Integrated Information Support System (IISS). Volume 5. Common Data Model Subsystem. Part 15. Neutral Data Manipulation Language (NDML) Precompiler Decomposition Conceptual Schema NDML Request Product Specification
M.L. Apicella, J. Slaton, Benjamin Lévi · 1990
This specification establishes the design of function PRE5, decompose CS NDML, one of the major functions of the configuration item precompiler to be built and formally accepted by the ICAM program office. This CI constitutes one of the subsystems of the common data model processor (CDMP). The purpose of this computer program configuration item (CPCI) is to break down a CS NDML transaction, or request, into its various CS NDML subtransactions. The following functions will be performed by this CPCI: (1) Map all CS attribute use classes, entity classes and relation classes; (2) Identify all unions, intra database joins, inter database joins and unions and not in set operators; (3) Reformat the original request into single database subtransactions; and (4) Control further code generation of request processors.
