A data model consists of three parts: (1) a data definition that represents the information in an understandable manner; (2) a definition of the constraints that must hold for the information to be valid; and (3) a definition of operations that can be performed on the information. Current database management systems do not allow explicit specification of all three parts of the data model. This paper gives an approach that extends current database management systems through a technique called pre-precompilation.
