【正文】 24 結束語 二十一世紀是一個高速、快捷的年代。因此，辦公自動化的高速度、高效率、高便捷、低成本便成了我們的目的，為此開發(fā)了這個火車站網(wǎng)上訂票系統(tǒng)。 這次系統(tǒng)的設計從最開始的可行性研究，需求分析，到系統(tǒng)的總體設計，詳細設 計，再到編碼、測試等的一個整體過程，使我真正明白了要做一個軟件的難度，特別是要做一個真正可用的軟件，就更難了。當然，我的個人能力有限，還有很多不足的地方，敬請諒解。其中，最關鍵的是在最初對系統(tǒng)的需求分析做的不透徹，導致后續(xù)設 計工作乃至編碼時的修改工作量變大。所以，通過這次課程設計我深刻體會到軟件工程還是必須學精通點、學透徹點?？傮w來說，課程設計讓我學了不少知識。 25 致謝 在論文完成之際，我要特別感謝我的 指導老師趙運紅老師的熱情關懷和悉心指導。 在論文的寫作過程中，也得到了許多同學的寶貴建議，同時還得到許多在工作過程中許多同事的支持和幫助，在此一并致以誠摯的謝意。 最后，向在百忙中抽出時間對本文進行評審并提出寶貴意見的各位老師表示衷心地感謝！ 26 參考文獻 [1] 史嘉權 .《數(shù)據(jù)庫系統(tǒng)概論》 .清華大學出版社出版 . 2021 年 1月第 1版 .P151~P174 [2] 張海藩 .《軟件工程導論》 .清華大學出版社出版 .2021年 2月第 5版 .P55~P64 [3] 張榮梅 梁曉林 趙寶琴 . 《 Visual C++實用教程》 .中國鐵道出版社 .2021年 9月第 1版 .P232~P247 P305~P333 [4] 孫涌 .《現(xiàn)代軟件工程》 .北京希望電子出版社 .2021年 8月 .P246 [5] 薩師煊，王珊 .《數(shù)據(jù)庫系統(tǒng)概論》 .高等教育出版社 .2021年 2月 .P460 [6] 湯庸 .《軟件工程方法與管理》 .冶金工業(yè)出版社 .2021年 10月 [7] 張虹 .《軟件工程與軟件開發(fā)工具》 .清華大學出版社 .2021年 9月 [8] 李素若 任正云等 .《 C++面向對象程序設計》 .北京工業(yè)出版社 .2021年 7月 .P272~P289 [9] Stanley 等著 李師賢等譯 .《 C++ Primer 中文版》 .人民郵電出版社 .2021年 6月第 1版 [10] 張淑平 .《程序員教程》（第三版） .清華大學出版社 .2021年 8月 .P382~P430 [11] Rapheal Pender,蘇劍等 .《標準 C++編程寶典》 . 電子工業(yè)出版社 . 2021 年 1月 Visafree policy brings Chengdu biz, tourism boost.
