【Abstract】 The strategy and procedure of designed a real-time database system (RTDBS) with dynamic-link library are introduced. A method of sharing main memory database in multiprocess by means of memory-mapping file in dynamic-link library (DLL) is presented, and of realizing application program interface (API) of RTDB, data compression, memory-based history database and disk-based history database is also given. Thus established RTDBS possesses good openness.更多还原
