Create and manage the test data warehouse from Test Data Manager. To create a test data warehouse, you configure a test data warehouse repository and a test data warehouse.
Data is stored as data sets in the test data warehouse. The test data warehouse repository stores the project metadata and the source table metadata associated with the data set. Project metadata includes the plan information, version, and tag information. The test data warehouse stores the source data that you included in the data set.
You can create multiple versions of a data set to maintain different versions of the test data. To return a test environment to a previous state, you can choose to restore a specific version of the data from the test data warehouse.
For example, before you run any test cases, you create a data set to store the original test data in the test data warehouse. After each team runs its tests and the data is modified, each team creates another version of the data set to store the modified test data. To return the test environment to its original state, you can restore the version of the data set that contains the original data. You can retrieve any of the other data set versions to return a test environment to a required state.
