Web技术在股票查询系统中的应用及Java实现

Application of Web Technology in a Stock Query System and Realization with Java

随着网络技术的飞速发展和电子商务的兴起 ,数据库在Internet/Intranet条件下发生了巨大改变 ,在数据库的访问、数据共享和数据发布方式等方面均有较大发展。利用Java语言的跨平台性、强大的网络通讯功能及数据库互联能力等特点 ,开发出一个具有良好扩展性的基于Web的股票查询系统 ,提出一种三层结构的Web数据库解决方案。用户通过浏览器发出查询请求 ,服务器程序接受请求并与后台数据库进行通讯 ,然后将结果返回。数据库中某一时刻某一股票发生变化 ,触发器触发调用扩展存储进程 ,通过命名管道进入Java服务器。

With the development of Web technology and the coming of electronic business, database technologies such as database accessing, data sharing and data dissemination has been changed greatly under Internet/Intranet environment.This paper introduce mainly the design and implementation of a query system of stock based on Web. It has been developed by using Java's platform spanability, strong network communication and the ability of database linking. A three level solution of database on Web has been brought forward. Users can send out their querys by explorer, server receives them and communicates with database. If sometimes a stock changes, trigger will call extend storage processor, then commited to Java server by named pipeline.
