A publish and subscribe system and method for ISP data delivery comprises two parts, a subscription part and a data content update part. In the subscription part, a client file is created with records for which data content packages are desired, and the file is sent to the ISP. The ISP creates a file with the requested data and the client integrates this file into its environment. The ISP maintains a record of the requested data. In the data content update part, changes to the relevant data content packages are recognized by the ISP, and an update file is sent to the client. This update file includes only those records that reflect changes since the previous update. |
