RETRIEVING SYSTEM USING WWW SERVER

摘要

PROBLEM TO BE SOLVED: To improve the integrity of a system using WWW by executing the access control of a WWW client accessing to a WWW server based on access information. SOLUTION: A user designates a user ID to a WWW server 2 to issue the request of initialization by means of a WWW client 1. The server 2 receiving the request identifies a received user ID and a client ID attached to received data by referring to an identification list 3 and answers the identifying result to the client 1. Then, when the user issues a retrieving request from the client 1, server 2 inspects the user ID and the client ID of the received retrieving request by referring to a using situation list 4 and issues a retrieving request in a designated retrieving formula to a database server 5 to control the access of the client 1.
