Because of the bank’s rapid growth, more and more difficulties were arising with generation of statutory reporting, and the bank didn’t have a tool to generate consolidated reports. All divisions of the bank were extremely interested in a tool that could allow them to quickly obtain reliable analytical data. Unavailability of appropriate tools led to a need of generating reports manually, which caused low speed and poor quality of the reports issued. Given the situation at hand, management of the bank decided to implement a full-scale single corporate data storage that would meet requirements as to preparation of reports for all departments of the bank. To solve the above problem, AT Consulting professionals were engaged who proposed to deploy a data storage based on Oracle DBMS , and ETL tools, i.e. Informatica and SAP BusinessObjects BI tools.
