System for retrieving coexisting data

PURPOSE: To provide a coexisting data retrieval system equipped with a coexisting function, and to provide a method for constructing the coexisting data retrieval system from a conventional data retrieval system. CONSTITUTION: This system is provided with a data server 10 for retrieving a data object 16 from a data storage part 14, and relating means for relating the retrieved data object with a virtual place. A user 17 who performs access to the retrieved data object can coexist with the virtual place. This method for constructing a coexisting data retrieval system by upgrading a conventional data retrieval system having the data storage part 14, data server 10, and plural data retrieval clients includes a process for applying a coexisting server 20, and a process for obtaining 'coexisting' data retrieval clients 22 by adding necessary functions to the data retrieval clients.
