The Study and Design of the Industrial Real-time Database System Huang shao-chuan1，KAI Jin-yu2, Mo Lin3 (1、Guangxi international business vocational college ,Guangxi Nanning 530007； 2、College of Computer and Information ,Anyang Normal University, Henan Anyang 455000 3．Guangxi University, Guangxi Nanning 530004) Abstract: In order to improve the level of combination of the managing and controlling in the enterprises, reflect uniformly the real time running states of all spots in the enterprise, the design of an industrial real time database is the key of combining the industrial scenes net and managing net. The strategy of designing a real-time database system (RTDBS) with VC++ and Delphi are introduced, a method of establishing RTDBS by means of dynamic link library (DLL) is presented, and a method for realizing model and interface is given, a new method of saving multi-times history data by using cycling mechanism for saving memory space is introduced. Thus RTDBS designed in Industry possesses all-round openness and flexibility.
