摘　　要：信息化时代,数据增长迅速,形式多样,数据的存储安全和高效处理问题备受关注,传统的关系数据库因其单表架构和行存储特点读写速度慢、扩展性较差,难以适应大数据的存储。关系与非关系数据库的融合技术应运而生。文中提出一种面向隐私保护的异构数据库集成中间件系统,虚拟化集成关系与非关系数据库。该中间件系统通过明密文数据库的整体映射,实现对隐私数据的保护,且其加解密过程对上层应用透明;通过提供通用的基于标准的体系结构,实现允许用户以SQL语句统一操作密文数据库和非关系数据库。仿真结果表明,该中间件系统中密文数据库保证了数据的安全性,关系与非关系数据库的融合可以存储和处理海量数据,SQL统一操作的标准化框架提高了系统的扩展性和应用范围。In the information age,data is growing rapidly with various forms.Data storage security and efficient processing issues have attracted much attention.Traditional relational databases have slow read and write speeds and poor scalability due to their single-table architecture and row storage characteristics,which is difficult to adapt to big data.The fusion technology of relational and non-relational databases came into being.A heterogeneous database integration middleware system for privacy protection is proposed for virtualization of integration relationship and non-relational database.The middleware system realizes the protection of the private data through the overall mapping of the ciphertext database,and the encryption and decryption process is transparent to the upper layer application.By providing a general standards-based architecture,the user is allowed to uniformly operate the ciphertext database and non-relational databases by using the SQL statement.The simulation shows that the ciphertext database in the middleware system guarantees the security of data.The fusion of relational and non-relational databases can store and process massive data.The standardized framework of SQL unified operation improves the scalability and application scope of the system.
