2007 - 2008 Informatica Developer

KSD, Noida

worked as an ETL developer. We have around 85 feeds coming in daily as flat files. I worked on 13 feeds. Each feed will have around 15 different validations which we have to implement while bringing the data to staging from flat file. We have 3 target tables in each mapping which are ETL_DATA, INVALID_DATA_LOG and UNMAPPED_DATA. All valid data should go to ETL_DATA. Any record that fails at least 1 validation goes to INVALID_DATA_LOG table. Any record that fails to lookup the legacy segments to extract current data segments should go to UNMAPPED_DATA table. I created couple of Mapplets for the validation. When a record fails a validation, we have to attach respective message to that record, like this a record may end up with no messages or couple of messages. I added Normalizer transformation to split the record to multiple records based on number of validations it failed and moved this data to INVALID_DATA_LOG table.

Analyzed business requirements and worked closely with the various application teams and business teams to develop ETL procedures that are consistent across all application and systems.

Involved in Extraction, transformation, loading and Implementation.

Extensively used various types of transformations such as source qualifier, Expression, Joiner, Update strategy, Aggregator, Lookup to load the data.

Used Session parameters, Mapping variable/parameters and created Parameter files for imparting flexible runs of workflows based on changing variable values.
