Abstract
A method of transforming queries based upon an entity/relationship schema into multi-dimensional expression queries is provided. The method comprises matching an object referenced in an entity/relationship schema based report specification to a corresponding object in the entity/relationship schema, the corresponding object adorned with associated multidimensional metadata; adding the associated multi-dimensional metadata to the object referenced in the entity/relationship schema based report specification; translating the entity/relationship schema based report specification into a multi-dimensional expression query; and retrieving directly all data required to populate a report output of the entity/relationship schema report specification.
