摘要
OCI是Oracle9i数据库为应用系统开发人员提供的数据库开发接口,传统的基于OCI的数据库访问应用程序存在通用性差、资源占用率高、访问权限控制不灵活等缺点。基于OCI的数据库访问中间件是一种基于服务的中间件产品,它不仅具有封装性、可重用性、位置透明性等服务程序的特性,还很好地解决了上述问题。同时,文章给出了两组实验,通过实验数据对两种技术的性能进行了分析比较。
OCI is the interface of database development that Oracle9i database provides to the applied system developer. The traditional method has such problems as low generality, high rate of resources usage, and unavailability of convenient access authority control. The database access middleware based on OCI is a kind of middleware based on service. It not only has such service procedure characteristics as encapsulation, heavy use, and position transparency but also resolvs the above problems. At the same time, this paper carries out two experiments through the data of which to compare the performance of two kinds of technology.
