Integrated Information Support System (IISS). Volume 5. Common Data Model Subsystem. Part 7. Neutral Data Definition Language (NDDL) User's Manual

Abstract

The Neutral Data Definition Language, hereafter NDDL, is an interpretive language that was developed to populate and maintain the Common Data Model database (CDM1 Doc. Control No. CCS1 DS 620341000). As the NDDL is intended to be used by data processing professionals who are experts with various database management systems, a discussion of data-base management systems is not included in this document (see CDM Administrators Manual Doc. Control No. UM 620341000). Furthermore, an understanding of the CDM database is necessary. The CDM Database uses a Three-Schema approach based upon The ANSI/X3/SPARC DBMS Framework: Report of the Study Group on Data Base Management Systems. In the IISS, the Three-Schema Architecture is implemented through the CDM facilities to store each of the three types of schemas and the interschema mappings. The NDDL supports the population and maintenance of appropriate representations for each of the three types of schemas.
