Description

I played important role in this project to develop and build Forensic Data Warehouse, Data Mart using Informatica PowerCenter for ETL, Oracle Database 11g for OLTP and OLAP (supports growth and scale), sourcing data from Fidelity’s GRC system (IBM Open Pages), their surveillance systems (e.g., Actimize), BRM spreadsheets, and other source systems and finally produce data for OBIEE to display the results of forensic tests, provide ad-hoc analytics and data drill downs capabilities to the Compliance end user. A goal for the Forensic Data Warehouse is to reduce the complexity and redundancy of the many schemas supporting other various Compliance applications.
