In Data Management Service (DMS), you can apply for the permissions to query or submit tickets to modify or export data in a database, table, or column. After the corresponding owner approves your application, you can perform the applied operation.
- Query: the permission to run SQL statements in SQLConsole to query data of the object on which you want to apply for the permission.
- Export: the permission to submit tickets to export data of the object on which you want to apply for the permission. Note that you cannot export data without approval.
- Modify: the permission to submit a data change ticket or a database and table synchronization ticket. Note that you cannot change data without approval.

In DMS, you can customize different approval processes for databases and tables as required. For example:
- Define a strict process for approving operations on databases and tables related to the core business and data in the production environment.
- Define a simple process for approving operations on data related to edge business or in the test environment. You can even allow managing such data without approval.
