Reference definitions using the model editor

You can define references and choose how they are implemented.

A reference is an entity attribute where the value of the attribute is the identifier of another entity. Creating a reference is similar to creating an attribute or type code.

A reference has the following properties:
  • Name: The name of the reference.
  • Documentation: Optional description of the reference.
  • Documentation URL: Optional URL linking to documentation for the attribute.
  • Nullable: Whether the database column can contain null as value.
  • Reference type: The type of the entity. Click the button to select a type from the available entities.
  • Entity field name: The name of the field in the Entity object class.
  • Database field name: The name of the database column corresponding to this reference.
