摘要
介绍华北石化公司实时数据库系统的体系结构,重点讨论实时数据的存储与压缩。在开发与实施实时数据管理系统的过程中,采取面向对象的存储方式和改进的旋转门数据压缩算法,并利用数据平滑技术对测量噪声进行抑制。
The real time database architecture of North China Petrochemical Branch Office is introduced.The accessing and compressing of real time data are discussed emphatically.In the process of developing and implementing data management system,object based access mode and advanced Swinging Door data compress algorithm are adopted and using data smoothing technology to control measurement noise.
