logic etl process assisted creation implementation business rules via stored procedures database package used different transformations like lookup joiner rank source qualifier transformations informatica designer created complex mappings using unconnected lookup sorter aggregator newly changed dynamic lookup router transformations populating target table efficient manner write etl specification create oracle procedure create mappings using owb 10gr2 load data multiple sources staging area written long sql blocks vertica database created process flow scheduled monitored session fixed specs defects technical coding defects data loads properly per business needs extensively worked various lookup caches like static cache dynamic cache persistent cache worked session logs workflow logs error handling troubleshooting responsible best practices implementation performance tuning levels error handling methods developed reusable transformations reusable mapplets wrote complex procedures incorporating exception handling performed data analysis validation upon completion conversion well various stored renon procedu procedures created various oracle db objects indexes materialized views synonyms constraints triggers packages performed cdc implemented scd participated meetings reviews status updates project lead business users written data validation test scripts verify data sources target written designed developed elt logic cleanse transform data target various sources using canonical tables developed various oracle sub functions like stored procedures

various sources like flat files oracle sql server extensively used features informatica including designer workflow manager extensively used repository manager workflow monitor associated design development around 40 mappings extensively worked sql queries created stored procedures packages triggers views using plsql programming optimized performance informatica mappings worked new transformation like java transformation transaction control validated complex mappings involving filter router expression lookup update strategy sequence generator joiner aggregator transformations used debugger test mapping fixed bugs created used debugger sessions debug sessions created breakpoints better analysis mappings created mapping variables parameters used appropriately mappings extensively used features informatica 86 including designer workflow manager repository manager workflow monitor designed developed several etl scripts using informatica unix shell scripts implemented slowly changing dimension methodology type 2 warehouse tables qa etl processes migrated informatica objects development qa production using deployment groups analyzed session logs bad files error tables troubleshooting mappings sessions involved performance tuning various levels including target source mapping session large data files large developed validation queries also used develop reports specified users extensively worked suite healthcare applications membership provider eligibility group product enrollment provider claims correspondence letters facilities customer also
