Abstract
Abstract: Among the design issues for symbolic computation systems, a non trivial one is the design of the database where informations (specifications, proofs, test sets, program modules, etc.) that are necessary to use the various tools available are stored. In this paper we address the design of a database for an algebraic specification environment, and provide an algebraic specification for this database management. One of the issues in this design is to distinguish between “static” aspects, i.e. the attribute updating that is necessary to preserve the database consistency when a single action takes place, and the “dynamic” aspects, that take into account the management of concurrent accesses to the database. The specification language modularity was crucial in order to correctly specify such notions as “coherent list of attributes”, “coherent list of modules”, etc. Since various cases of attribute dependencies were studied (transitive dependence of a given module attributes, and dependence w.r.t. other module attributes), the specification may be easily modified to take into account modifications in the environment architecture (when new tools are added, some new attributes may be necessary). In the same way, this specification could be adapted to specify other symbolic computation systems database management. Due to lack of space the extension of the specified database to the dynamic one is not given here, but this extension is a further argument to demonstrate the feasability and interest of our approach.
