摘要
The present invention is a computer based system that allows a user to create a relational database schema. The system allows the user to create a semantic object data model of the database schema. Semantics An object data model is defined by one or more semantic objects, each of which contains one or more attributes that describe the characteristics of the semantic object. Attribute is a simple value attribute that describes a single characteristic of a semantic object; A group attribute containing one or more member attributes collectively describing characteristics of the semantic object; A mathematical property that performs calculations describing the characteristics of the semantic object; Or an object connection attribute that defines a relationship between two or more semantic objects. If a semantic object data model is created, the system verifies the semantic object to ensure that there is no modeling semantics, and the semantic object and its associated attributes are stored in a plurality of relationships Transform it into a database table.
