Project Details:
Client Name : Bank of New York Mellon - New York
Duration : 1st July 2009 to Till date
Project 1.1 : BNYM - COD-CRS- CIW Warehouse
Role: ETL Developer
Project description:
The objective of this project is to create a new data warehouse (CRS) for
The Bank of New York Mellon Customers. The new data warehouse CRS (Customer
Reporting System) is developed by sourcing data from two systems.
. Legacy Bank of New York data warehouse COD (Custody Operational Data
warehouse)
. Heritage Mellon custody and accounting systems CMS (Custody Management
System) and IAS (Institutional Accounting System)
CRS is built to store data necessary for generating drill-down reports
which provide cash & custody data. CRS is now renamed to CIW (Client
Information Warehouse). CIW will initially be populated by only legacy COD
system and will eventually be integrated by Mellon's custody & accounting
source systems.
Tools and DB Used :
Informatica Powercenter, Power exchange ( 8.1, 8.6 ), DB2
Project 1.2 : BNYM-EECS-CIW-BAU-ETL
Role: Senior ETL Developer
Project description:
The new data warehouse named- Client information Warehouse (CIW) has been
developed for Bank of New York Mellon Customers for generating Cash &
Custody reports by sourcing data from two systems.
The objectives of this project are
. Add modules (MQ-CASCADE, MUTUAL FUND ) into CIW for the new business
Integrate IAS, CMS into CIW
. Modifying the existing modules as business change
. Modifying the Existing code to load data into both Db2 and Oracle Exadata
databases
Tools and DB Used : Informatica Powercenter, Power exchange ( 9.1), DB2, Oracle Exadata, IBM Webshere MQ
Project 1.3 : BNYM-FUND ACCOUNTING
Role: ETL Lead
Project description:
The objectives of this project are,
. Create a new Subsystem named Fund Accounting System (FA) under CIW to
