Abstract

A computer-based system for allowing a user to create a relational database schema. The system allows a user to create a semantic object data model of the database schema. The semantic object data model is defined by one or more semantic objects, each of which includes one or more attributes that describe a characteristic of the semantic objects. The attributes are defined as being either simple value attributes that describe a single characteristic of the semantic object; group attributes that include one or more member attributes that collectively describe a characteristic of the semantic object; formula attributes that set forth a computation that describes a characteristic of a semantic object; or object link attributes that define a relationship between two or more semantic objects. Once the semantic object data model is created, the system validates the semantic objects to ensure no modeling errors have been made and transforms the semantic objects and their included attributes into a plurality of relational database tables that will store data as defined by the semantic object data model.
