OBJECT-RELATIONAL MAPPING FOR TABLES WITHOUT PRIMARY KEYS

摘要

Methods and systems consistent with the present invention provide an improved object-relational mapping tool used to maintain information in relational database tables that do not utilize primary keys. The improved object-relational mapping tool uses a cursor update operation associated with relational database tables to maintain information contained in a relational database table without primary keys, including performing operations such as, delete or update on the table.
