Abstract: Enterprise systems, methods and computer program products are disclosed for providing bulk create (insert), update and delete operations for table inheritance in an enterprise resource system using an object-oriented language supporting polymorphism. The computer implemented method comprises receiving a request for one of a create, update and delete operation with respect to data of first and second tables of an inheritance table hierarchy; creating a temporary table comprising a surrogate key and a record identifier; establishing a filter condition with fields from different tables in table inheritance; and one of creating, updating and deleting data from the different tables in table inheritance according to the filter condition. The process is implemented on an application object server including a compiler for the object-oriented language, a kernel instance and a data access layer.
