Abstract

The present invention provides a method, system, and program product for providing proxies for data objects such as SDOs. Specifically, under the present invention, a reference between two data objects is identified. The two data objects could reside in different data graphs, or they could reside in separate branches of a common data graph. In any event, a reference object will be inserter/provided into the branch or data graph containing the reference. The reference object is typically inserted at runtime of an application utilizing the data graph(s), and functions as a proxy for the reference. To this extent, the reference object could be an instance of the data object being referenced, or the reference itself.

Claims

1. A method for providing proxies for data objects, comprising:

obtaining at least one data graph having hierarchically arranged data objects;

identifying a reference from a first data object to a second data object of the at least one data graph; and

providing a reference object in the at least one data graph having the first data object as a proxy for the reference.

2. The method of claim 1, wherein the at least one data graph is a Service Data Object (SDO) data graph, and wherein the first data object and the second data object are SDOs.

3. The method of claim 1, wherein at least one data graph comprises a first data graph and a second data graph, and wherein the first data object resides in the first data graph and the second data object resides in the second data graph.

4. The method of claim 1, wherein at least one data graph comprises a single data graph, and wherein the first data object resides in a first branch of the single data graph and the second data object resides in a second branch of the single data graph.

5. The method of claim 1, further comprising providing an adapter on the at least one data graph to monitor changes to the first data object.

6. The method of claim 1, wherein a relationship between the first data object and the second data object comprises a non-containment relationship.

7. The method of claim 1, wherein the proxy comprises a Boolean proxy.

8. The method of claim 1, wherein the reference object is provided at runtime of an application that utilizes the at least one data graph.

9. The method of claim 1, wherein the method transforms a logical model into a physical model by inserting proxy classes as reference targets, and wherein the reference targets replace original reference targets.

10. A system for providing proxies for Service Data Objects (SDOs), comprising:

a system for obtaining at least one SDO data graph having hierarchically arranged SDOs;

a system for identifying a reference from a first SDO to a SDO of the at least one SDO data graph; and

a system for providing a reference object in the at least one SDO data graph having the first SDO as a proxy for the reference.

11. The system of claim 10, wherein at least one SDO data graph comprises a first SDO data graph and a second SDO data graph, and wherein the first SDO resides in the first SDO data graph and the second SDO resides in the second SDO data graph.

12. The system of claim 10, wherein the reference object comprises an instance of the second SDO.

13. The system of claim 10, wherein the reference object comprises the reference to the second data object.

14. The system of claim 10, further comprising a system for providing an adapter on the at least one SDO data graph to monitor changes to the first SDO.

15. The system of claim 10, wherein the proxy comprises a Boolean proxy.

16. A program product stored on a computer readable medium for providing proxies for data objects, the computer readable medium comprising program code for causing a computer system to perform the following steps:

obtaining at least one data graph having hierarchically arranged data objects;

identifying a reference from a first data object to a second data object of the at least one data graph; and

providing a reference object in the at least one data graph having the first data object as a proxy for the reference.

17. The program product of claim 16, wherein at least one data graph comprises a first data graph and a second data graph, and wherein the first data object resides in the first data graph and the second data object resides in the second data graph.

18. The program product of claim 16, wherein at least one data graph comprises a single data graph, and wherein the first data object resides in a first branch of the single data graph and the second data object resides in a second branch of the single data graph.

19. The program product of claim 16, wherein the computer readable medium further comprises program code for causing the computer system to perform the following step:

providing an adapter on the at least one data graph to monitor changes to the first data object.

21. A method for deploying an application for providing proxies for data objects, comprising:

providing a computer infrastructure being operable to;

obtain at least one data graph having hierarchically arranged data objects;

identify a reference from a first data object to a second data object of the at least one data graph; and

provide a reference object in the at least one data graph having the first data object as a proxy for the reference.
