Abstract

This paper describes how a general purpose programming language supporting the notion of data abstraction can be used as a data definition and manipulation language for database management systems. The examples used here are based on a functional data model and on a database system called NDB. However, the approach is not limited to or biased towards any particular data model or architecture. The strong typing properties of the data abstraction language are carried over to the realm of database manipulation operations and provide useful consistency checking. The advantage of the approach is that the user deals with but one database programming language, thereby avoiding a separate query and host language.
