基于B/S结构的信息查询通用数据模型

Information-querying general data model based on B/S structure

采用JAVA技术,设计开发了基于B/S(浏览器/服务器)网络模式的信息查询通用数据模型。在遵循Model-View-Controller(MVC)设计模式的基础上,建立信息查询流程。同时对关系型数据库的概念和操作进行抽象、封装、继承,建立对象化数据库模型。文中还通过XML实现了数据属性映射。文中建立的数据模型具有跨平台性、数据库无关性、通用性、可伸缩性等特点,可显著提高系统的开发效率和运行可靠性。

Based on B/S (browser/server) network pattern and JAVA technology, an information-querying general data model is proposed in this paper. In accordance with Model-View-Controller design pattern, the information-querying flow is formulated. Moreover, an object-oriented database model is established by the abstraction, encapsulation and inheritance of the database's conception and operation. Besides, the mapping of the data's attributes is realized by XML file. The data model has the features of platform-independence, DBMS-independence, generalization and scalability, and can remarkably improve the developing efficiency and reliability.
