3. 3 BILLING MODERNIZATION – phase II objectives Retirement of the legacy DTC and NSCC billing systems Standardized data integration processing End-to-End balancing Enhanced MIS capabilities for those interfaces utilizing/converting to UBF Retirement of the legacy DTC and NSCC billing systems Standardized data integration processing End-to-End balancing Enhanced MIS capabilities for those interfaces utilizing/converting to UBF

4. 4 BILLING MODERNIZATION – phase II Appx. 85 Interfaces (appx. 50 million rows daily -summarized to appx..5 million rows monthly)

5. 5 DATA INTEGRATION - requirements Source data from a wide range of sources (predominantly mainframe sources) Write data to a wide range of targets Transform data according to billing rules Process more than 50 million transactions per day Source data from a wide range of sources (predominantly mainframe sources) Write data to a wide range of targets Transform data according to billing rules Process more than 50 million transactions per day

9. 9 ETL – tool selection process – stage A Stage A: Pre-screen the ETL products and short-list two products. Step1: Pre-screened the vendors: The following four vendors were selected based upon previous experience, market share and published reports. Ascential DataMirror Informatica SAS Step2: Requested information and product demonstration. Step3: ETL tool selection committee discussed and evaluated the information and two products were selected for further evaluation. Stage A: Pre-screen the ETL products and short-list two products.

10. 10 ETL – tool selection process – stage B Stage B: Final selection of the product Step1: Developed and documented comprehensive list of evaluation criteria, success criteria and weight based upon consultation with various stakeholders. Step2: Evaluated the two vendor products through a well defined/documented “proof of concept” process. Step3: Made the final selection based upon evaluation-score and price.
