abstract={
A critical issue in programming support environments is the data base that stores all project information. This paper presents a model that can be used for analyzing and designing such data bases. The model represents systems as families consisting of multiple versions and configurations. It is based on AND/OR graphs and has the hierachical model, the relational model, and the sequential release model as subclasses.

A refinement of the model yields the concept of the weI/-formed configuration. This concept establishes the basic rules for interface control and system composition. A generalization of the model leads to a data base structure that is a directed, attributed graph. This idea is illustrated by presenting design and implementation of a data base for the sequential release model.},
