1、 Design and Implementation of Educational Video Platform for Multiple Users 多用户教育视频平台设计与实现 院 系 经济与管理学院 专 业 信息管理与信息系统 班 级 94080201 学 号 2009040802005 姓 名 孙文博 指导教师 王庆军 职 称 副教授 负责教师 王晓斌 沈阳航空航天大学 2013 年 6 月 what are C/S with B/S For C/S with the technology of B/S develop change know , first,must make it

2、clear that 3 problems. ( 1 ) What is the structure of C/S. C/S ( Client/Server ) structure, the server structure and client computer that all know well. It is software systematic architecture, through it can hold hardware environment fully using two advantage, realize task reasonable distribution to

3、 Client end and Server end , have reduced systematic communication expense. Now, the most systems of application software are the two levels of structure of the form of Client/Server , are developing to the Web application of distribution type since current software application is systematic, Web an

4、d the application of Client/Server can carry out same business handling , apply different modular to share logic assembly； Therefore it is systematic that built-in and external user can visit new and existing application , through the logic in existing application system, can expand new application

5、system. This is also present application system develop direction. Traditional C S architecture though adopting is open pattern, but this is the openness that system develops a level , in specific application no matter Client end or Server end the software that need to still specify support. Because

6、 of the software software that need to develop different edition according to the different system of operating system that can not offer the structure of C/S and the open environment of user genuine expectation , besides, the renovation of product is very rapid, is nearly impossible to already meet

7、 the 100 computer above users of local area network at the same time use. Price has low efficiency high. If my courtyard uses , Shanghai exceed the orchid companys management software statistics of law case is typical C S architecture management software. ( 2 ) What is the structure of B/S. B/S ( Br

8、owser/Server ) structure browser and server structure. It is along with the technology of Internet spring up , it is for the structure of improvement or a kind of change of the structure of C/S. Under this kind of structure, user working interface is to realize through WWW browser, lose the logic of

9、 general affairs very much in front( Browser) realization, but the major logic of general affairs in server end( Server) realization, form the three-layer claimed 3-tier structure. So, have simplified customer end computer load greatly , have alleviated system to defend workload and the cost with up

10、grading , have reduced the overall cost of user ( TCO ). With present technology see , local area network the network application that establishes the structure of B/S , and under the pattern of Internet/Intranet, database application is easy to hold relatively , cost also is lower. It is that onene

11、ss goes to the development of position , can realize different people, never same place, with difference receive the way of entering ( for example LAN, WAN, Internet/Intranet etc.) visit and operate common database； It can protect data platform efficiently with management visit limits of authority,

12、server database is also safe. Now in my courtyard, net ( Intranet ) , outer net ( Internet ) with Beijing eastern clear big company law case and the management software of official business is the structural management software of B/S , policemen each working station in local area network pass throu

13、gh WWW browser can realize working business. Especially in JAVA step platform language appearance after, the configuration management software of B/S is more facilitated , is shortcut, efficient. ( 3 ) The management software technology of main stream. The technology of main stream of management sof

14、tware technology is as management thought , have also gone through 3 develop period. First, interface technology goes to Windows graph interface ( or graph user interface GUI ) from last century DOS character interface, till Browser browser interface 3 differences develop period. Secondly, today own

15、 the browser interface of computer, is not only visual and is easy to use , what is more major is that any its style of application software based on browser platform is as, make the requirement of choosing a person for the job for operating training not high and software operability is strong , is

16、easy to distinguish； Moreover platform architecture the file that also goes to today from past single user development server ( F S ) system and client computer server ( C S ) system and browser server ( B S ) system. The comparison of C/S and B/S C/S and B/S is the now world two technologies of main stream of developing
