Abstract
A method, system, and computer program product for reducing dependency calculation time in object persistence with circular referential integrity dependency is provided. The method includes building a graph using foreign key dependency from object to relational mapping, where nodes of the graph are object types and connected directionally from a source containing a foreign key to a target of a foreign key reference. The method further includes topologically sorting the graph to order dependencies among the nodes including circular dependences. The method also includes encapsulating the circular dependencies as a complex node. Furthermore, the method includes performing object dependency calculations on the nodes and the complex node in the graph. The results of the object dependency calculations are used to generate a sequence in which the objects can be modified in a relational database.
