数据访问中间件研究

Research on Data Access Middleware

数据访问中间件是在分布式系统中建立数据应用资源互操作的模式,实现异构环境下的数据库连接或文件系统连接的中间件,该类中间件在所有中间件中是应用最广泛、技术最成熟的一种。全面而系统地介绍了数据访问中间件的研究工作、实现机制及关键技术。对数据访问中间件进行了展望,指出了数据访问中间件的未来发展方向。

Data Access Middleware is a middleware which establishes a model of data application resource interoperation and implements database link or file system link under heterogeneous environment in a distributed system. This kind of middleware is one of most popular and maturest middlewares. This paper comprehensively introduces the research efforts, implementation mechanism and key techniques of data access middleware. Finally, the future direction of data access middleware is indicated.
