Sybase IQ?2. Why do organizations need Sybase IQ?3. What is unique about Sybase IQ?

1. WHAT IS SYBASE IQ?

•Sybase IQ is a highly optimized analytics server, designed specifically to deliver ultra-high-speed business intelligence and reporting on standard hardware and operating systems.

•Sybase IQ is architected for analytics—not transactions—with a structure.

•The patented indexing makes it the preeminent choice for data warehousing and reporting.

•Sybase IQ provides a reduction in disk and CPU requirements (by reducing I/O bottlenecks) compared to traditional systems that have to be retro-fitted to support Data Warehousing and Analytics.

2. WHY DO ORGANIZATIONS NEED SYBASE IQ?

Most organizations are struggling to deal with data

management and data growth. As

data explodes, so does the cost of managing that

data. They apply

more processing

power to deal with very large databases and

increasing numbers of

users, with low cost.

Although the “hard costs” of

storage are decreasing, the

“soft costs” associated with

maintaining data are

substantial. Sybase IQ resolves all

these business pains.

3. WHAT IS UNIQUE ABOUT SYBASE IQ?

Faster—Delivers ad hoc

query performance up

to 100 times faster than a

traditional systems.

Lower TCO—Requires less

storage by compressing raw data up to 70%, while traditionally databases explode data by 150-500%.

Easier—Easier to maintain than

traditional databases and

does not require time and resource intensive tuning to

obtain excellent performance.

More Scalable—Offers near

linear user and data scalability

to support thousands of

users and terabytes of data.

PNB BANK

PNB bank is one of India’s largest nationalised bank. The bank has a network of 1,308 branches and 3,950 ATMs as well as robust Internet banking. PNB Bank offers a wide range of banking products and financial services to corporate and retail customers through a variety of delivery channels and through its specialized subsidiaries and affiliates in the areas of investment banking, life and non-life insurance, venturecapital and asset management.

PNB BANK – SYBASE IQ

In India, PNB bank is the pioneer in implementing a data warehousing (DW) solution, which is powered by Sybase IQ, a highly optimized business intelligence, analytics and data warehousing solution for delivering dramatically faster results at a low cost.

Previously, the bank was dependent on its DW from “Teradata”. With dramatic growth in its users, amount of data, and source stations, etc., the increasing cost of scaling and maintenance and mounting system unavailability posed difficulties for the bank. To resolve these recurring problems, the bank undertook a migration of the enterprise data warehouse from Teradata to Sybase IQ.

Applauding the strength of Sybase IQ, Pravir Vohra, Group Chief Technology Officer, says, “Our business requirements were addressed well with minimum infrastructure. Sybase IQ is an excellent product.”

SYBASE IQ – THE PREFERRED CHOICE

PNB Bank was using “Teradata” for its data warehouse. The closed box architecture of Teradata imposed restrictions on scalability. Secondly, querying and loading could not happen simultaneously. Queries could only be run during business hours because the loading of data had to take place during off-business hours. The queries did not reflect the most current data.

These issues compelled PNB Bank to look for more efficient and flexible solutions. The solution would have to address not only current issues, but accommodate future growth expectations and business requirements.

During this rigorous testing, Sybase IQ delivered faster results on independent hardware and operating systems with minimum infrastructure.

TRANSFORMATION OF DATA TO SYBASE IQData from approximately 14 source systems is extracted and

loaded on to the writer node of Sybase IQ, hosted on IBM System p-series hardware. The enterprise SAN storage is connected to both the reader and write node and the business users run queries on the reader node of Sybase IQ. The prime challenge faced by the Sybase team was that ICICI Bank wanted the migration to be transparent to business users.

More than three Terabyte of data was required to be moved into Sybase IQ, typically requiring a large amount of time and storage using traditional systems. However, Sybase IQ achieved an exceptional speed of two million records per second, so data loading with Sybase IQ took a mere two days. The entire migration process for the new system took less than three months.The simplicity of the system is exhibited by the fact that DBAs, developers and business users were running on the new system after only a five day training session.

FUNCTIONALITY OF SYBASE IQ IN PNB BANK1. The source systems maintain data from various divisions of ICICI

Bank like its Retail Banking (liabilities and assets), call centre, Internet Banking and Demat units, supporting over 3.5 TB of data.

2. Using Sybase IQ’s unique concurrent user scalability, ICICI Bank now supports over 150 users without any performance degradation.

3. Sybase IQ drastically reduced query time. Queries that used to take over four hours before, now complete in a quarter of the time.

4. Additionally, system maintenance has been streamlined and can be carried out by “in-house developers”.

5. With the Teradata warehouse, loading scripts were run, which made the system difficult to modify and maintain. However, with the new system, load automation has been achieved through Sybase IQ stored procedures.
