ABSTRACT:
A method executed by a computer system for converting a database schema in relational form to a schema in object-oriented (00) form. The input is the schema of a database in relational form including all relations of the schema and the primary keys, reference keys, and attributes of each relation. A special data structure (SDS) is created for each primary key based on the number of attributes of the key. Each SDS becomes the basis of an object of the 00 schema produced. Attribute functions and cross-reference functions are created based on the SDSs and reference keys. SQL commands to map the relational input schema to the 00 output schema are identified.
