Data Subset™ allows you to define sets of tables to be extracted, add in your own relationships and define selection criteria. Grid-Tools database subsetting software uses native database utilities to migrate the data, allowing you to incorporate the generated scripts into your existing test data management framework.
Data Subset™ can also scramble or mask your data as it is being extracted from production.
