Abstract
If the recent DBMS technologies consider the problem of databases schema evolution, standard Information Systems in use raise hard problems when evolution is concerned. This paper studies these problems in the current developer context. It analyzes the evolution of systems and its impact on the data structures, data and programs through typical strategies. The paper introduces the DB-MAIN CASE environment with which an evolution tool prototype has been developed. This tool can automatically generate the conversion programs for the database from the operational trace of the conceptual and logical schema modifications. It can also help the programmer to modify the application programs.
