Organizations create multiple copies of application data to use for testing and development. Organizations often maintain strict controls on production systems, but data security in nonproduction systems is not as secure. An organization must maintain knowledge of the sensitive data in production systems and ensure that sensitive data does not appear in the test environment. Development must not have to rewrite code to create test data.

With TDM, an organization can create a smaller copy of the production data and mask the sensitive data. An organization can discover the sensitive columns in the test data and ensure that the sensitive columns are masked in the test data. An organization can also create test data that does not contain sensitive data from the production database.

Manage data subset and data masking in Test Data Manager. Use data subset to create a small environment for testing and development. You can define the type of data that you want to include in the subset database. You might create a subset database with data based on time, function, or geographic location. Create data masking rules to apply to source columns and data domains. You can assign multiple rules to the same column.

To perform data subset and masking operations, you can generate and run workflows from data subset and data masking plans in Test Data Manager.

TDM users have roles and privileges that determine the tasks they can perform through Test Data Manager. The administrator manages roles and privileges for users from the Informatica Administrator.
