文档介绍：ChRDB: A High Performance RTDB System with Object-Oriented Data Representation Architecture JIN Shu, BAO De-mei, JIA Zhi-min Guodian Nanjing Automation . Jiangsu Nanjing 210003, E-MAIL: jinshu@ , ******@sac- Abstract : To improve the flexibility and extensibility of traditional RTDB systems, which adopt field-specific ways of data representation that always leads to customized development whenever requirements changes, ChRDB manages all the data, both system dependent and project specific, in an object-oriented st yle. Customized types of data objects and corresponding instance s can be easily created to satisfy any project-specific requireme nts newly devised. With the ke rnel module optimized in the platform-dependent level and wrapped into a uniform abstraction level, ChRDB can be ported to all the main-stream operation systems, including Windows and major UNIX variants. With the help of the performance adaptive mechanism that are driven by the puting platform and the real-time responsiveness evaluation of c lient processes, ChRDB achieves high performance and availability as proved by both the simulation results and real-world operations.
