The Data Validation Option reports run against the reporting views. You can build custom reports based on the reporting views.
The Data Validation Option installer installs the reporting views in the Data Validation Option repository. If you create a custom report, build the report based on the views. Do not build reports based on the underlying database tables because the Data Validation Option repository metadata can change between versions.
Data Validation Option stores version history for objects and test runs in the Data Validation Option repository. The Data Validation Option repository contains versions of single-table constraints, table pairs, join views, lookup views, SQL views, and the tables and files included in each of these objects. The Data Validation Option repository also stores the history of each test run. When you create a report, you can use the *_live and *_latest view columns to get the latest version of an object.
