Abstract:
1. A method, comprising: in a runtime environment of a computing system, accessing a data field of a first object to retrieve a backward reference to a second object, the two objects representing items of persistent data and are in a unidirectional relationship in an object oriented relational database wherein the second object points to the first object, further wherein the backward reference does not interfere with the relational database scheme; storing the backward reference in a memory of the computing system; removing the unidirectional relationship from the memory of the computer system by calling a container persistence management function, by which a persistent management of entity beans associated with a container in which the first and the second objects reside is managed; deleting the first object by calling a container persistence management function, by which the persistent management of entity beans associated with the container in which the first object resides is managed; and cascade deleting the second object by accessing the data field of the first object to identify the second object based on the backward reference stored in the data field in the memory of the computing system.
