【正文】 基于 Web 的畢業(yè)設計的設計與實現(xiàn) 摘 要 :本系統(tǒng)是針對現(xiàn)代高校計算機技術的發(fā)展，為了應對以往畢業(yè)生畢業(yè)設計中遇到的工作效率低，交互性差等問題而采用軟件工程的設計思想設計的。本文的基礎就是利用 技術與 Web 數(shù)據(jù)庫的結合，開發(fā)出的一個基于 Web 技術的 B/S 結構的畢業(yè)設計管理系統(tǒng)。 首先，本文探討了數(shù)據(jù)庫運行的體系結構，介紹了瀏覽器 /服務器模式的工作方式及特點；比較了主機 /終端、客戶機 /服務器和瀏覽器 /服務器等三種模式各自的優(yōu)缺點。比較結果表明，瀏覽器 /服務器模式繼承了客戶機 /服務器模式的優(yōu)點并克服 了它的缺點，不受操作系統(tǒng)和硬件的制約，而且能防止“胖客戶機”現(xiàn)象的發(fā)生，比較容易實現(xiàn)不同網(wǎng)絡間的連接。瀏覽器 /服務器模式是目前廣泛使用的主體結構。因此，我們開發(fā)的本系統(tǒng) 也將 采用了瀏覽器 /服務器模式。在此基礎上，本文還探討了實現(xiàn) Web 數(shù)據(jù)庫的不同方法。本文重點 還 討論了如何利用 技術和 對象來實現(xiàn)對數(shù)據(jù)庫的訪問方法，給出了設計細節(jié)和具體步驟及其方法。 本次設計是應用 技術實現(xiàn)網(wǎng)絡環(huán)境下的畢業(yè)生畢業(yè)設計管理。利用 Microsoft Visual 工具結合使用 SQL Server 數(shù)據(jù)庫， 、 C、 等技術的工作原理及特點，并以此為理論技術依據(jù)闡述了基于 Web 的畢業(yè)設計管理系統(tǒng)的結構設計和具體的實現(xiàn)過程。 關鍵詞 :B/S 結構， C/S結構， Web 數(shù)據(jù)庫，三層式結構，畢業(yè)設計管理系統(tǒng)， The Design and Realization of Graduation Project Management System Based on Web Abstract :This system is designed in allus ion to the development of modern puter technology in universities and colleges. It adopts the design ideology of software engineering, in order to answer the problems that had been faced by the graduates in their graduation projects, such as low work efficiency, and poor interaction. The foundation of this text was bining the skill of with Web Database, and exploiting a management system based on the skill of Web and the structure of B/S. Firstly, this text discusses the system and structure run by database, introduces the working and characteristic of the B/S pattern, and also pares with three kind of patterns respective advantage and disadvantage among Mainframe/Terminal， Client/Server and Browser/Server. The result indicates that the mode of B/S inherits the merit of C/S, and conquers its shorting. This mode is not conditioned by OS and hardware, and also can prevent the fat client happening, even it can easily connect different works. The mode of B/S is the main structure used widely at present. Therefore this system adopts the mode of browser/server. On this foundation, this text discusses the different ways to actualize Web Database. The discussion centre on how to use the technology and the object of to make the visitorial way to database e true, and shows the details of design and detailed steps. This design applies technology to solve practice of graduation project management in the work environment. Using the tool of Microsoft Visual and bining with SQL Server Database, the working elements of , C, , etc. It takes this for the foundation of academic technique, and expatiates the structural design and the detailed process of carrying out the graduation project management based on Web.
