Binding Object (Model Designer)
The virtual Binding object contains the information about how an Entity, Attribute, Role, or Inheritance object binds to a physical data source. The Binding object is not used. When Binding is specified, a subtype is used instead.
Entities must be bound to Tables or Columns; Attributes must be bound to Columns; Roles and Inheritances must be bound to Relations.
A Binding object is a reference from the model to an object in the data source view (DSV). The binding object is used by the report server to translate semantic queries into SQL.
