Our environment is based on a model to describe a project under development. In the model, the materials in a project under development are divided into entities, relationships, and modules. These are represented by a directed graph containing nodes, arcs, and composite objects consisting of collections of nodes and arcs. Subsets of the entities, modules, and relationships can be collected into views. A distinguished base view describes the set of primitive modules of the system being designed and the primitive relationships between the modules and entities. These views provide support for the software tools which are used for the development. The directed graph provides a convenient representation for the project being developed. It has a direct implementation using UNIX files, symbolic links and directories that represent the components of the model. The environment has been implemented on a VAX 11/780 running version 4. 2BSD UNIX operating system, and has been combined with the language-oriented tools of the SAGA system. Only abstract is presented.
