Procedure language access to proposed American national standard database management systems

Network and relational database standards are under development by technical committee X3H2 of the American National Standards Institute. This paper is an overview of the procedure language interface to these proposed standards. It introduces the basic structures and operations of each data model, focuses on the procedure language interface as a facility for database access from external languages, and discusses various alternatives for use of the database language standard with existing standard programming languages. The paper contains example application programs of each access alternative and concludes with a discussion of basic requirements for application of the standard specifications to distributed database processing in an open systems environment.
