软件工程实验报告——超市运营管理系统面向对象设计
1．概述
面向对象设计就是将面向对象分析的问题域分析模型转换为符合成本和质量的求解域设计模型。该阶段再划分为系统设计和对象设计。系统设计确定实现系统的策略，进行系统架构设计、人机界面设计、数据设计和模块设计；对象设计确定设计模型中的类、关联、接口和现实服务的算法。面向对象设计与面向对象分析是一个多次反复迭代的过程，二者界限模糊。
2．系统结构设计
选课系统整体上采用Internet技术，客户端通过Web方式进行信息的发布和获取。软件架构采用浏览器/服务器方式。客户端采用JavaScript、Java等网络编程语言编写，其脚本程序简单易用、灵活性强，可以控制整个Web页面。基于JavaScript的用户界面为用户所熟悉，因此，我们选择JavaScript来编写基于HTML的客户端应用程序，完成客户与服务器间的参数传递，在浏览器中解释执行。设计时考虑访问权限，对不同权限级别显示相应的内容。Web网络服务器向用户提供业务服务，应用服务器处理Web服务器转发的请求进行业务处理。我们基于SQL Server 2005数据库平台搭建选课系统数据库。
本系统采用面向对象的三层体系结构，这种三层体系结果是在客户端与数据库之间加入了一个中间层，应用程序将业务规则、数据访问、合法性校验等工作放到了中间层进行处理。通常情况下，客户端不直接与数据库进行交互，而是通过COM/DCOM通信与中间层建立连接，再经由中间层与数据库进行交换。三层结构包含：表示层、业务逻辑层、数据访问层。
3．模块及人机界面设计
超市管理系统有5个人执行者和3个系统执行者，即“系统管理员”、“顾客”、“销售人员”、 “前台客服人员”、“超市经理”、“财务管理系统”、“采购管理系统”、“库存管理系统”。
1）系统管理员：负责整个软件的维护工作，可以添加用户，并对用户设置权限。 2）顾客：顾客购买商品，并可以在前台客服办理会员，成为会员，便可以在客服处查询购物情况。还可以在客服处兑换积分。
3）销售人员：销售商品，对商品进行管理。
4）前台客服人员：服务于顾客，为顾客办理会员，兑换积分。
5）超市经理：监督超市的整个运营情况，可以查询销售情况，作出决策。 6）财务管理系统：根据销售汇总情况核对财务状况。 7）采购管理系统：根据销售情况，制定采购计划。

本系统开发的目的是实现在线远程给教师分配课程和学生注册课程，以提高工作效率，所以系统的人机交互界面都是以Web页面形式呈现。下面给出主要的功能界面和设计说明。
