Development of a Query Processor for a Back-End Multiprocessor Relational Database Computer.

A Query Processor for a back-end multiprocessor relational database computer has been defined. An existing high level design for the proposed database computer was used to define the context, and that proposal was reviewed. An abstraction of the original proposal was developed so that a more general design approach could be taken. A requirements analysis for the query processor was performed. This analysis was carried to the lowest level possible without fixing any implementation details. Flexibility in defining the data manipulation language was obtained. A general design is presented that should be applicable to the development of a prototype of the entire database computer. The general nature of this design should make the concept very portable. The interfaces to the rest of the computer have been segregated into four modules to minimize the changes needed for portability. (Author)
