ABSTRACT:
Provided are a main-memory resident object-relational database management system (ORDBMS) and a method of deleting a class instance using the ORDBMS. The method includes obtaining a mutual exclusive lock for a class to be deleted as per the query and a child class inheriting from the class when a query of deleting an instance is input from a database access application program, and deleting the instance from the class and at least one instance related to the instance from its child class using OID reference.
