Abstract
An information service providing system using a network comprises a terminal group, an information processing center, and various types of databases. When a portable terminal transmits the category of information service and the retrieval condition data to the information processing center, the center selects the necessary database on the basis of the category of service and searches the databases selected in a chain reaction manner using a retrieval result as the next retrieval condition so as to fulfill the retrieval conditions. Then, the center outputs the retrieval results of the databases to the terminal.
