PROPOSAL FOR AN INTERFACE SYSTEM BETWEEN BUSINESS AND DATA-PROCESSING SYSTEMS

Presentation of a new concept called the application controller which addresses some DPS/end user interface problems. It is a new way to see business activities, DPS activities and user/DPS interactions and is a proposal for a software package. The aim of the application controller is to involve the end user in the definition and design of his application to a high extent and to base DPS and user activities on a model of the application. This model accommodated in the application controller describes the application to the user and to the DPS not only during system analysis and design, but during the operation of the DPS as well. The application controller thus adds to the existing modes of DPS's, namely batch and real time, the state triggered DPS.
