A lab group is a database that is created in the underlying parent database that is selected when a lab group is created. A child database is created in the underlying Lab Group database when an add lab request is approved.
The actions in the portlet affect the Teradata Database privileges or accessibility on the underlying Lab databases as listed below.
| Action in the Portlet | Privileges or Accessibility on the Lab Database |
|---|---|
| When a lab expires | READ and WRITE commands cannot be performed. |
| When a lab is reinstated | READ and WRITE commands can be performed. |
| When a lab is deleted | A DROP command is performed. |
| When a Teradata Database user or role is made read-only | Users can only issue SELECT statements, but not other DML statements or DDL. This prevents users or roles from creating, modifying, or dropping Teradata Database tables in a lab. |
| After a lab extension is approved on an expired lab | The lab owner gets access to the Lab database. |
