基于Android系统的学生成绩查询系统设计

Student score search system based on Android system

设计并实现了基于Android系统的学生成绩查询系统手机客户端软件。该查询系统结合SQLite数据库和学院网络学生成绩查询系统,采用C/S模式,其后台服务器使用数据库服务器和应用服务器组成的双重服务架构,这不但便于管理,还能提高服务响应速度。其中数据库服务器主要通过API获取学生成绩数据,应用服务器则是针对取到的学生成绩数据进行解析以及重新组装,以xml格式反馈给手机客户端,手机客户端进行DOM数据解析后,即可显示到用户界面。服务器端采用Servlet技术,在Eclipse平台下使用JAVA语言编程完成学生本年度成绩及历年成绩查询功能。实际测试表明,系统可运行于基于Android系统的移动设备,且运行稳定、查询便捷、适用性强。

Mobile phone student score search system based on Android system is realized in this paper.It combines the SQL database with the Institute Web Student Score Search System,use the C/S mode,and its background server uses the database server and the application server to constitute the dual service structure,this not only makes the management easier but also enhances the response speed.Database server gets student data through API,application server analyzes the data,reassembles it and feedbacks to the phone as xml format,then mobile client will display after DOM data analysis.With Servlet in server,use JAVA under Eclipse platform,this mobile phone system can search student score of this year and before.Tests show clearly that this system can be used on whichever mobile device based on Android system,it performs stable,convenient and strong applicability.
