畢業設計-jsp在線選課系統設計與實現(已修改)

　

【正文】 在線選課系統的設計與實現 摘 要 由于學校教學制度的改革，現在大部分高等院校開始實行的是學生的自主選課模式，傳統的教學模式（學生按照學校安排好的課程上課）已經不能適應新型的教學手段，如果仍然通過紙上的方式選課，一方面浪費的大量的人力、物力資源，另一方面浪費時間以及在人為的統計過程中不可避免出現的差錯等情況。隨著高校人數的增多，這種弊端會越來越多的暴露出來。在線選課系統的實現顯得尤為必要。 針對學生選課這一環節，本系統從學生網上自主選課以及教師的課程發布和管理員信息管理三個大方面進行了設計，基本實現了學生的在 線信息查詢、選課功能以及教師對課程信息發布的管理 和管理員對學生和教師信息的管理等功能。 關鍵詞 ： 在線選課 ； B/S 結構 ； JSP； J2EE； MySQL； Online Course Selection System Design and Implementation Abstract As the reform of school education, most colleges and universities are now beginning to implement the student39。s own course selection patterns, the traditional teaching model (the students arranged in accordance with school curriculum classes) can not adapt to new teaching methods, if they remain on paper on the way to course selection, on the one hand and waste a lot of manpower, material resources, on the other hand a waste of time and in the process of artificial statistical errors inevitably occur and so on. With the increasing number of universities, such shortings would be exposed more and more. Online Course Selection System is particularly essential. Elective for students in this part of the system independently from the online course selection students and teachers and administrators released information management courses are three major aspects of the design, the basic realization of the students online information inquiry, course selection function as well as teachers of the curriculum information dissemination management and administrators to students and teachers to information management. Key Words: Online course selection。 B / S structure。 JSP。 J2EE。 MySQL。 目 錄 摘 要 ..............................................................................................................................
