1、-Web课程设计-第 29 页Web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

2、、数据库应用、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（3）基于JSP编程（4）开发工具采用Eclipse + DreamWe

3、aver（5）数据库采用ACCESS 2003（6）用户界面友好3.系统流程图：主界面管理员登录会员注册会员登录输入信息输入密码输入密码注册成功查询微博删除微博微博统计查询微博浏览微博微博发布退出数据库设计在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=; b
