Abstract

The disclosure generally describes methods, software, and systems, including a method for defining and using dependencies and equivalences for data elements in the data model in order to improve query efficiency. At design time of a data model, dependencies and equivalences for data elements in the data model are received over a computer network. The dependencies and equivalences are stored in persistent storage with the data model. A request is received over the computer network, the request to be executed to obtain results from a database associated with the data model. An optimized query is generated using the received request and the dependencies and equivalences. The optimized query is optimized relative to the received request.
