Siam Commercial Bank to create centralised data warehouse

Siam Commercial Bank is to use technology from Teradata to replace a series of disparate, inconsistent data marts with a centralised enterprise data warehouse in an effort to improve business decision-making across the bank.

The first phase of the implementation will involve the extraction and transfer of all critical data and information currently stored in legacy systems across SCB's various business units. This data will then be consolidated within the centralised Teradata EDW platform, where it will present a single, holistic view of the bank's entire business. The outputs will be used to support functions such as personalised customer relationship management and marketing programmes, credit risk management strategies and financial analysis and reporting.

SCB previously deployed a data warehouse running primarily on its IBM mainframe computing environment along with several disparate data marts. This system served the bank's various business units as a decentralised, 'hub-and-spoke architecture'.

This set-up ultimately represented a higher total cost of maintenance and ownership, says Amarit Laorakpong, an executive vice president at SCB, and resulted in certain performance and scalability limitations. Because the data also varied among data marts across the bank, consistency problems were also created for business users who were unable to get a single view of the business.

States Laorakpong: "The Teradata EDW will help SCB realise a single view of our business."
