A Back-end Computer for Data Base Management.

It is proposed that the data base management function be placed on a dedicated back-end computer which accepts commands (in a relatively high level language such as the CODASYL Data Base Task Group, April 1971 Report) from a host computer, accesses the data base on secondary storage, and returns results. The advantages of such a configuration are discussed An experimental implementation, called the experimental Data Management System, XDMS, is described and certain conclusions about the back-end approach are drawn from this implementation.
