Abstract
A computer system for creating a semantic object model from an existing relational database schema. The computer system analyzes the catalog information of the relational database schema and creates a semantic object for each table defined in the catalog. For each column defined within a table, a simple value attribute is added to the semantic object created for the table. The system then analyzes the relationship information stored in the catalog to create object link attributes that define relationships between two or more semantic object as well as to create multivalued group attributes and multivalued, simple value attributes. If the database catalog does not include the relational information, the user is prompted to indicate related semantic objects.
