To create a test data warehouse, you create a Test Data Warehouse Service from the Administrator tool. The Test Data Warehouse Service administers the test data warehouse repository and the test data warehouse.

Create and manage data in the test data warehouse from

Test Data Manager

. 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 include 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.

You can publish a

data set

that you create in

Test Data Manager

to the

Test Data Management Self-Service Portal

. Testers who do not have access to

Test Data Manager

can view and restore required test data to a test environment from the

self-service portal

.
