delete the definition of an entity type

  1. In the Data Modeler: Initial Screen enter the name of the entity type in the entry field Modeling object.
  2. Select Entity type under Selection.
  3. Click on Change.
  4. Choose Entity type ® Delete in the screen Maintain Entity Type: Definition. A pop-up window appears.
  5. In the Delete entity type pop-up, confirm that you wish to delete the entity type by selecting Yes. The remaining procedure varies according to whether or not references and/or dependent objects exist:

No references or dependent objects exist

If there are no references (occurrences in data models, relationships, and so on) or dependent objects (such as directly assigned attributes) for this entity type, it will now be deleted. The system returns you to the initial screen and a message stating that the entity type has been deleted is output in the status line.

References exist

If references still exist for this entity type, a list of these will be output. You cannot delete an entity type until you have deleted all its references.

The procedure is as follows:

    • Double-click on the name of the first reference. The relevant screen

in which you can delete the reference appears.

    • Delete the reference.
    • Click on Back to return to the list of references.
    • Delete all the references.

Once all the references have been deleted, the entity type will itself be deleted, provided no dependent objects exist.

If dependent objects still exist, a list of these will be output.

Dependent objects exist

If the entity type to be deleted has dependent objects, a list of these will be output.

If you wish to delete the entity type with its dependent objects, choose Delete in this screen. The system returns you to the initial screen and a message stating that the entity type has been deleted is output in the status line.
