(2)进入系统友界面清晰分企业信息理企业电信息理两选择
(3)点击企业信息理拉菜单中选项实现企业信息查询添加修改删操作
(4)点击企业电理信息拉菜单中选项实现企业电理信息查询添加修改删操作
(5)系统客户端运行Windows台服务器运行WindowsUnix台系统应该较图形户界面
(6)系统应该扩展性
2需求分析
需求分析客户需求中提取出软件系统够帮助户解决业务问题通户业务问题分析确定系统功需求步骤理解需求升华直接关系该系统质量分析根目开发者提出需求间建立种理解沟通机制系统需求分析应该开发员户客户起完成
22 性规定
1精度
精度需求根需项数输入输出传输程中满足种精度需求：根关键字精度查找分精确查找泛型查找精确查找精确匹配系统者知道企业名称编号快速便捷查询知道信息
2时间特性求
软件方面响应时间更新处理时间较快迅速完全满足户求
3灵活性
户需求操作方式运行环境结果精度数结构软件接口等发生变化时设计软件做适调整灵活性非常
22 数需求分析

6 收获体会
次课程设计心体会通实践收获：
开始接触数结构课程设计真挺难会逻辑方面问题具备动手力脑子里总团火题目开始想法想逻辑实现编写程序需编写开始难说知道里入手参考书里程序仿结构步步做现单链表种操作已算较熟练知道光理知识远远够需动手写然手擒
二根实中遇问题学程中注意点：
1认真专业实验课实践中锻炼
2写程序程中考虑周严密
3做设计时候信心耐心切勿浮躁
4认真学课知识掌握课中知识点基础学会灵活运
5课余时间里写程序熟练掌握调试程序程中遇常见错误便节省调试程序时间

企业电理系统设计
1 课题容求
11课题描述
系统设计信息：
（1） 电企业（电企业编号电企业名址电话联系）
（2） 电费信息（谷价峰价）
（3） 电情况（电企业编号谷电量峰电量年月年合计电量年合计电费）
12 课题求
求够进行操作：
（1） 够统计电企业月耗电量电费
（2） 够统计查询电企业总谷电量峰电量
（3） 够统计该区峰谷电量例电费情况
（4） 维护基数
（5） 户分级理机界面良
2 需求分析
21 功规定
1理解需求
理解需求问题终解决方案间架设桥梁第步开发者户充分理解需求开始设计系统否需求定义改进设计必须量返工
面系统终端户客户调研需求规格说明书
(1)者相关电力部门学系统开始时便进入欢迎界面
(2)进入系统友界面清晰分企业信息理企业电信息理两选择
(3)点击企业信息理拉菜单中选项实现企业信息查询添加修改删操作
(4)点击企业电理信息拉菜单中选项实现企业电理信息查询添加修改删操作
(5)系统客户端运行Windows台服务器运行WindowsUnix台系统应该较图形户界面
(6)系统应该扩展性
2需求分析
需求分析客户需求中提取出软件系统够帮助户解决业务问题通户业务问题分析确定系统功需求步骤理解需求升华直接关系该系统质量分析根目开发者提出需求间建立种理解沟通机制系统需求分析应该开发员户客户起完成
22 性规定
1精度
精度需求根需项数输入输出传输程中满足种精度需求：根关键字精度查找分精确查找泛型查找精确查找精确匹配系统者知道企业名称编号快速便捷查询知道信息
2时间特性求
软件方面响应时间更新处理时间较快迅速完全满足户求
3灵活性
户需求操作方式运行环境结果精度数结构软件接口等发生变化时设计软件做适调整灵活性非常
22 数需求分析
数字典
（1）factory
名称：factory
名：
描述：企业基信息
组成：factory（num+facname+repname+tel+usefnum+usegnum+usemoney）
(2) worker
名称：worker
名：
描述：员工理员基信息
组成：worker（id+workername+password+level）
3 系统设计
31 功模块设计
32 数库概念设计
321实体属性图
322 ER图
33 数库逻辑设计
企业（编号企业名法代表）

5 代码调试功测试
51 测试方案
（1）分输入户理员查登陆进界面
（2）分户理员查询企业电信息
（3）添加企业电信息
（4）修改企业电信息
（5）删企业电信息
（6）生成电费单
52 测试结果
理员登陆
理员登陆界面
理员登陆查询界面
户登陆查询界面
点击添加界面
输入数
添加成功
点击修改进行修改信息
修改成功
点击删出现界面
删成功
点击生成电费单出现界面
桌面生成电费单
6 收获体会
次课程设计心体会通实践收获：
开始接触数结构课程设计真挺难会逻辑方面问题具备动手力脑子里总团火题目开始想法想逻辑实现编写程序需编写开始难说知道里入手参考书里程序仿结构步步做现单链表种操作已算较熟练知道光理知识远远够需动手写然手擒
二根实中遇问题学程中注意点：
1认真专业实验课实践中锻炼
2写程序程中考虑周严密
3做设计时候信心耐心切勿浮躁
4认真学课知识掌握课中知识点基础学会灵活运
5课余时间里写程序熟练掌握调试程序程中遇常见错误便节省调试程序时间
