Architected Informatica tools Power Center and Power Analyzer on different servers including user and security setup for different environments. Involved in the setup of repositories, promoting code on different environments and versioning of objects.
- Involved in business analysis and modeling of HTS mart (high throughput screen data - experiments) and mapping the source and target matrices, data cleansing and data profiling activities at source and target objects.
- Worked with ETL team for loading data from various sources into Staging / Data Warehouse and Data Marts using Informatica Power Center 7.1.x (Repository Manager, Designer, Server Manager, Workflow Manager, and Workflow Monitor)
- Extensively used Informatica debugger to validate mappings and to gain troubleshooting information about data and error conditions.
- Coded for loading large volumes of data in fact tables to the tune of 1.2 billion rows using source partitioning and parallel partitioning at the target. Used multiple sessions with bulk load option for performance
- Performance tuning for power center included design changes, splitting mappings into multiple mappings, changing cache values, having multiple sessions, using parallel partitions at different stages of the mappings at session level and using only fields needed at the target level from the source.
- Responsible for ETL process includes data extraction, cleansing, aggregation, reorganization, transformation, calculation, and loading assay data. Responsibilities included data modeling using TOAD to implement star schema data warehouse and data marts for experimental data using Oracle. Created search capabilities to drill up data from the data mart to the data warehouse. Created dynamic pivot for data mart was very efficient since the source data was run in multiple threads to process the data efficiently and made it scalable.
