Case Study
GE Medical
As an Informatica Developer for GE, Athena Group designed, developed, and deployed Informatica mappings and associated functionality in an Item Costing and Product Inventory Data Mart. The environment at GE consisted of a blend of many Data Marts, which made-up the Data Warehouse. The warehouse employed highly complex data transformations including Slowly Changing Dimensions and a series of Stored Procedures, which made performance tuning and efficient mapping highly critical. Along with designing mappings from scratch, Athena Group re-wrote existing code to enhance performance and troubleshoot errors in both Oracle8I and Informatica.
