  • 10. Pranabesh Ghosh Page 10 Role Developer Duration Octobar-2006 to March 2008 Company Cognizant Technology Solutions India Pvt. Ltd Project Description: 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.   Creating and optimizing the Mappings, Sessions, and Workflows to improve the load performance.  Creation of Sessions, Workflows and Parameter files using UNIX for the corresponding mappings.
