 * **Migration Job**: A Migration Job displays the state or a given Migration execution, either for validation or migration purposes. A job consists of a number of sequential phases, users can opt to wait after a given phase for user input to resume with the following phase.
 * **Database Connection**: A Database Connection represents information about a source or target database, such as connection details and authentication credentials. DMS uses the OCI Vault to store credentials. A Database Connection is reusable across multiple Migrations.
