Now in several ways in the context of industrial automation can often be seen in three ways: (1) Programmable Logical Controller (referred to as IPC); (2) Distributed Control System (DCS for short), and (3) t

20、he Programmable Logical Controller (PLC for short). 2.1.2 PLC and the IPC and DCS contrast contrast 1, each of the three technologies of origins and development requirements for fast data processing makes it invented the computer.

27、流就是把客户所购买的商品通过物流配送系统送到客户手中，对于一些特殊行业和领域的电子商城，如证券、金融、信息类商品，也可能不需要配送系统的支持就可以把商品送到客户手中（如股票、电子杂志、网站域名信息等）。1.2电子商城开发的目标开发一套电子商城购物系统，可以让顾客通过浏览器浏览网站货物，选择自己满意的商品，并下订单购买。而网站后台人员需要维护网站会员信息，商品信息以及订单信息等，本系统的目的就是要开发一套既方便顾客网上购物又方便网站维护人员维护网站的WEB服务系统。2.可行性分析随着Internet的发展，电子商城成为21世纪网络发展的主流，网上购物成为一种购物时尚。目前国内企业纷纷加入到阿里巴

28、巴等一系列大型电子商务网站中，通过网路进行交易已经成为商品交易的一种重要组成部分。企业在建立宣传网络的同时，也逐步扩大了企业自身的网络销售渠道，建立起自己的电子商城网站，完成了从“企业到企业”到“企业到个人”同时进行网络交易的过度，大大的提高了企业的生产效益。随着硬件技术、网络技术及网上交易法规的日趋完善，电子商城将成为企业销售经营的主要渠道。2.1经济可行性而经济可行性即成本效益分析，评估项目的开发成本，估算开发成本是否会超过项目预期的全部利润。电子商城在经济上有以下几个突出的优势：1) 资金投资少，回收快，而且无所谓存货，所以特别适合小商店和个人在网上创业。2) 销售时间不受限制，无需专人

29、看守，却可以时时刻刻营业。3) 销售地点不受限制，小商店也可做大生意。4) 网上商店人气旺，网上客流量比较多，只要是商品有特色，经营得法，电子商城每天将为企业额外带来成千上万的客户，大大增加了销售收入。2.2技术可行性分析开发一个中小型的电子商城系统，涉及到的技术问题不会太多，主要用到的技术就是Struts框架。Struts框架是专门用来开发web应用程序的框架，他是采用Java Servlet 和 Jsp技术来构造MVC设计模式。Struts是框架而不是库，但也包括了标签和独立的使用程序类，因此，应用Struts框架开发的Web程序是最佳的选择。3.系统设计3.1系统分析对于典型的数据库管理

30、系统，尤其是像电子商城这样数据流量较大的网络管理系统，必修要满足使用方便。操作灵活等设计需求。电子商城的系统目标如下： 1) 展示网站最新的商品信息，不断地更新商品种类，使用户了解最新的市场动态。2) 网站根据商品的销售情况及厂家信誉度来推荐并展示部分商品。3) 用户可以在网站上修改个人资料、修改个人登录网站密码、查询提交的订单以及查询个人在网站上的消费情况。4) 实现购物车和收银台的功能，用户选择所需要的商品，在线提交商品订单。5) 以循环滚动的方式显示网站公告信息。6) 根据商品的销售情况进行销量排行。7) 展示网站友情链接的图片信息，起到网站之间相互宣传的最用。8) 对商品信息进行管理，

31、选择商品类别将商品具体信息和图片信息都存放在数据库中，并可以修改或者删除商品信息9) 可以查看和查询用详细信息、用户消费信息。10) 对用户提交的订单，根据情况进行阶段处理。11) 对管理员信息、网站公告信息以及友情链接信息进行维护管理。3.2 电子商城系统设计电子商城网站分为前台和后台。其中，根据电子商城前台的特点，可以将其分为商品查询、商品展台、购物车、会员管理、收银台、订单查询、及商城公告7个部分，其中各个部分及其包括的具体功能模块如图3_1展示。图3-1 系统前台模块图根据电子商城后台的特点，可以将其分为友情链接设置。商品大类别设置、商品设置、商品小类别设置、公告设置、后台管理员设置、订单设置以及退出后台9个部分，其中各个部分及其包括的具体功能模块如图3_2所示。图3-1 系统后台模块图3.3业务流程图为了更加清晰的表达系统的业务功能模块，下面给出企业电子书城系统的业务流程图，对于不同的角色，他们所承担的任务各自不同，流程图也不一样。本系统包括向会员的客户端流程图和面向管理员的流程图两部分。面向会员的客户端系统流程图如图3_3所示:图3-3 面向会员的客户端系统流程图面向管理员的流程图如图3_4所示:图3-3 面向管理员的流程图
