When you add a node under AOT > Data Dictionary > Tables > YourTable > Relations, you can set the value of the RelationshipType property of the new relation. The list of possible values for the RelationshipType property is the list of elements in the RelationshipType enum. The meaning of each element in the RelationshipType enum is described in this topic.
The following table describes the elements of the RelationshipType property.
Element name |
Description |
Automatic inference |
NotSpecified |
Often the default value for the RelationshipType property. |
When the RelationshipType property has the value NotSpecified, the system infers an appropriate value. The system infers the value in the following sequence:
For example, if the criteria for both Composition and Aggregation are met, the system infers Composition. This is true because Composition occurs earlier in the list. |
Specialization |
Applies only to table inheritance, to relationships between base and derived tables. |
The system sets the RelationshipType property to Specialization whenever table inheritance is involved. |
Link |
Is a non-relational relationship. Link requires that the Validate property be set to No. This type of relationship supports navigation between forms that list many records from a table and forms that provide detail fields for one record from the table. |
Link is meant only to support the migration of extended data type (EDT) link relations for upgrade to Microsoft Dynamics AX 2012 from earlier versions of the product. Migration tools create this type relationship, but you must not. |
Composition |
Is a stronger type of Aggregation. A table must not have more than oneComposition relation. For example, a building is composed of rooms, and a given room cannot exist in more than one building. |
If the criteria for Composition are met, but you manually assign the value ofAggregation or Association, the system leaves the value as Aggregation orAssociation. |
Aggregation |
Is appropriate when the child table is considered to be subordinate to the entity of the parent table. |
The system infers Aggregation when either of the following is true:
If the criteria for Aggregation are met, but you manually assign the value ofAssociation, the system leaves the value as Association. |
Association |
The concept of a standard foreign key. |
You must set the RelationshipType property to Association if the system does not set the value of property to anything, and both Aggregation and Composition are inappropriate. |
