A method and computer program product are provided for implementing pushdown queries in a distributed object management system. A pushdown query to a system datastore is performed for a query type returning a single object. Responsive to the system datastore finding the match, checking whether the match refers to an object changed in the current transaction is performed. Responsive to the match not referring to a changed object, the object is returned. Responsive to the match referring to the changed object and the changed object matching the pushdown query, the changed object is returned. Responsive to the system datastore not finding the match, a list of changed objects in a current transaction is obtained. Each of the changed objects are in a current transactional state. An object query is performed on the changed objects in the list of changed objects. A multiple object pushdown query to the system datastore is performed for a query type returning multiple objects. Then the list of changed objects in the current transaction is obtained and the object query is performed on the changed objects. Results of the multiple object pushdown query and object query are merged and returned.

A class in an object oriented system may be made recyclable by inheriting a recycle.oval-hollow. method from a recyclable class. When automatic garbage collection is attempted on an instance of a class that is recyclable, the garbage collector invokes the recycle.oval-hollow. method on the instance to determine whether or not the instance should be disposed of by the garbage collector. One or more predetermined recycle criteria are used to determine whether a recyclable instance should, in fact, be recycled. If the instance satisfies the recycle criteria, appropriate recycling logic is executed to cause the instance to be recycled, and the garbage collection of the instance is not performed. If, however, the instance is not recyclable, or if it does not satisfy the recycling criteria, it is disposed of by the garbage collector.

The present invention relates to a method of developing a software system using Object Oriented Technology and frameworks for developing a business application. The present invention solves this problem with a framework framework comprising a using non-financial component integration base class, a target financial component integration base class, and a generic data conversion engine. The present invention is applicable in the technical field of application development of software systems, e.g. for a business application as Financial or Logistic and Distribution, wherein it is the purpose of frameworks to provide significant portions of the application that are common across multiple implementations of the application in a general manner, easy to extend for specific implementation.
