1、Web课程设计docWeb课程设计课程设计报告书 设计题目 micro blog信息系统 专业班级 xxxxx 学号姓名 xxxxxxxxx 指导老师 xxxxxxx设计日期 xxxx 年x月x日 前言Micro blog信息系统主要是一个校园微博系统，在该系统中可以注册、登录，同时还分普通会员登录及管理员登录。通过登录后，可实现发布、查询、删除微博等各项功能。关键字：信息系统 微博 登录系统分析1.设计目的：1综合应用java程序设计、WEB程序设计、数据库应用、计算机网络等知识设计和实现我校Micro Blog信息系统。2通过上述设计和实现，加深对java程序设计、WEB程序设计、数据库应

2、用、计算机网络相关理论的理解，锻炼综合应用所学知识分析问题和解决问题的能力。3培养软件开发的团队协作精神。系统设计1.设计内容：（1）用户注册（2）用户登录（分一般用户和管理员）（3）某用户发布微博信息（4）浏览所有用户的微博信息（5）浏览指定用户的微博信息（6）查询某些用户或（且）某时间段或（且）某论题的微博信息。（7）删除某些用户或（且）某时间段或（且）某论题的微博信息。（8）统计分析某时间段的用户数量，微博数量。（9）发布重大消息或提示信息（7-9基于管理员）2.设计环境：（1）完整实现设计内容所指定的功能（2）应用服务器采用Tomcat 6.0或以上（3）基于JSP编程（4）开发工具采

3、用Eclipse + DreamWeaver（5）数据库采用ACCESS 2003（6）用户界面友好3.系统流程图：数据库设计在Micro blog信息系统中，共设计3张表。本系统使用Access来创建数据表。数据库的名称为WEB.mdb,三张表分别为admin、message、user。表：admin表：message表：user系统实现代码Login.javapackage mybean.data;public class Login String logname, password, backNews=; boolean success=false; public void setLog
