摘要

Systems, methods and computer program products automatically order database transaction by an object-oriented transaction system. The objects in the completed transaction are clustered into groups of objects to be inserted into the relational database, objects to be deleted from the relational database and objects to be updated in the relational database. The objects to be inserted into the relational database are ordered according to an insert precedence of the objects into the relational database to thereby define an insert order. The objects to be deleted from the relational database are ordered according to a delete precedence of the objects from the relational database are ordered according to a delete precedence of the objects from the relational database to thereby define a delete order. The objects to be inserted into the relational database are inserted into the relational database in the insert order. Then, the objects to be updated in the relational database are updated in an arbitrary order. Finally, the objects to be deleted from the relational database are deleted from the relational database in the delete order.
