Data Quality Reporting DataMart - Data Extraction / ETL One of the prominent Bank in US wanted to build data mart hosting the data of quality checks performed on banking applications. My role was to extract the data from disparate data sources such as oracle, teradata, mainframe and SAS systems and build Informatica mappings to do quality checks and run profiling algorithms on the same. Later loading these results into Data mart hosted in Oracle. I developed reusable codes to perform calculations. I created mapplets for this and it saved lot of development efforts
