Abstract

A store of interfaced software objects are distributed between a server computer and multiple client computers to support an object oriented application communication environment that provides communication between multiple software applications. The application communication environment may include a central shared object store of interfaced software objects that operate on a server computer and communicate with one or more software applications on the server computer. A local shared object store of interfaced software objects operates on each client computer and communicates with the central shared object store and one or more software applications on that client computer. Changes to interfaced software objects in the local shared object stores are automatically and dynamically propagated to the interfaced software objects in the central shared object store. A local private object store of interfaced software objects operate on each client computer and communicate with one or more software applications on the client computer.

Claims

1. In a networked computer system having a server computer in communication with plural client computers, an application communication environment with persistent object stores, comprising:

a central shared object store of interfaced software objects that operate on the server computer and communicate with one or more software applications on the server computer;

a local shared object store of interfaced software objects that operate on each client computer and communicate with the central shared object store and one or more software applications on the client computer, communications between the one or more software applications and the local shared object store on each client being available to the central shared object store; and

a local private object store of interfaced software objects that operate on each client computer and communicate with one or more software applications on the client computer, communications between the one or more software applications and the local private object stores on each client computer not being directly available to the central shared object store, the local private object store on at least one client computer adapted to communicate with the local shared object store on the at least one client computer.

2. The system of claim 1 in which ones of the interfaced software objects of each local shared object store are instances of the interfaced software objects of central shared object store.

3. The system of claim 1 in which the central shared object store maintains a complete and centralized representation of the interfaced software objects that are shared by the local shared object stores.

4. The system of claim 1 in which changes to interfaced software objects in the local shared object stores are automatically and dynamically propagated to the interfaced software objects in the central shared object store.

5. The system of claim 1 in which the communication between the shared and private local object stores includes passing private information from the private local object store to the shared local object store.

6. The system of claim 1 in which the interfaced software objects in the central shared object store and the local shared object store provide communication between users of the client computers.

7. The system of claim 1 in which the local private shared object stores, the local shared object stores, and the central shared object store have generally the same operation and structure.

8. In a networked computer system having a server computer in communication with plural client computers, an application communication environment with object stores, comprising:

a central shared object store of interfaced software objects that operate on the server computer and communicate with plural software applications on the server computer;

a local shared object store of interfaced software objects that operate on each client computer and communicate with the central shared object store and plural software applications on the client computer, communications between the software applications and the local shared object store on each client being available to the central shared object store; and

a local private object store of interfaced software objects that operate on each client computer and communicate with plural software applications on the client computer, communications between the software applications and the local private object store on each client computer not being directly available to the central shared object store, in which the local private object store on at least one client computer communicates with the local shared object store on the at least one client computer.

9. The system of claim 8 in which the interfaced software objects of each local shared object store are instances of the interfaced software objects of the central shared object store.

10. The system of claim 8 in which the central shared object store maintains a complete and centralized representation of the interfaced software objects of the local shared object store on each client computer.

11. The system of claim 8 in which changes to interfaced software objects in the local shared object store are automatically and dynamically propagated to the interfaced software objects in the central shared object store.

12. The system of claim 8 in which the interfaced software objects in the central shared object store and the local shared object store provide communication between users of the client computers.

13. In a networked computer system having a server computer in communication with plural client computers, an application communication method, comprising:

maintaining on the server computer a central shared object store of interfaced software objects that communicate with plural software applications on the server computer;

maintaining on each client computer a local shared object store of interfaced software objects that communicate with the central shared object store and plural software applications on the client computer, communications between the software applications and the local shared object store on each client being available to the central shared object store;

maintaining on each client computer a local private object store of interfaced software objects that communicate with one or more software applications on the client computer, communications between the one or more software applications and the local private object stores on each client computer not being directly available to the central shared object store; and

providing communication between the local private object store and the local shared object store on at least one client computer.

14. The method of claim 13 further comprising maintaining in the central shared object store a complete and centralized representation of the interfaced software objects of the local shared object store.

15. The method of claim 13 further comprising automatically and dynamically propagating to the interfaced software objects in the central shared object store changes to interfaced software objects in the local shared object store.

16. The method of claim 13 in which the interfaced software objects in the shared object store and the local shared object store provide communication between users of the client computers.

17. A computer readable medium having computer executable instructions for performing steps for communicating information in a network of computers having a server computer and a plurality of client computers, the steps comprising:

(a) maintaining a central shared object store of interfaced software objects that operate on the server computer;

(b) maintaining a local shared object store of interfaced software objects on each client computer, the interfaced software objects of the local shared object store operating on the client computer and including at least a portion of the interfaced software objects of the central shared object store;

(c) propagating changes to the interfaced software objects in the local shared object store to the central shared object store;

(d) maintaining a local private object store of interfaced software objects on each at least one client computer, the interfaced software objects of the local private object store operating on the at least one client computer; and

(e) propagating filtered status information of the interfaced software objects of the local private object store to the central shared object store.

18. The computer readable medium of claim 17, wherein propagating filtered status information includes propagating the filtered status information to the central shared object store through the local shared object store.

19. In a networked computer system having a server computer in communication with plural client computers, an application communication environment with persistent object stores, comprising:

a central shared object store of interfaced software objects that operate on each client computer and communicate with the one or more software applications on the client computer;

a local shared object store of interfaced software objects that operate on each client computer and communicate with the one or more software applications on the client computer;

at least one first application on each client computer which propagates to the central shared object store changes in the interfaced software objects of the local shared object store on each client;

a local private object store of interfaced software objects that operate on at least one client computer and communicate with one or more software applications on the at least one client computer; and

at least one second application on the at least one client computer which propagates to the central shared object store filtered status information of the interfaced software objects of the local private object store.
