There are several IBM products that contribute to test data management. The most prominent belong to the IBM InfoSphere Optim range of products, including Test Data Management, Data Privacy, Test Data Fabrication and Test Data Orchestrator. These products handle data subsetting and masking, synthetic data generation, and test data coverage. InfoSphere Information Analyzer is also available as a data discovery tool that integrates with the Optim suite. Finally, IBM now provides data virtualisation via InfoSphere Virtual Data Pipeline, a white-label product created by Actifio, a close partner of IBM.
