Integrated Information Support System (IISS). Volume 5. Common Data Model Subsystem. Part 22. Neutral Data Manipulation Language (NDML) Precompiler Build Calls and Messages Product Specification.

摘要

This specification establishes the design of Function PRE10, Build Calls Messages into the Users AP, 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 generate into the User Application process code to assemble tables and parameters needed by both the Distributed Request Supervisor and conceptual to external transformer to satisfy an NDML request. The following functions will be performed by the CPCI: (1) Generate working storage for external schema variables to hold the ES results in the user specified structure or variable, and temporary conceptual schema variables necessary for the transformation; (2) Generate working storage variables to hold the precompile tables namely the Join Query Graph, Attribute Pair List, results table and conceptual schema Action List to satisfy the NDML request; (3) Generate Working Storage and Procedure Division statements for domain and assertion checks; and (4) Generate Procedure Division statements to call the DRS, return with the results and call the conceptual to external transformer and move the ES results into the user variables or structure.
