The Realization of CIM Data Access Mechanism Based on FastDB

摘要

FastDB is an open source real-time database with characteristics of high efficiency and the object oriented, supporting the various object-oriented, running on different operating system platform, convenient for realizing CIM data access mechanism. Through the analysis of CIM data access mechanism, this paper states the methods of the resources location, data query, data describing in the process of data access. The realization code, the function and exception handling methods of CIM data access interface ResourcelDService, ResourceQueryService code based on FastDB are given. FastDB can effectively use CPU cycles and memory, to some extent, meet real-time requirements of the system on the data, and increase the development, maintenance efficiency of the whole system in the different industries.
