The paper first introduces the development of remote education, the objectoriented development platform JSP and the brief knowledge of UML. Then a detailed introduction is given on the development process of a teaching management system through inter based on JSP with UML as modeling language. Constructing use case model through using use case diagram, sequence diagram and activity diagram to make clear user39。本文對如何運用面向對象的方法來快速高效的開發(fā)一個復用性良好的安全的網(wǎng)絡應用程序提供了一個良好的思路。數(shù)據(jù)庫設計給出數(shù)據(jù)庫模型和數(shù)據(jù)庫中各個表的字段結構。在系統(tǒng)設計過程中，首先設計系統(tǒng)構架，劃分功能模塊，并給出功能設計。構建基于 Java 技術的網(wǎng)絡教學管理系統(tǒng)是進行遠程教學的迫切需要 .本文首先介紹了遠程教育的發(fā)展狀況，面向對象 的系統(tǒng)開發(fā)平臺以及對 Web 應用系統(tǒng)的支持，對象建模語言 UML 的基本知識。論文是本團隊幫同學做過的案例，需 要畢業(yè)論文設計（論文 +源程序 +答辯 PPT）的同學聯(lián)系 799523222 畢業(yè)設計（論文 ） 基于 jsp（ java） 網(wǎng)絡教學平臺系統(tǒng)的設計和開發(fā) 姓 名 系 別、 專 業(yè) 導 師 姓 名、職 稱 完 成 時 間 I 摘 要 遠程教育作為現(xiàn)代教育技術的形式，給教育思想與技術帶來了革命性的變革，己經(jīng)成為現(xiàn)代教育的必然要求。遠程教育要得以順利、高效的實施，必然離不開高效的管理與支撐平臺環(huán)境。然后主要介紹了以 UML 為建模語言，開發(fā)基于 JSP/Servlet 的網(wǎng)絡教學管理系統(tǒng)的過程使用用例圖，順序圖和活動圖來尋找用戶需求，明確用例中對象之間的關系，從而建立系統(tǒng)的用例模型；分析類，確定了系統(tǒng)中的對象抽象成類：這樣完成了系統(tǒng)分析。在功能設計中，構建設計類，運用設計類順序圖，類圖來實現(xiàn)了系統(tǒng)的設計模型。最后一章對系統(tǒng) 關鍵實現(xiàn)做了探討，分別實現(xiàn)了用戶身份鑒別，會話跟蹤，數(shù)據(jù)庫連接池和數(shù)據(jù)優(yōu)化并對系統(tǒng)安全作出說明。 關鍵詞： 遠程教育 ,教學管理 ,UML,網(wǎng)絡教學 II Abstract As a representation of contemporary education, remote education, which has brought the traditional education revolutionary ideas and technologies and optimized the educational resources, has been the trend of the contemporary education. Remote education can39。s requirement and the relation between objects in use case. Through analysing classes to confirm the objects in system and abstract them to classes. So the analysis of system is pleted. Among the design process of system, designing the system architecture, partitioning the system to several subsystem and function models according to use cases and giving the function design of one subsystem. The function design includes the classes design and the following sequence diagram and class diagram. Database design involves a database logic model and the structure of all labels. In the end,I implement some key technologies of system such as user’s identity ,session track, database pool ,data process optimizing and system security. To ensure security, a reliable and practical security policy, in which container based declarative security is dominant and programmatic security is plementary, is given respectively to the web tier, EJI tier and data tier of the system according to the system framework .This article also supplies a good idea on how to develope reusable and safe web application quickly with objectoriented methodology.
