Abstract : This document is the product specification establishing the design implementation of the IISS Configuration Item PRES which will determine a navigational access path through a network database to satisfy a neutral data request. This specification established the design of Function PRE6, Select IS Access Path, 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 select an internal schema access path through a GODASYL database to satisfy an NDML subtransaction request. The following functions will be performed by the CPCI: 1) Determine if a calc key search of the database is possible; 2) Determine if an area sweep of the database is required; and 3) Construct the optimal access path through the database in generic access path specification code terms using data from the internal schema tables.
