Informatica DVO

Informatica offers a testing solution called Data Validation Option for PowerCenter (DVO).

The DataValidator for PowerCenter product was originally developed by a company DVO SOFTWARE. It is now available under the Informatica brand as Informatica PowerCenter Data Validation Option.

DVO is a custom tool built on top of Informatica PowerCenter. DVO integrates with the Informatica PowerCenter Repository and Integration Services and enables developers and business analysts to create rules to test the data being transformed during the data integration process.

Informatica mentions the following ETL Testing Use Cases: Production Validation Testing, Source to Target Testing and Application upgrades.

Amongst others, it features:

  • An easy-to-use GUI interface to test the rules created for data validations for multiple projects.
  • No programming skills needed to create validation tests.
  • A repository with reporting capabilities to provide a complete audit trail of all tests and their results.
  • Reading data definitions from PowerCenter metadata repositories and can easily deal with data definition changes.

Note that DVO tests data only, not mappings or workflows. Testing mappings is unit testing, which is different from data validation.

As DVO is a commercial product it may be attractive to Informatica Power Center users. At this moment, no free trial seems available (Feb 9, 2020).
