Design of data management for real-time database in processing industry
Cheng Wang · Journal of Zhejiang University(Engineering Science) · 2003
The processing industry's realtime database has s pecial a pplication background. The data model theory of realtime database and data cha racteristics of the processing industry is first studied. Then by employing t he latest information technology, a new design method for data management of the processi ng indu stry's realtime database is presented for the processing enterprises' applicat ion of realtime database. In the data model, data from the processing enterprise is o rganized by tag mapping technology. The model has a fast query system with multi layer indexing structure by using STL(standard template library). In addition , the data model support distributed computation in the processing enterprises b y adopt ing COM/DCOM (distributed component object model) technology. The validity and f easibility of the presented design method were proved by the method's succ essful application in the realtime database software of APCiSYS.
