Data warehouse system is a system providing remote queries for multiple providers and transmitting data via World Wide Web. This system has three parts: the client, the provider and the virtual data processor. The client (respectively, the provider) transmits the data into the virtual data processor, and the provider (respectively, the client) retrieves the data from the virtual data processor unit when the data are required. The client (respectively, the provider) can also transmit the data directly to the provider (respectively, the client) via the virtual data processor. Since the client contacts with only one corresponding unit of the provider, the gap between the client and provider is reduced. It also increases operation efficiency and reduces costs.
