| Abstract: | In the construction of the real-time monitoring system for industrial control source, the design of the real-time database is introduced. Aiming at the trait of RTDBS, it analyses and realizes the key technologys such as function modules, store structure, transaction scheduling and concurrency control. It improves the stability and hard real-time property of the system using memory-mapped files, multi-thread technology, multimedia timer and synchronous object. |
