ABSTRACT:
An object model comprises one or more semantic objects that represent items about which data is stored in a relational database in a computer system. Each semantic object has one or more components that define the data stored for each item. The object model is mapped into a current relational database schema. As a user makes changes to the model the computer system generates a proposed relational database schema, and the differences between the current relational database schema and the proposed relational database schema are determined. The relation database is modified to reflect changes made in the corresponding object model based upon the differences between the current and proposed relational database schemas.
