基于JSP的WEB数据库动态技术构建某市供热公司在线收费系统

Net Online Charging System of Dynamic Web Database Technology Based on JSP

随着互联网的发展和全球经济一体化，电子商务的建设变得非常重要。近年来，网络的迅猛发展给人们生活带来很大的便利．也使得企业向着信息化的方向发展。同时，企业的需求也带来了Web开发技术的更新。Web技术和数据库技术互相结合．产生了Web数据库。Web数据库结合了Web技术和数据库技术的优点，它使Web网页从静态网页发展成了由数据库驱动的动态网页．同时数据库系统的开发环境和应用环境也实现了分离，提高了代码的可重用性、灵活性以及软件的性能和可维护性。JSP具有开放性、功能强大、跨平台等众多优点，它所定义的三层B／S体系结构很适合于构造网络缴费平台。该文利用TSP／Servlet技术，结合MVC设计模式，开发了基于Web的利用JSP／Servlet技术的三层架构网上缴费信息系统的解决方案。该方案实现了表示层和逻辑层的分离，该收费系统实现了原有系统的全部功能，能很好的替代原有收费系统，并且在扩展性和执行的效率上有了提高，更好的适应了收费业务的发展。

With the development of the Internet and global economic integration, the building of e-commerce is very important recent years, with the development of Internet technical, the network brings more and more conveniences to people＇s living in every aspect and also urges the informational development of the enterprise. At the same time the need of the business also promotes the web develop technical renewal. Therefore, people put the Web technology and the database technology together, which lead to the appearance of the WebDatabase technology. Combing the advantage of Web technology and database technology, the Web pages change into dynamic epages, which are driven by database, and the development enviroment can be separated from the using environment. It separates the view and the business logic forcibly, so it improves the reusability, agility of the code and the quality and maintainability of software using the framework. JSP has many advantages of opening, mighty function and cross-platform. The three-layer B/S system construction based on JSP is adopted to constructing net online charging platform. Then it is essential to developing Net Online Charging System of dynamic web technology based on JSP. Technology of JSP/Servlet and model of MVC are used in this paper, a structure of net charging system of dynamic web-database technology based on JSP is presented. This charging system realizes all the functions of the former system, primely substitutes the former system, and improves the expansibility and the efficiency of execution, adapts the development of the business well.
