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...
Formal specification languages and methods for refining specifications into programs have, up to now, received more attention than methods for obtaining the initial formal specification. This situation is corrected in the ESPRIT project METEOR, which distinguishes the two activities of requirements engineering (RE) — obtaining the right specification — and design engineering (DE) — using that specification...
This paper relates an experiment in writing an algebraic specification of a rather complex example, namely a subset of the UNIX file system. The PLUSS specification language, which is used for this experiment, provides a set of linguistic features which allow the modularization of such specifications and the definition of a flexible and convenient syntax for expressions and axioms (such as mixfix...
