The architecture of a rule-based expert system for logical database design which uses descriptions of business forms as its primary method of requirements specification is described. The system incrementally builds a conceptual schema through analysis of a collection of forms. The analysis of individual forms is based on the properties of form fields such as their hierarchical structure, origin, and relative position on the form. Form analysis rules are applied in a forward direction against a base of facts consisting of form descriptions, an evolving conceptual of facts consisting of form descriptions, an evolving conceptual schema, and a design history. Some of the form analysis rules prompt the designer for missing information and confirmation.
