AOP在数据访问中间件中的应用

AOP:APPLICATION IN DATA ACCESS MIDDLEWARE

在开发数据访问中间件中 ,分布式应用开发是难以避免的。本文运用AOP(Aspect OrientedProgramming)建立一种框架执行分布式 ,并运用于图书馆统一检索平台中。使用AOP的思想在于通过分离关注点 ,降低中间件开发的难度和复杂度。而且 ,系统拥有更好的模块化、可扩展性和可维护性。

In developing Data Access Middleware,distributed applications are not avoidalble.In this paper we discuss a frame to deal with distributed applications by use AOP(Aspect Oriented Programming),and apply the frame into searches platform in library.The fundamental idea behind AOP is that it should be possible to create programs that crosscut each other.It can reduce difficulty and complexity in developing middleware.Furthermore,software system has advancement in modularity,expansibility and maintenance.
