Role Developer
Duration Octobar-2006 to March 2008
Franklin Templeton Investments (“FTI”) has embarked on a program to implement and consolidate
its current and historical enterprise products information into a single data source (EW), based on
Industry Standard Product Hierarchy. FTI has requested Cognizant to provide technical resources and
expertise in assisting FTI in evaluating and selecting the best solution to fit its requirements and
support its business case.
The Product Data Load (PDL) project has been chartered to make the Enterprise Warehouse (EW) and
Global Integrated Data store (GID) as the go-to sources of reference for historical and current retail
and institutional enterprise product data. The key objective of the project is to present rationalized
and “clean” enterprise product data that can be leveraged by applications downstream.
Listed below are the business drivers for the PDL initiative.
Currently the Products and the data elements are not synchronized between GID & EW
Multiple flows exist between the source systems and to GID and EW thereby introducing
redundancies and inconsistencies in the data between GID and EW and hence other downstream -
Data Quality Challenges
Maintenance redundancies for the multiple flows
The current GID model is based on the off-the-shelf Street books data model. The Street books model
is based on a Name-Value Pairs design pattern that adds overheads to the query retrieval.
Currently the websites that are the primary consumers of the data from the GID have limited Search
& Navigation capabilities for analysis due to lack of a consistent and coherent product categorization.
Historical data retention is not consistent across various products leading to inconsistencies.
Responsibility:
As a Developer my responsibilities include
 Mainly involved in ETL designing and coding.
 Analyzing the sources and targets, transforming the data, mapping the data and populating
the data into targets by using Informatica Designer, Workflow Manager and Workflow
Monitor.
