PURPOSE: A middle ware system for integrating a multi database and accessing method for integrating distribution different types local database using the system are provided to use as a lower basement structure by offering a middle layer capable of accessing and integrating a plurality of different types databases as a single interface. CONSTITUTION: An integration server(41) has a multi-threaded multi server with shared memory system structure. Information needed to be shared between servers is maintained through a shared memory(42), and the information may be used simultaneously. A request broker(43) renders a client(46) to be connected with the integration server(41). A master(44) is a processor connecting the integration server(41) to all sorts of agency process(45). The agent process(45) performs a query demand with respect to a local database(LDB) instead of the integration server(41). The client receives wanted query language and transmits to the integration server(41), and transmits a result transmitted from the integration server(41) to a user.
