Design of an Integrated Software System Based on the Relational Data Base Model.

Integration of application programs into a single system has become increasingly important as the workstation environment moves toward uniformity for easier learning and use. This thesis proposes an Integrated Software System ISS based on the Relational Database model as a suitable basis for integrating five common applications found in a business office. Relations, or tables, are defined as the common data objects and it is shown how they are used to support each logical application. Operations based on relational algebra are defined which extend the functions of ISS beyond the aggregate of the five chosen applications. A simple graphical user interface is designed for the kernel of the system and a design for a kernel prototype using a Unix environment is presented. Author
