【正文】 就必須坐在接入網(wǎng)絡的電腦前 ： 而且課程開設(shè)的通知等等也是要通過上網(wǎng)才知道，對于一些不常上網(wǎng)的同學可能就會錯過很多有用的消息，比如說課程調(diào)整通知、考試安排等等。 B/S 模式的選課系統(tǒng)只需要一臺能訪問網(wǎng)絡的瀏覽器即可。同時，為今后開發(fā) 出 適合我校 情況 的移動選課系統(tǒng)打下基礎(chǔ)。服務器端采用 SQL 數(shù)據(jù)庫服務器， Tomcat Web 服務器以及 Java Servlet 的 Web 服務器編程技術(shù)構(gòu)建移動選課的應用服務系統(tǒng)；客戶端采用 Android 平臺的客戶端軟件用來登錄服務器。 基于上述考慮， 客戶端與服務器之間的通信采用 Http 通信協(xié)議。 如今，高校 的網(wǎng)上選課系統(tǒng) 都是比較成熟完善的。因此， 學生需要另一種的選課系統(tǒng)來解決當前選課系統(tǒng)存在的問題，來分流由于傳統(tǒng)網(wǎng)絡訪問給服務器帶來的壓力。在如此龐大的用戶基數(shù)影響下，移動互聯(lián)網(wǎng)技術(shù)得到了飛速的發(fā)展，我國的網(wǎng)民也正在從傳統(tǒng)的互聯(lián)網(wǎng)向移動互聯(lián)網(wǎng)轉(zhuǎn)移。有時為了選擇到自己喜歡的課程，往往要 提前半小時到一個小時在計算機上登錄選課系統(tǒng)，守候在計算機旁邊，而不能做到隨時隨地的選課。這樣，雖然能夠滿足大部分學生的選課需要。 關(guān)鍵詞： 移動選課 ， Android， Java Servlet， C/S 架構(gòu) II Design Of Mobile Elective Course System Based On Android ABSTRACT With the development of the inter and the college education’s revolution, universities’ course electing form has changed to inter course electing form from traditional one which uses paper materials. Nowadays, PDA phone and other mobile instruments have explored a very broad way in this society. Mobil elective course system is one another system which uses the inter to choose course. There are a few of soft wares appearing on the inter about course electing. However, there are little soft wares have the functions about Mobil elective course system. Under this situation, this system wrote this essay mainly talking about how to broadly use the Android system to design and explore Mobil elective course system. This essay as the supplementary ways based on some existing inter course electing systems is mainly to provide convenient and efficient ways for students’ course electing needs. After the basic study about the Android system exploration and the Java Servlet programming technology, this system bined the Mobil inter’s characters to get a summary which is about Mobil elective course system main functions. Through some system exploitation this system made a project about it. This system has some parts such as: system register, course elective information, course electing, course canceling, checking about the chosen courses, etc. During this designing process, this system used C/S and Http. The server uses JDBC date resource to municate. The phone use flow as the way to receive date from Web server.
