Method and system for presenting on-line Yellow Pages particularly in association with location data

摘要

A method for doing business, wherein a web server maintains a commercial subscriber database including a plurality of records each containing data relating to commercial subscribers including at least name, address and category, and imposes a periodic subscription fee on at least some of said commercial subscribers. On receiving from a client machine connected thereto a request to download data relating to at least one specified category of commercial subscriber, it extracts from the commercial subscriber database respective records and sends to the client machine for display thereby, allows receipt of an update from one or more commercial subscribers in respect of substitute or supplementary data to that contained in the respective database record of the commercial subscribers, and updates the commercial subscriber database as required. The web server may check whether a client machine is on-line and has extracted data from the respective database record of one or more commercial subscribers, and if so uploads to the client machine the update in respect of each of the commercial subscribers for display on the client machine.
