【摘要】 为解决Saa S平台面临的数据安全及分布式数据管理等问题,提出了基于开放架构的Saa S服务平台系统应用框架;在此基础上,对数据应用进行了抽象建模,以优化缓存管理策略的思路解决网络环境下的数据访问问题。通过将传统LRU算法与SIZE算法相结合,提出了LRU-RSIZE算法,对开放Saa S服务平台的数据访问进行管理,并进行仿真分析。开放Saa S服务架构与LRU-RSIZE算法相结合,可有效地解决用户数据的按需存储与管理问题,并对增强用户的应用体验具有重要的意义。更多还原

【Abstract】 To solve the problems of data security and distributed data management that existed in Saa S platform, the paper puts forward a system application framework based on open Saa S service platform architecture. On the basis of this architecture, the paper gives abstract modeling on data application, which uses the idea of optimizing cache management strategy to solve data access problem in network environment. Combining with traditional LRU arithmetic and SIZE arithmetic, the paper gives a LRU-SIZE arithmetic which is effective on the management of data access of the open Saa S service platform. The combination of open Saa S service architecture and LRU-SIZE arithmetic can solve the problems of data access and data management of enterprise effectively. Meanwhile, it can improve the application experience of users.更多还原
