graphic and relational data base support for problem solving
This paper describes a general purpose 'picture building system'. The main purpose of the system is to provide an environment wherein an application programmer can interactively create and modify applications. In addition to a graphics software package the picture building system provides high-level application building tools and a relational data base as integral parts of the system. An interpreter is provided to draw pictures from data stored in relations. A correlation handler is provided to allow a user to identify and manipulate displayed items. A relations editor is provided to interactively create, edit, and display relations. The picture building system works on a variety of graphic and nongraphic terminals.
