YYY
YYY is an interactive, graphical tool set for designing databases. Presently it contains tools for the design of the enterprise (conceptual) schema and an expert system for generating the schema for the relational database. On the enterprise level the data model supported in YYY is a variant of the entity-relationship model. A relational database scheme is represented as SQL `create table’-statements. This paper discusses the overall structure of the tool set, the data dictionary, the principles of the user interface and the rules that control the generation of the relational database schema.
