ETL Testing Online Training


Production Validation Testing (testing Data before moving in to production). Sometimes called  table balancing or  production reconciliation, this type of ETL testing is completed on Data as it is being moved in to production systems. The Data in the production systems has to be right in order to support your business decision taking. Informatica Data Validation Option provides the ETL testing automation and management capabilities to make positive that your production systems are not compromised by the Data update method.
Source to Target Testing (Data is transformed). This type of ETL testing validates that the Data values after a change are the expected Data values from the source. The Informatica Data Validation Option has a sizable set of pre-built operators to build this type of ETL testing with no programming skills necessary.
Application Upgrades (same-to-same as like ETL testing). This type of ETL testing validates that the Data coming from an older application or repository is the exact same as the Data in the new application or repository. Must of this type of ETL testing can be automatically generated, saving substantial check development time.
