Abstract : The Common Data Model Processor (CDMP) is a mechanism by which application programs can retrieve and updata 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 the application program. The Neutral data Manipulation Language (NDML) is the means for posing requests to the CDMP. Some NDML requests involve data that are stored in more than one database. One component of the CDMP, call the Aggregator, combines the data from each of these databases into a complete result for such a request. This development specifications describes the functions, performance, environment, interfaces, and design requirements of the Aggregator.
