Test Data Management (TDM) is the process of provisioning data for development and testing in preproduction environments. It ensures efficient, high-quality datasets while safeguarding data privacy and sensitive corporate information to meet compliance and security requirements. Modern TDM solutions leverage synthetic data generation, alongside data subsetting and masking techniques, to provide realistic yet secure test data. These solutions are widely used by software developers, QA engineers, data analysts, and IT security teams to optimize testing, maintain regulatory compliance, and enhance application reliability.
