Web Service is the core of the next generation programmable network, by defining the Web Service that can query test scores, not only we can achieve to query test scores by online way, if it have been published and registered, the system can also realize to share data resources on the database server, others can search WSDL of the Web Service and call the Web methods that provides by the Web Service of this system without having to write a implementation code to realize accessing data resource of the database server in this system, which can reduce the duplication of code to write, save resources; also by searching the relevant Web Service that have been published and registered on the Internet, we can realize to integrate the remote data in the system through its reference, accordingly to achieve the shared services on the Internet environment.%Web Service是下一代可编程网络的核心,通过定义实现考试成绩查询功能的Web Service,不仅可以实现考试成绩的在线查询,如果对其进行发布和注册,还能够实现系统数据库服务器上数据资源的共享,使得别人可以根据搜索到的该系统Web Service的WSDL,方便地调用系统Web Service提供的Web方法,而不需编写实现代码就能够实现对系统数据库服务器上数据资源的访问,由此可以减少代码的重复编写,节省资源；也可以通过搜索Internet上已发布和注册的相关Web Service,通过对其引用实现异地数据在本系统中的集成,从而实现整个互联网环境上的服务共享.
