Integrating Database, Spreadsheet, Graphics, GIS, Statistics, Simulation Models and Expert Systems: Experiences with the RAISON System on Microcomputers

The Raison system is a fully integrated database, spreadsheet and graphic interpretive system with GIS and expert systems capabilities for PC/AT microcomputers. It is used as a toolkit that links internal programming functions with external files from popular software. With customization facility for special application, RAISON provides an intelligent interface between model and data, as well as descriptive dialogue between human and machine. The salient features in this system are briefly described, with emphasis on the interactions among its subsystems and external files. Case studies are provided to illustrate its use. A future plan for improvement is discussed.
