Analytical Data Warehouse

2002-2005 We develop a data warehouse for a major Austrian bank to support their cross selling business activities.

The requirement

The first production version of the data warehouse is already available after one month of development. It is based on an Oracle database and runs on Unix. A comprehensive cost analysis and a “Proof of Concept” are conducted by the customer in order to compare the recommended solution with the one used thus far (based on a mainframe system). The assessment falls in favor of the Oracle/Unix version recommended by us. The decisive factors for this are the much lower development and maintenance costs when compared to the mainframe based system.

The result

The Oracle-based solution becomes the standard for all future business intelligence solutions within the company. The analytical data warehouse will be comprehensively further developed and will become the base for a context based customer reference system.
