The Common Data Model Processor CDMP is a mechanism by which application programs can retrieve and update data without knowing where or how the data are stored. An application program poses requests to the CDMP, which processes those requests against the databases in which the relevant data are stored and then returns the results to tha application program. The Neutral Data Manipulation Language NDML is the means for posing requests to the CDMP. One component of the CDMP, called the NDML Precompiler, generates various programs request processors or RPs, Rp drivers, CS-ES transformers, and locate subroutine callers that are tailored to satisfy the NDML requests in a particular application program. Another component of the CDMP, called the Distributed Request Supervisor DRS, coordinates the operation of these generated programs when they are invoked by the application program at run-time. This development specification describes the functions, performance, environment, interfaces, and design requirements of the Distributed Request Supervisor.
