transmitting the main program revision level to the remote computer; and

replacing the remote program revision level stored in the remote memory with the main program revision level.

4. The method of claim 1, wherein the revision level is an integer.

5. The method of claim 1, wherein the revision level provides an indication of the program files changed on the main computer.

6. The method of claim 1, wherein the revision level provides an indication of data files changed in the memory of the main computer.

7. The method of claim 1, further comprising transmitting data from the main computer to the remote computer when the program corresponding to the serial number stored in the remote memory is determined to be valid during the detecting step.

8. The method of claim 7, wherein the data is transmitted from the main computer in an update file.

9. The method of claim 7, wherein the data is electronic catalog data related to at least one product.

10. The method of claim 1, wherein the denying step denies access to data stored in the memory of the main computer for all programs having the same invalid serial number.

11. The method of claim 1, wherein the main computer is a single computer.

12. A method for detecting pirated copies of a software program located on a remote computer including a remote memory for storing a program, a remote revision level, and a program serial number from a main computer including a main memory for storing the program serial number, the remote revision level corresponding to the program serial number, and a validation code for a remote program corresponding to the serial number, the validation code indicating whether the program stored in the remote memory is valid or invalid, the method comprising the steps of:

receiving at the main computer the remote revision level and the program serial number stored in the remote memory from the remote computer;

comparing the remote program revision level received from the remote computer to the remote program revision level corresponding to the program serial number received from the remote computer stored in the main memory;

changing the validation code to indicate the serial number is invalid upon detection during the comparing step of a difference between the remote program revision level received from the remote computer and the remote program revision level stored in the memory of the main computer corresponding to the program serial number received from the remote computer;

detecting whether the program stored in the remote memory is valid or invalid based upon the validation code corresponding to the program serial number received from the remote computer; and

denying access to data stored in the memory of the main computer when the program corresponding to the serial number stored in the remote memory is invalid.

13. The method of claim 12, further comprising the steps of:

storing product data related to a plurality of products in a memory of the main computer;

transmitting a first subset of product data related to a plurality of products from the main computer to the remote computer for storage in the remote memory of the remote computer; and

receiving a data request query related to at least one selected product at the main computer from the remote computer.

14. The method of claim 13, further comprising the steps of:

executing the data request query at the main computer to generate a second subset of product data related to the selected product from the data stored in the memory of the main computer; and

transmitting the second subset of product data from the main computer to the remote computer.

15. The method of claim 14, further comprising the step of transmitting a map from the main computer to the remote computer along with the second subset of product data to instruct the remote computer in the integration of the first and second subsets of product data.

16. The method of claim 12, further comprising:

storing the latest revisions of the program and a main program revision level in the memory of the main computer;

determining updated portions of the program stored in the main computer that are different from the program stored in the remote computer; and

transmitting the updated portions from the main computer to the remote computer to permit replacing portions of the program stored in the memory of the remote computer with the updated portions received from the main computer.

17. The method of claim 16, further comprising:

replacing the remote program revision level corresponding to the program serial number stored in the main memory with the main program revision level after the updated portions of the program are transmitted to the remote computer;

transmitting the main program revision level to the remote computer; and

replacing the remote program revision level stored in the remote memory with the main program revision level.

18. The method of claim 12, wherein the revision level is an integer.

19. The method of claim 12, wherein the revision level provides an indication of the program files changed on the main computer.

20. The method of claim 12, wherein the revision level provides an indication of data files changed in the memory of the main computer.

21. The method of claim 12, further comprising transmitting data from the main computer to the remote computer when the program corresponding to the serial number stored in the remote memory is determined to be valid during the detecting step.
