【正文】 操作，其他的類直接或間接繼承基本類。實現(xiàn)功能模塊時，因為要實現(xiàn)教師立題、學(xué)生選題以及選題管理模塊，故應(yīng)先將職稱、學(xué)位、專業(yè)信息、教研室、辦學(xué)層次、課題類型、課題來源這些獨立模塊分別實現(xiàn)，其次實現(xiàn)獨立模塊分別實現(xiàn)，在實現(xiàn)學(xué)生、教師模塊，最后實現(xiàn)立題、課題管理模塊。核心功能主要為教師立題、學(xué)生選題、課題管理。從管理的角度可以將畢業(yè)設(shè)計管理系統(tǒng)分為八個部分：課題信息管理、職稱學(xué)位管理、專業(yè)信息管理、用戶信息管理、立題信息管理、選題信息管理、其他信息管理和統(tǒng)計信息管理。其次，通過本課題可以使自己更進一步的了解軟件開發(fā)流程，同時對 J2EE 平臺與 MS SQL SERVER 有進一步的了解，使用更加熟練。 畢業(yè)設(shè)計系統(tǒng)的現(xiàn)狀 本課題開發(fā)的目的在于解決以往畢業(yè)設(shè)計管理過程中存在的問題，解決效率低、容易出錯等問題，從而對畢業(yè)設(shè)計信息進行更好的管理，對畢業(yè)設(shè)計的數(shù)據(jù)進行統(tǒng)計分析。通過這套畢業(yè)設(shè)計管理軟件可以解決畢業(yè)設(shè)計過程管理工作中存在的工作效率低，交互性差等問題，對高校管理學(xué)生畢業(yè)設(shè)計意義重大。使用 Excel 軟件分析統(tǒng)計畢業(yè)設(shè)計制作情況，該軟件存在許多不足，如：立題不靈活，選題必須集中，對于整個院系選題有諸多不便；畢業(yè)設(shè)計評分也必須集中錄入等；統(tǒng)計畢業(yè)設(shè)計制作情況也不能自動完成。Graduation design management。s a system that to manage the graduation system implement the function of adding subject,selecting the subject,and managing the subject.
