Abstract

Provided are a method, system, and program for processing a transaction. Transaction data is transmitted from one primary storage site to a plurality of secondary storage sites. A transaction request is received at one secondary storage site and processed to include transaction data from the secondary storage site that was transmitted from the primary storage site. The processed transaction request including transaction data is transmitted from the secondary storage site to the primary storage site to approve the transaction. The transaction request at the primary storage site is approved if the transaction data included in the received transaction request is consistent with the transaction data maintained at the primary storage site.

Claims

1. A method for processing a transaction, comprising:

transmitting transaction data from one primary storage site to a plurality of secondary storage sites;

receiving a transaction request at one secondary storage site;

processing the transaction request at the secondary storage site to include transaction data from the secondary storage site that was transmitted from the primary storage site;

transmitting the processed transaction request including transaction data from the secondary storage site to the primary storage site to approve the transaction; and

approving the transaction request at the primary storage site if the transaction data included in the received transaction request is consistent with the transaction data maintained at the primary storage site.

2. The method of claim 1, further comprising:

receiving the transaction request at the primary storage site;

determining one secondary storage site from the plurality of secondary storage sites; and

redirecting the transaction request to the determined secondary storage site, wherein the redirected transaction request comprises the transaction request received at the secondary storage site.

3. The method of claim 2, wherein determining one secondary storage site from the plurality of secondary storage sites comprises determining one available secondary storage site in closest proximity to a client originating the transaction request.

4. The method of claim 1, wherein the transaction request received at the secondary storage site comprises a request to access resources, further comprising:

determining from the transaction data at the secondary storage site that was transmitted from the primary storage site whether a client originating the transaction request is registered, wherein the transaction request is only processed if the client is registered.

5. The method of claim 1, wherein the transaction request received at the secondary storage site comprises a request to access resources, further comprising:

determining from the transaction data at the secondary storage site that was transmitted from the primary storage site whether the requested resource is available; and

returning a message indicating that the requested resource is not available if the transaction data at the secondary storage site indicates that the requested resource is not available.

6. The method of claim 1, wherein the transaction request received at the secondary storage site comprises a request to purchase a product, further comprising:

determining from the transaction data at the secondary storage site that was transmitted from the primary storage site pricing information for the requested product;

generating at the secondary storage site a response to return to a client originating the transaction request indicating the pricing information for the requested product; and

transmitting the generated response to the client.

7. The method of claim 6, further comprising:

receiving acceptance of the transaction from the client in response to the transmitted response, wherein the processed transaction request including the transaction data is transmitted from the secondary storage site to the primary storage site after receiving acceptance of the transaction from the client.

8. The method of claim 6, further comprising:

processing a payment method for the client after receiving the acceptance of the transaction to obtain approval of payment of the requested product, wherein the transaction request is transmitted to the primary storage after approving the payment.

9. The method of claim 8, wherein approving the transaction request at the primary storage site further comprises:

processing a payment method for the client after receiving the transaction request from the secondary storage site.

10. The method of claim 1, wherein if the transaction request is not approved at the primary site, further comprising:

transmitting from the primary storage site to the secondary storage site transaction data that is not consistent with the corresponding transaction data in the secondary storage site;

generating at the secondary storage site a revised transaction request including data transmitted from the primary storage site that was not consistent in the secondary storage site; and

transmitting the revised transaction request to the client originating the transaction request for approval.

11. The method of claim 1, wherein data transmitted to each secondary storage site is specific to a geographical location including the secondary storage site, such that the secondary storage sites receive different data from the primary storage site.

12. A system for processing a transaction, comprising:

means for transmitting transaction data from one primary storage site to a plurality of secondary storage sites;

means for receiving a transaction request at one secondary storage site;

means for processing the transaction request at the secondary storage site to include transaction data from the secondary storage site that was transmitted from the primary storage site;

means for transmitting the processed transaction request including transaction data from the secondary storage site to the primary storage site to approve the transaction; and

means for approving the transaction request at the primary storage site if the transaction data included in the received transaction request is consistent with the transaction data maintained at the primary storage site.

13. The system of claim 12, further comprising:

means for receiving the transaction request at the primary storage site;

means for determining one secondary storage site from the plurality of secondary storage sites; and

means for redirecting the transaction request to the determined secondary storage site, wherein the redirected transaction request comprises the transaction request received at the secondary storage site.

14. The system of claim 13, wherein the transaction request received at the secondary storage site comprises a request to purchase a product, further comprising:

means for determining from the transaction data at the secondary storage site that was transmitted from the primary storage site pricing information for the requested product;

means for generating at the secondary storage site a response to return to a client originating the transaction request indicating the pricing information for the requested product; and

means for transmitting the generated response to the client.

15. The system of claim 13, further comprising:

means for receiving acceptance of the transaction from the client in response to the transmitted response, wherein the processed transaction request including the transaction data is transmitted from the secondary storage site to the primary storage site after receiving acceptance of the transaction from the client.

16. The system of claim 12, further comprising means for performing if the transaction request is not approved at the primary site the steps of:

transmitting from the primary storage site to the secondary storage site transaction data that is not consistent with the corresponding transaction data in the secondary storage site;

generating at the secondary storage site a revised transaction request including data transmitted from the primary storage site that was not consistent in the secondary storage site; and

transmitting the revised transaction request to the client originating the transaction request for approval.

17. The system of claim 12, wherein data transmitted to each secondary storage site is specific to a geographical location including the secondary storage site, such that the secondary storage sites receive different data from the primary storage site.

18. An article of manufacture including code at a primary storage site and secondary storage sites for processing a transaction, wherein the code causes operations to be performed, the operations comprising:

transmitting transaction data from one primary storage site to a plurality of secondary storage sites;

receiving a transaction request at one secondary storage site;

processing the transaction request at the secondary storage site to include transaction data from the secondary storage site that was transmitted from the primary storage site;

transmitting the processed transaction request including transaction data from the secondary storage site to the primary storage site to approve the transaction; and

approving the transaction request at the primary storage site if the transaction data included in the received transaction request is consistent with the transaction data maintained at the primary storage site.

19. The article of manufacture of claim 18, further comprising:
