Abstract
A functionally structured distributed data processing system includes a plurality of independently operating user station processors for servicing users, a data center for storing data to be processed by the user stations, and a communication network for coupling each user station to one or more data centers. The data center includes its own processor and mass storage devices for managing a data base of data for the user stations. Each user station executes application programs to which is linked a data base simulator which formulates requests or data operations to calls to the data base at the data center. Communications between the user stations and the data center are usually initiated only by the user stations.
