第二篇:BS100字英文介绍
B/S模式
一、介绍
B/S模式是一种以Web技术为基础的新型的管理信息系统(简称MIS)系统平台模式。把传统C/S模式中的服务器部分分解为一个数据服务器与一个或多个应用服务器(Web服务器),从而构成一个三层结构的客户服务器体系。
第一层客户机,它是用户与整个系统的接口。客户的应用程序精简到一个通用的浏览器软件,如Netscape Navigator,微软公司的IE等。浏览器将HTML代码转化成图文并茂的网页。网页还具备一定的交互功能,允许用户在网页提供的申请表上输入信息提交给后台,并提出处理请求。这个后台就是第二层的Web服务器。
第二层Web服务器将启动相应的进程来响应这一请求,并动态生成一串HTML代码,其中嵌入处理的结果,返回给客户机的浏览器。如果客户机提交的请求包括数据的存取,Web服务器还需与数据库服务器协同完成这一处理工作。第三层数据库服务器的任务类似于C/S模式,负责协调不同的Web服务器发出的SQ请求,管理数据库。
二、B/S和C/S的区别
1.硬件环境不同:
C/S 一般建立在专用的网络上,小范围里的网络环境,局域网之间再通过专门服务器提供连接和数据交换服务。
B/S 建立在广域网之上的,不必是专门的网络硬件环境,例如电话上网,租用设备.信息自己管理.有比C/S更强的适应范围,一般只要有操作系统和浏览器就行。
2.对安全要求不同
C/S 一般面向相对固定的用户群,对信息安全的控制能力很强。一般高度机密的信息系统采用C/S 结构适宜。可以通过B/S发布部分可公开信息。
B/S 建立在广域网之上,对安全的控制能力相对弱,可能面向不可知的用户。
3.对程序架构不同
C/S 程序可以更加注重流程,可以对权限多层次校验,对系统运行速度可以较少考虑。
B/S 对安全以及访问速度的多重的考虑,建立在需要更加优化的基础之上.比C/S有更高的要求 B/S结构的程序架构是发展的趋势,从MS的.Net系列的BizTalk 2000 Exchange 2000等,全面支持网络的构件搭建的系统。SUN 和IBM推JavaBean 构件技术等,使 B/S更加成熟.。
4.软件重用不同
C/S 程序可以不可避免的整体性考虑,构件的重用性不如在B/S要求下的构件的重用性好。
B/S 对的多重结构,要求构件相对独立的功能.能够相对较好的重用.就如买来的餐桌可以再利用,而不是做在墙上的石头桌子
5.系统维护不同
C/S 程序由于整体性,必须整体考察,处理出现的问题以及系统升级.升级难.可能是再做一个全新的系统
B/S 构件组成,方面构件个别的更换,实现系统的无缝升级.系统维护开销减到最小.用户从网上自己下载安装就可以实现升级。
6.处理问题不同
C/S 程序可以处理用户面固定,并且在相同区域,安全要求高,需求与操作系统相关.应该都是相同的系统。
B/S 建立在广域网上,面向不同的用户群,分散地域,这是C/S无法作到的。与操作系统平台关系最小。
7.用户接口不同
C/S 多是建立的Window平台上,表现方法有限,对程序员普遍要求较高。B/S 建立在浏览器上,有更加丰富和生动的表现方式与用户交流.并且大部分难度减低,减低开发成本。
8.信息流不同
C/S 程序一般是典型的中央集权的机械式处理,交互性相对低。
B/S 信息流向可变化,B-B B-C B-G等信息、流向的变化,更像交易中心。
三、B/S的优点
1、系统开发、维护、升级方便
每当服务器应用程序升级时,只要在服务器上升级服务应用程序即可,用户计算机上的浏览器软件不需要修改,系统开发和升级维护方便.2、B/S模式具有很强的开放性
在B/S模式下,用户通过通用的浏览器进行访问,系统开放性好。
3、B/S模式的结构易于扩展
由于Web的平台无关性,B/S模式的结构可以任意扩展,可以从包含一台服务器和几个用户的小型系统扩展成为拥有成千上万个用户的大型系统.。
4、用户使用方便
B/S模式的应用软件都是基于Web浏览器的,而Web浏览器的界面是类似的。对于无用户交换功能的页面。用户接触的界面都是一致的,用户使用方便。
TopicofB / S structure
Ⅰ.Introduction
B/S is a new pattern information managementsystem(MIS)of platform model , which is based of Web skill and break up the server part of traditional C/S model into a data server and no less than one application server(web server),so that become client system with three structures.The first tier client, it is the interface between the user and the system.Streamline client application to a generic browser software such as Netscape Navigator, Microsoft's IE and so on.Browser HTML code into the illustrated pages.Site also has some interactive features that allow the user to enter information presented to provide background on the web application form and make processing the request.The second layer is the background Web server.The second layer of the Web server will initiate the process to respond to this request, and dynamically generate a bunch of HTML code, the result of which is embedded processing, returned to the client browser.If the request submitted by the client includes a data access, Web server, and database server needs to complete the collaborative processing.The third layer is the database server tasks similar to C/S mode, responsible for coordinating the SQ different Web server sends requests, manage the database.Ⅱ Difference between B / S and C/S
(1)Hardware environment
C/S is generally built on a dedicated network, a small range in the network environment, then provide connectivity and data exchange services between the LAN via a dedicated server.B/S builds on the wide area network, the network does not have to be a dedicated hardware environment, such as telephone access, leased equipment.Information they manage.Than the C/S stronger adaptation, generally as long as the operating systems and browsers on the line.(2)Safety requirements
Relatively fixed C/S is generally user-oriented group of information security controls are strong.Generally highly confidential information systems using C/S structure appropriate.It can publish public information through B/S.B / S based on the wide area network, the security control is relatively weak, the user may for unknown.(3)Program Structure
C/S programs can pay more attention to the process, you can check on the multi-level privileges on the system speed can be less consideration.B/S for security and access speed of multiple considerations, the need to establish more optimal basis.Has higher requirements B/S structure of the application architecture is the development trend of the ratio C/S, from the MS.Net Series the BizTalk 2000 Exchange 2000, a comprehensive support network components to build a system.SUN and IBM push JavaBean component technology, so that B/S is more mature.(4)Software reuse
C/S integrity of the program can be considered unavoidable, reusable component reuse is not as good in B/S requirements under the member.B/S multiple structure, requiring relatively independent functional components.Reuse can be relatively good.Would like to buy a table can be reused, rather than doing a table in a stone wall
(5)System Maintenance
C/S program due to the holistic, whole investigation must deal with the problems and system upgrades.Upgrade difficult.Probably do a new system
B/S component composition, replacement of individual aspects of components, to achieve a seamless system upgrade system maintenance overhead is minimized.Users from the Internet to download the installation can be upgraded.(6)Deal with the problem
C/S can handle fixed user plane, and in the same area, security requirements, and operating system-related needs.Should all be the same system.B/S based WAN, for different user groups, geographic dispersion, which is theC/S can not be done.Relationship with minimum operating system platform.(7)User Interface
C/S Multi-Window platform is built on the limited performance of the method, programmers generally higher.B/S based on the browser, there are more rich and vivid expressions and user communication, And most difficult to reduce, reduce development costs.(8)Information flow
C/S program is usually a typical centralized mechanical handling, relatively low interactivity.B/S flow of information can change, change BB BC BG and other information flows, like trading center.Ⅲ AdvantageofB / S
(1)Convenient to update、maintain and develop System.Whenever a server application upgrades, as long as you can upgrade the service application on the server, the browser software on the user's computer without modification, systems development and upgrading maintenance.2、strong open
In the B/S mode, the user access through a common browser, system openness is good.(2)strong open
In the B / S mode, the user access through a common browser, system openness is good.(3)easy to extend
Because the Web is a platform-independent, structural B/S mode can be arbitrarily extended, can contain from one server and several small systems users have thousands of users expanded into large systems
(4)Easy to use
B/S mode applications are based on a Web browser, and a Web browser interface is similar.For non-users switching pages.User contact interface are the same, the user easy to use.阎晓燕

基督山伯爵是法
国作家大仲马的杰出作品。
1815年2月底,法老号远洋货船的年轻代理船长爱德蒙·唐泰斯回到马塞港。老船长勒克莱尔病死在途中,他曾托唐泰斯把船开到一个小岛上去见囚禁中的拿破仑,拿破仑委托唐泰斯捎一封密信给他在巴黎的亲信。唐泰斯这次回国可以说是春风得意:他已经准备好要和相爱多年的女友梅尔塞苔丝结婚,然后一同前往巴黎。但他万万没有想到,在货船上当押运员的唐格拉尔一心要取代唐泰斯的船长地位,唐泰斯的情敌费尔南也对他又嫉又恨。结果两个人勾结到一起,费尔南把唐泰斯的一张告密条送到了当局的手中。正当唐泰斯举行婚礼之际,他被逮捕了。审理这个案子的是代理检察官德·维尔福,他发现密信的收信人就是自己的父亲德·维尔福·诺瓦蒂埃,为了确保自己的前途,他宣判唐泰斯为极度危险的政治犯,并将其打入孤岛上的伊夫堡监狱。[3]、The end of February 815, the young pharaoh the
唐泰斯在死牢里度过了14年的时光,开始的时候他坚信自己的清白,总以为检察官有一天会出现在他面前,宣布他无罪。然而随着时间的推移,他失望了,甚至有过自杀的念头,然而他对未婚妻的思念支撑着他活下去。有一天,他突然听见有人在近旁挖掘的声音,原来是隔壁牢房的法利亚神甫在挖地道,因为神甫的计算错误,地道的出口开在了唐泰斯的牢房。两人相遇后,老神甫帮助他分析了他的遭遇,唐泰斯开始意识到陷害自己的仇人是谁了。在神甫的教授下,唐泰斯还学会了好几种语言,并得知了一个秘密:在一个叫作基督山的小岛上埋藏着一笔巨大的财富。[4]
有一天,法里亚神甫因蜡屈症发作去世了,唐泰斯钻入准备运送神甫死尸的麻袋中,狱卒并没有察觉,将他当作尸体扔进了大海。唐泰斯用小刀划破麻袋,游到了附近的一个小岛上。[1] 次日,一只走私船救了他,他很快和同船员们成了朋友。他利用四处游荡的机会,在基督山岛发现了宝藏:一个大柜分隔成3个部分,分别装着古金币,金块,以及钻石、珍珠和宝石。唐泰斯一下就成了一个亿万富翁,他的目标只有一个,那就是复仇。为此,他要回到社会里去重新获得地位、势力和威望,而在这个世界上只有钱才能使人获得这一切,钱是支配人类最有效和最伟大的力量。此时的唐泰斯已经是一个新人了:有渊博的知识、高雅的仪态和无数的财富,深谋远虑,内心充满了仇恨。[5]
通过多方打探,他核实了唐格拉尔、费尔南和维尔福陷害自己的实情,并得知自己的未婚妻梅尔塞苔丝已经同费尔南结了婚,而自己的老父亲在病中抑郁而死,他的仇恨之火越燃越旺,但他还要为复仇做许多准备工作!8年之后,唐泰斯回到了巴黎。他化名为基督山伯爵,身份是银行家。此时,维尔福是巴黎法院检察官,唐格拉尔成了银行家,费尔南成了莫尔塞夫伯爵,三人都飞黄腾达,地位显赫。[6]
在复仇之前,唐泰斯决定先要报恩。法老号的船主是一个忠厚、勇敢而且热情的人。他曾在唐泰斯落难时为他四处奔波,还帮他照顾年迈的父亲。后来莫雷尔先生破产了,绝望当中,他准备自杀。唐泰斯知道之后,替他还清了债务,送给他女儿一笔优厚的嫁妆,还送给他一艘新的法老号。然后,唐泰斯说:“我已经借天主之手报答了恩人;现在复仇之神授我以他的权力,命我去惩罚仇人!”在报答了曾在他危难之际给过他无私帮助的人之后,唐泰斯开始一步步准备自己的复仇计划了。[7]
基督山伯爵的目标首先是费尔南。费尔南为了谋取一切之私利可以说是坏事做尽,此时他更名换姓,过着养尊处优的生活。基督山伯爵早就摸清了他的底细,伯爵借他人之手在报纸上披露了费尔南20年代在希腊出卖和杀害了阿里总督的事实,引起了议员们的质询。在听证会上,基督山伯爵收养的阿里总督的女儿海黛出席作证,揭发了费尔南在与土耳其人的无耻的交易的中,不但把城堡拱手相让,而且把他的恩主杀害,并把恩主的妻子、女儿作为一部分战利品,卖得40万法郎的罪行。审查委员会断定费尔南犯了判逆罪和暴行迫害罪,这使得费尔南名誉扫地,狼狈不堪。费尔南本来寄希望于儿子阿尔贝,希望他能够同基督山伯爵决斗,以此雪“耻”,但他的妻子(唐泰斯的未婚妻梅尔塞苔丝)早就认出了基督山伯爵就是唐泰斯,她把真相告诉了阿尔贝。最后阿尔贝不顾自己的名声,与基督山伯爵讲和,并决定同母亲一起抛弃沾满了鲜血的家产,不辞而别。无奈之下,费尔南只有自己去找基督山伯爵决斗。决斗时,基督山伯爵用很冷淡的口吻嘲讽地说:“您不就是那个在滑铁卢之战前夕开小差逃走的小兵费尔南吗?您不就是那个在西班牙当法军向导和间谍的费尔南中尉吗?您不就是那个背叛、出卖并谋害自己恩主的费尔南中将吗?而这些个费尔南加起来,不就是现在身为法国贵族议员的您吗?”最后,基督山伯爵说出了自己的真实身份。费尔南失魂落魄地回到家里,正遇上自己的妻子和儿子离家出走,一个去乡下隐居,一个去投军,极度害怕与绝望使得他开枪自杀了。[2]
基督山伯爵的第二个仇人就是唐格拉尔。唐格拉尔在法军入侵西班牙时靠供应军需品发了横财,他的银行可以支配几百万法郎的资产。基督山伯爵为了取得唐格拉尔的信任,拿出欧洲大银行家的三封信。在唐泰斯那里开了三个可以“无限透支”的帐户,慑服了唐格拉尔。之后他又收买了电报局的雇员,发了一份虚报军情的电报,诱使唐格拉尔出售债卷,折损了一笔巨款。基督山伯爵于是将一个逃犯——维尔福和唐格拉尔夫人的私生子安德烈亚·卡瓦尔坎蒂打扮成意大利亲王的儿子,并介绍给唐格拉尔。为了避免银行的倒闭,唐格拉尔将女儿欧仁妮嫁给了“亲王之子”。在婚礼上,宪兵逮捕了这个逃犯,让唐格拉尔出了大丑。在无奈之下,唐格拉尔窃取了济贫机构的500万法郎逃往意大利。途中,他落在了基督山伯爵的强盗朋友路易吉·万帕的手上。他们先把他饿得半死,然后以10万法郎的高价向他出售一顿饭,直到把他的500万法郎全部都榨光。唐格拉尔被迫为自己所犯的罪行忏悔,而此时基督山伯爵出现了,向他公开了身份,说:“我就是那个被你出卖和污蔑的人。我的未婚妻被迫改嫁,我的父亲被你害得饿死。我本来也应该让你死于饥饿,但我饶恕你!”唐格拉尔听后大叫一声,倒在地上缩成一团。随后,基督山伯爵给了他5万法郎让他自谋生路。唐格拉尔饱受折磨和惊吓,他的头发全白了。[8]
基督山伯爵最大的仇人是维尔福,他决定用更残忍的手段摧毁维尔福的一切。他先买下了维尔福以前的一所处所,在这里维尔福曾企图残忍地活埋自己和唐格拉尔夫人的私生子(安德烈亚·卡瓦尔坎蒂)。然后他巧妙地将二人引到这里,并点出了两人当年的丑事。结果,唐格拉尔夫人当场晕倒,维尔福也不得不靠在墙上喘息。经过一番较量之后,维尔福开始对基督山伯爵的身份产生了怀疑。他找到基督山伯爵的两个密友询问,但这两个密友都是基督山伯爵一个人扮演的,他自然一无所获。此时,基督山伯爵注意到了维尔福家庭内部的一个破绽:维尔福的后妻企图让自己的孩子独自继承遗产。于是他假装无意之中透露给了她一个毒药配方,[9] 后妻利用这种毒药毒死了维尔福的前岳母、老仆人,并阴谋毒死前妻的孩子瓦朗蒂娜。由于曾经的因缘关系,基督山伯爵对瓦朗蒂娜暗中保护,并让她暗中观察到了继母下毒的过程。最后,基督山伯爵将这个孩子送到了基督山岛上。维尔福发现自己妻子下毒后对自己妻子一番恶语后审理了险些成了唐格拉尔女婿的逃犯杀人案。在基督山伯爵的授意下,逃犯当众说出了自己的身世。维尔福知道已落到一个复仇之神的手里,被迫承认“无须证据,这个青年人所说的话都是真的……从此刻起,我悉听下任检察官的发落。”这时,维尔福的脸色像死人一样苍白,牙齿像一个发寒热的人那样格格的打抖。回家的路上,他想起了自己恶语相对的妻子渴望与妻子和儿子一块生活。当他仓惶地回到家里,发现自己妻子因为后悔下毒而与儿子一起服毒自杀了。在巨大的打击之下,维尔福疯了。[10]
基督山伯爵大仇已报,他深深地感谢上帝。在他看来,他所做的一切都是秉承上帝的旨意,假基督之手在人间扬善惩恶。他说:“现在我的工作完成了,我的使命也终止了。别了,巴黎!”于是,他同海黛远走高飞了。
