【正文】 青島理工大學(xué)畢業(yè)論文（設(shè)計(jì)） I 摘 要 隨著在校大學(xué)生人數(shù)的不斷增加，教務(wù)系統(tǒng)的數(shù)據(jù)量也不斷的上漲。以往的選課方法是隨堂報(bào)名。這種方法雖然直接，但是造成選課的盲目性和教務(wù)處處理數(shù)據(jù)的繁重性。為了減輕教務(wù)處工作，以及每個(gè)學(xué)生更好的選擇自己所喜歡的科目。針對(duì)學(xué)生選課這一環(huán)節(jié)，本系統(tǒng)從學(xué)生模塊、教師模塊以及管理員模塊三個(gè)大方面進(jìn)行了設(shè)計(jì)，基本實(shí)現(xiàn)了學(xué)生的在線信息查詢、選課功能以及管理員對(duì)系統(tǒng)的整體管理和課程信息發(fā)布的管理等功能。 本文通過分析瀏覽器 /服務(wù)器 架 構(gòu) 的特點(diǎn)并結(jié)合選課的實(shí)際情況，提出了基于瀏覽器 /服務(wù)器 架 構(gòu) 網(wǎng)上選課系統(tǒng) 的基本設(shè)計(jì)思想，簡(jiǎn)要介紹了系統(tǒng)各功能模塊，著重討論了 數(shù)據(jù)庫的設(shè)計(jì) 及 用 SQL Server 2021開發(fā)網(wǎng)上選課系統(tǒng)時(shí)的數(shù)據(jù)庫訪問技術(shù)和動(dòng)態(tài)網(wǎng)頁制作技術(shù) ,并給出了部分實(shí)現(xiàn)代碼。通過該系統(tǒng)，使學(xué)生可以方便地在校園網(wǎng)上進(jìn)行網(wǎng)上選課。該 B/S架 構(gòu)的系統(tǒng)在 Windows XP/Windows 7系統(tǒng)和 下 開發(fā)完成 ，使用 C＃作為 ，SQL Server 2021作為數(shù)據(jù)庫。系統(tǒng)有較高的安全性和較好的性能。其中連接數(shù)據(jù)庫的字符串在 置 ， 增加了靈活性， 并經(jīng)過編碼加密，提高 了數(shù)據(jù)庫的安全 性 。代碼盡量使用存儲(chǔ)過程和盡量減少數(shù)據(jù)庫連接的打開時(shí)間等手段來提高性能。 網(wǎng)上選課在全球高校已趨向普遍，網(wǎng)上選課系統(tǒng)也會(huì)在不斷的實(shí)際應(yīng)用中得到更多機(jī)會(huì)的發(fā)展和完善。相信系統(tǒng)以后會(huì)向著更加完善、更加 高 效、更加簡(jiǎn)潔和更加人性化的方向發(fā)展。 關(guān)鍵詞 ： 網(wǎng)上選課，瀏覽器 /服務(wù)器， ,數(shù)據(jù)庫管理系統(tǒng)青島理工大學(xué)畢業(yè)論文（設(shè)計(jì)） II ABSTRACT With the increase of the enrolling number, the data for daily registry is increasing, too. As usual we should go to classroom to enroll. Although the method is simple, but result in blindness of the course enrollment and the heavy of registry data processing. In order to reduce the work of registry ,and for each student to choose their own favorite subjects better. The system included three modules : student module, teacher module as well as system manager module. It realized student39。s online information inquiry, choose class function as well as system39。s whole management and curriculum information issue functions and so on. This paper showed the basic design ideas of the Browser/Server architecture based on online course selection system by analyzing the characteristic of the Browser/Server architecture and bining with the actual public elective courses conditions of our school． It introduced the function module and database design briefly， followed by a discussion on database accessing technology and the active page technology of the course select system based on and SQL Server 2021． By using this system， students could select courses online efficiently． This Browser/Server architecture system was developed in platform in Windows XP ?operating system, using C as development language and SQL Server 2021 as the database. This system had higher security and better performance. The parameter, which is used to connecting with the database, could be modified at any time in the file “ ”. The string was encoded and encrypted, increasing flexibility of the system and security of the database. In code implementation, stored procedure was used to minimizing the database opening time and improving performance of the system. Online class selection bees more and more popular now, It will also obtain 青島理工大學(xué)畢業(yè)論文（設(shè)計(jì)） III more development and improvement opportunity in the unceasing practical application. Wish the system will be more perfect, efficiency, and have a good development.
