Specifies the inverse side of this relationship. Required for relationship properties. Not used for other properties.
To specify the relationship property in the related class that is the inverse of this relationship property, use the following syntax:
Relationship Chapters As Chapter [ Cardinality = cardinality; Inverse = inverse ];
Where inverse is the name of the property in the related class.
This keyword specifies the name of the inverse side of a relationship — that is, the name of the corresponding relationship property in the related class. The inverse property must exist in the related class and have the correct Cardinality value.
The Inverse keyword is required for relationship properties. It is ignored by non-relationship properties.
For more information, see “Defining and Using Relationships” in Defining and Using Classes.
There is no default. When you define a relationship, you must specify the Inverse keyword.
Relationship Chapters As Chapter [ Cardinality = many; inverse = Book ];
