An approach for creating automated tools for database design is outlined. PROEX, a knowledgebased system for the conceptual and logical design stages, is presented. The system has as its main goal the provision of an interactive methodological environment for relational database design. It employs a semantic data model. PROEX accepts a description (possibly incomplete) of the modelled slice of reality (universe of discourse), constructs a conceptual schema and then attempts to produce some form of computer processible relational database schema. The embedded design methodology and the overall architecture of the system are discussed.
