public abstract class MdmModel
extends MdmObject
implements Model

A Model that assigns a value to an MdmAttribute or an MdmMeasure for a set of MdmDimension members. The values and the MdmDimension members are specified by the Assignment or MdmAssignment objects of the MdmModel.

An Assignment is associated with a Source. An Assignment is transient and exists on the client only for the duration of the session. Oracle OLAP applies the assignment when executing a query.

An MdmAssignment is associated with an Expression. An MdmAssignment persists on the server. Oracle OLAP adds the assignment to the MdmModel and writes it to the server when the application commits the transaction.

Assignment, MdmAssignment
