C/S模式与B/S模式
一. 什么是C/S模式？
答：C/S （Client/Server，客户机/服务器）模式又称C/S结构，是软件系统体系结构的一种。C/S模式简单地讲就是基于企业内部网络的应用系统。与B/S（Browser/Server，浏览器/服务器）模式相比，C/S模式的应用系统最大的好处是不依赖企业外网环境，即无论企业是否能够上网，都不影响应用。
二.什么是B/S模式？
答：B/S（Browser/Server，浏览器/服务器）模式又称B/S结构。它是随着
Internet技术的兴起，对C/S模式应用的扩展。在这种结构下，用户工作界面是通过IE浏览器来实现的。B/S模式最大的好处是运行维护比较简便，能实现不同的人员，从不同的地点，以不同的接入方式（比如LAN, WAN,Internet/Intranet等）访问和操作共同的数据；最大的缺点是对企业外网环境依赖性太强，由于各种原因引起企业外网中断都会造成系统瘫痪。
Browser/server 模式
服务器端用asp+sql server开发；
客户端用
Internet Explorer
浏览器 / 服务器
三.C/S的实用与缺陷
MIS在我国已有20多年的发展历程， 但真正普及应用还是近十年来的事。由于负责企业庞大而复杂的数据信息的管理,在企业生产经营管理中发挥了巨大的作用，C/S本身也是属于发展到90年代的较为先进的结构。 这种模式将应用一分为二，服务器负责数据管理，客户机完成与用户的交互任务。C/S 具有强壮的数据操纵和事务处理能力，以及数据的安全性和完整性约束。但随着企业规模的日益扩大,应用程序的复杂程度不断提高，逐渐也暴露了以下几点：
1.开发成本较高。C/S 结构对客户端软硬件要求较高，尤其是软件的不断升级，对硬件要求不断提高，增加了整个系统的成本，客户端越来越臃肿。
2.移植困难。不同开发工具开发的应用程序，一般来说互不兼容，不能搬到其它平台上运行。
3.用户界面风格不一,使用繁杂,不利于推广使用。
4.维护复杂，升级麻烦。如果应用程序要升级，必须到现场为客户机一一升级，每个客户机上的应用程序都需维护。
5.信息内容和形式单一，因为传统MIS 一般为事务处理，界面基本遵循数据库的字段解释，开发之初就已确定，而且不能随时截取办公信息和档案等外部信息，用户获得的只是单纯的字符和数字，既枯燥又死板。
6.新技术不能轻易应用。因为一个软件平台及开发工具一旦选定，不可能轻易更改。
四、B/S的先进与不足
基于B/S的Intranet技术，其三项优势是实质性的：
1.它是有计算技术以来最稳定的技术平台。在 C/S时代，用户最苦恼的问题莫过于如何选择一个稳定的平台。由于以前的技术基础不是网络，因此自然地发展出众多的互不兼容的技术平台。每种技术平台，从用户应用稳定性要求来看，都可以说是昙花一现，给用户留下了无奈与苦恼。只有进入网络计算机时代，由于上亿用户都联在网上，其技术才获得了高度稳定性。它只能发展,不能被推翻，所有人只能支持和遵循它,不能控制它。
2.它本质上是一种客户机技术，这对于大中型企业特别合适。在C/S模式下，每种应用的主要部分是在客户机侧。别的不说，光是在众多的客户机侧安装和维护多种应用的多个版本，就叫人受不了。而Internet技术却不同，上亿个用户只是通过浏览器这个统一界面，就可享受到无限丰富的，永远在不断变化和发展着的信息服务。Intranet原则上取消了所有在客户机侧的维护工作。
3.它提供了异种机、异种网、异种应用服务的联机、联网、统一服务的最现实的开放性基础。通过Intranet技术统一访问异种数据库，早已成为现实。从 ISDN 到ATM，再到现在大行其道的TCP/IP，正是由于 Internet的大行其道，宽带IP将会成为真正的、统一服务的（数据、语音、多媒体)网络基础。但是存在着两大问题，一为：企业是一个有结构、有管理、有确定任务的有序实体，而Internet面向的却是一个无序的集合，B/S必须适应并迎合长期C/S下的有序需求方式。其二为：企业中已经积累了或多或少的各种基于非Internet技术上的应用，与这些应用联接，是Intranet一项极其重要而繁重的任务。缺乏对动态页面的支持能力，没有集成有效的数据库处理功能，系统的扩展能力差，安全性难以控制，好集成工具不足等等，都让我们应慎重行事。
