摘　　要：为解决离线应用系统中本地数据数据存储问题,设计与实现一个以开源数据库SQLite为底层存储的数据存储方案。针对开源SQLite数据库只支持明文存储的不足,提供了两种可选的加密解密算法,并研究和评估了这两种不同的加密解密算法对数据存储效率的影响。在实现本地数据存储层的基础上,提出了一种实用的数据存储模型,以方便离线应用结构化数据的存取。To solve the problem of local data storage in offline application system, a data storage solution using open source database SQLite as the underlying storage is designed and implemented.To overcome shortcomings of only supporting cleartext storage for the open source database SQLite, two optional encrypt and decrypt algorithms is presented and the storing and retrieving efficiency of the two different algorithms is studied and evaluated.Meanwhile a new practical data storage model based on this local data storage layer for easily storing and retrieving the structural data of offline application is put forward.
