DISTRIBUTED ENVIRONMENT INFORMATION MANAGEMENT SYSTEM

PURPOSE: To control the quantity or definition information to be distributed to improve the response performance of an application system by distributing only definition information at an arbitrary time in a definition information management system. CONSTITUTION: Between a master site 1 and a replica site 2 connected by a network, definition information 19 is copied from a master dictionary 12 to a replica dictionary 16 at an arbitrary time by a master dictionary update report function 13 which reports the definition change and a master dictionary information acquisition function 17 which acquires definition information. Since the dictionary in a master DB 10 is copied to the replica DB site to acquire the latest information at need, the frequency in access to the master DB site through the network is reduced at the time of compilation or execution of an application program, and therefore, the network traffic in the whole of the system is considerably reduced.
