7 3 Source and Target Entities

Visual LANSA Logical Modeler

7.3 Source and Target Entities

Relationships are established between two entities. The types of entities determine the type of relationships supported. In addition, the entities must be identified as source and target:

  • The source entity is the entity which is initiating the relationship.
  • The target entity is the object which receives the relationship.

The concept of source and target are determined when the relate connector is linked to the entity. Refer to 7.7.1 Create a Relationship.

For example, Product has a Variation relationship to Manufactured Product. Product is a Data entity and must be the source. Manufactured Product must be a Variant entity and must be the target. The source end of the Relate connector must attached to the Product entity and the target end of the Relate connector must be attached to the Manufactured Product.
