Editing data models

You can edit a data model when you want to modify or delete its components.

About this task

You can edit a data model with Ecore editor in any of the following ways:
  • Renaming an entity, attribute, or reference.
  • Moving an attribute between entities. An attribute can be moved from one entity to another.
  • Moving a reference between entities.
  • Modifying the type and cardinality of a reference.
  • Merging two attributes of an entity.
  • Deleting an entity, attribute, or reference. If you delete an entity, any stored instance data for that entity is also deleted. If you delete an attribute or a reference, all data for that attribute or reference is deleted from instances of the entity that contains that attribute or reference.
