Abstract

A method for loading a software application for use at a client node (24, 30) of a network (12, 14) includes activating a program loader system (48) at the client node (24, 30). A user-specific software application setup file (56) is then transmitted from a file server (22, 28) to the client node (24, 30).

Claims

1. A method for loading a software application for use at a client node of a network comprising the steps of:

activating a program loader system at the client node;

transmitting a user-specific software application setup file from a server to the client node, the user-specific software application setup file being associated with a user of the client node and being independent of the particular client node being used by the user; and

loading an application at the client node using the user-specific software application setup file.

2. The method of claim 1 further comprising the steps of:

retrieving existing application data from predetermined locations in a client node data memory; and

storing the existing application data in a prior software data file.

3. The method of claim 2 further comprising the steps of:

retrieving user-specific application data from the user-specific software application setup file; and

storing the user-specific application data to the predetermined locations in the client node data memory.

4. The method of claim 3 further comprising the steps of:

running the software application at the client node; and

modifying the user-specific application data stored at the predetermined locations in the client node data memory while operating the software application.

5. The method of claim 4 further comprising the steps of:

retrieving the modified user-specific application data from the predetermined locations in the client node data memory;

compiling a modified user-specific software application setup file from the modified user-specific application data; and

storing the modified user-specific software application setup file at a server data memory.

6. The method of claim 2 wherein the step of retrieving existing application data comprises the step of retrieving existing application data from predetermined locations in a client node data memory, from predetermined locations in a server data memory, and from predetermined locations from a processor.

7. The method of claim 3 wherein the step of storing the user-specific application data comprises the step of storing the user-specific application data to predetermined locations in a client node data memory, to predetermined locations in a server data memory, and to predetermined locations from a processor.

8. The method of claim 4 wherein the step of modifying the user-specific application data comprises the step of modifying the user-specific application data stored at the predetermined locations in the client node data memory, the server data memory, and the processor while operating the software application.

9. The method of claim 5 wherein the step of storing the modified user-specific software application data file comprises the step of storing the modified user-specific software application data file at the client node data memory and at the server data memory.

22. The method of claim 4, further comprising:

retrieving the existing application data from the prior software data file; and

restoring the existing application data to the predetermined locations in the client node memory.

10. A method for loading a software application for use at a client node of a network comprising the steps of:

activating a program loader system at the client node;

transmitting a user-specific software application setup file from a server to the client node, the user-specific software application setup file being associated with a user of the client node and being independent of the particular client node being used by the user;

retrieving existing application data from predetermined locations in a client node data memory;

storing the existing application data in a prior software data file;

retrieving user-specific application data from the user-specific software application setup file;

storing the user-specific application data to the predetermined locations in the client node data memory; and

running the software application at the client node using the user-specific application data.

11. The method of claim 10 further comprising the steps of:

modifying the user-specific application data stored at the predetermined locations in the client node data memory while operating the software application;

retrieving the modified user-specific application data from the predetermined locations in the client node data memory;

compiling a modified user-specific software application setup file from the modified user-specific application data; and

storing the modified user-specific software application setup file at a server data memory.

12. The method of claim 10 wherein the step of retrieving existing application data comprises the step of retrieving existing application data from predetermined locations in a client node data memory, from predetermined locations in a server data memory, and from predetermined locations from a processor.

13. (Amended) The method of claim 10 wherein the step of storing the user-specific application data comprises the step of storing the user-specific application data to predetermined locations in a client node data memory, to predetermined locations in a server data memory, and to predetermined locations from a processor.

14. The method of claim 11 wherein the step of modifying the user-specific application data comprises the step of modifying the user-specific application data stored at the predetermined locations in the client node data memory, the server data memory, and the processor while operating the software application.

15. The method of claim 11 wherein the step of storing the modified user-specific software application data file comprises the step of storing the modified user-specific software application data file at the client node data memory and at the server data memory.

23. The method of claim 10, further comprising:

retrieving the existing application data from the prior software data file; and

restoring the existing application data to the predetermined locations in the client node memory.

16. A system for loading a software application for use at a client node coupled to a network comprising:

a user-specific software application setup file associated with a user of the client node and being independent of the particular client node being used by the user;

a server having a server data memory, the server coupled to the network and operable to store and retrieve the user-specific software application data file in the data memory;

a program loader system operating on the client node, the program loader system operable to retrieve the user-specific software application data file from the server and to apply parameters from the user-specific software application data file to the client node being used by the user.

17. The system of claim 16 further comprising:

a client data memory; and

wherein the program loader system is further operable to store data from the user-specific software application data file at predetermined locations in the client data memory and the server data memory.

18. The system of claim 16 wherein the user-specific software application data file contains predetermined data and an associated data address.

19. The system of claim 16 further comprising:

a software application system operating on the client node; and

wherein the program loader system is operable to activate the software application system.

20. The system of claim 16 further comprising:

a software application file stored on the server data memory; and

wherein the program loader system is operable to request the software application file from the server and to install the software application file on the client node so as to create a software application system.

21. The system of claim 16 further comprising:

a software application file stored on the client data memory; and

wherein the program loader system is operable to install the software application file from the client data memory so as to create a software application system.
