【正文】 了對(duì)管理信息系統(tǒng)的認(rèn)識(shí)，又進(jìn)一步鞏固了以前所學(xué)的計(jì)算機(jī)軟件開(kāi)發(fā)方面的知識(shí)，提高了軟件開(kāi)發(fā)的水平，從而為今后在實(shí)際工作中更好的應(yīng)用計(jì)算機(jī)進(jìn)行信息管理打下了堅(jiān)實(shí)的基礎(chǔ)。成功 MIS的基礎(chǔ)是科學(xué)的管理加上科學(xué)的開(kāi)發(fā)方式。由于以前根本未曾接觸過(guò)軟件的整體開(kāi)發(fā)設(shè)計(jì)，所以在前期的調(diào)研中相當(dāng)不充分，開(kāi)題開(kāi)題也有些盲目，以為把屬性和表寫(xiě)得越多越好，這個(gè)問(wèn)題越到后來(lái)越嚴(yán)種，而且因?yàn)榭陀^的原因耽誤了進(jìn)度，因而對(duì)開(kāi)題的開(kāi)題做了修改。本文的研究一直是在關(guān)心和幫助下完成的，給了我莫大的幫助。 參考文獻(xiàn) , 《 Database system implementation》 ,機(jī)械工業(yè)出版社 , 2021 GarcialMolina , Jeffrey , Jennifer Widom,《 An introduction to Database Systems(Seventh Edition), 機(jī)械工業(yè)出版社 ,2021 , 郭安源 , 葛曉東 , 《教育信息化系統(tǒng)開(kāi)發(fā)實(shí)例導(dǎo)航》 , 人民郵電出版社 ,2021 ,《數(shù)據(jù)庫(kù)開(kāi)發(fā)技術(shù)與工程實(shí)踐》 ,人民郵電出版社 ,2021 , 王虹 等 《 Visual basic 中文版高級(jí)應(yīng)用與開(kāi)發(fā)指南》 , 人民郵電出版社 , 2021 主編 等 《 VB 課程設(shè)計(jì)與系統(tǒng)開(kāi)發(fā)案例》清華大學(xué)出版社 , 2021 ，《 Visual Basic 數(shù)據(jù)庫(kù)開(kāi)發(fā)及工程實(shí)例》，人民郵電出版社 ，《 Visual Basic 數(shù)據(jù)庫(kù)開(kāi)發(fā)技術(shù)與工程實(shí)踐》，人民郵電出版社， 2021 ，汪遠(yuǎn)征，《 Visual Basic 程序設(shè)計(jì)教程》，機(jī)械工業(yè)出版社， 2021 ，周學(xué)明，郭安源，《 Visual Basic 企業(yè)辦公系統(tǒng)開(kāi)發(fā)實(shí)例導(dǎo)航》，人民郵電出版社，2021 ，王珊，《數(shù)據(jù)庫(kù)系統(tǒng)導(dǎo)論》，機(jī)械工業(yè)出版社， 2021 Are you hungry now? No, I am tired and lazy now。t run, N icholas, Dr. Island said with the voice of a wave. It only makes him angry that you run. N icholas did not answer, but cut to his left, up the beach and among the trunks of the palms, sprinting all the way because he had no way of knowing Ignacio was not right behind him, about to grab him by the neck. When he stopped it was in the thick jungle, among the boles of the hardwoods, where he leaned,.。 there was none. He drew a deep breath then and said, Well, that39。 he was not as strong as he had been only a day past, and by this time next day he would probably be unable to outrun Ignacio. He should, he now realized, have eaten the monkey he had killed。s head。t mistaken after all, was I? I didn39。s a bit frightened of us. Have you ever talked to him, Nicholas? Today I did a little. He told me a story about a pet fish he used to have. Ignacio grew up all alone。t anyone,` just the machines. Now he doesn39。t other people around all the time . Remember that? a Only there. are other people around all the time。t he stay there? Did I tell you about the bird, Nicholas? She had been not listening again. What bird? I have a bird. Inside. She patted the flat stomach below her small breasts, and for a moment, Nicholas thought she had really found food. She sits in here. She has tangled a nest in my entrails, where she sits and tears at my breath with her beak. I look healthy to you, don39。ve swallowed so much I couldn39。m not really me, I39。ll bring you back som e. When he reached the beach, Nicholas turned and walked slowly bac k in the direction of the dead fire, this time along the rim of dampened sand between the sea and the palms. He was thinking about machines. There were hundreds of thousands, perhaps millions, of machines out beyond the belt, but few or none of the sophisticated servant robots of Earththose were luxuries. Would Ignacio, in Brazil (whatever that was like), have had such luxuries? N icholas thought not。 pulsive sweeping and scrubbing palliate its anxieties. It is a strength of Freud39。s。t know. Two, three days ago. Ignacio gave me something. I39。t even wet, and do you know something, N icholas? I39。m hollow and rotten and tur ning brown, dirt and old feathers, oozing away. Her beak will break through soon. Okay. Nicholas turned to go. I39。s how the world is. Not in Brazil, maybe, Nicholas said. He was trying to remember something about Brazil, but the only thing he could think of was a parro t singing in a straw hat from the view cartoons。t want anyone around him. Nicholas said slowly, Dr. Island said lots of people wouldn39。s emptie than it used to be. Where Ignacio was, there would have been Red Indian hunters two or three hundred years ago。s Nicholas, and I called you. Then I thought I might be wrong, or that it might be Ignacio. Ignacio was chasing me. Maybe he still is, but h think he39。 had Dr. Island used that sound to speak to him? He walked toward it and found a little rill that threaded a way among the trees, and followed it. In a hundred steps it grew broader, slowed, and ended in a long blind pool under a dome of leaves. . Diane was sitting on moss on the side opposite him。 he remembered his effort to open a coconuthe had failed, but it was surely not impossible. His mind was hazy as to what a coconut might contain, but there had to be an edible core, because they were eaten in books. He decided to make a wide sweep through the jungle that would bring him back to the beach well away from Ignacio。 there was only the green hush. The light was still bright and strong and nearly, shadowless, but some interior sense told him the day, was nearly over, and he noticed that such faint shades as he could see stretched long, hor izontal distortions of their objects. He felt no hunger, but he had fasted be39。 . sound in an atmosphere silent and unwa ked as Earth39。 words, realizing that they were a signal, he turned and began to run, splashing through the shallow water. Ignacio ran after him, much helped by his longer legs, his hair flying beh ind his dark young face, his square teetheach white as a bone and as big as Nicholas39。再則 ,感謝我的室友 ,由于整個(gè)設(shè)計(jì)都是在寢室的電腦前完成的 ,有時(shí)會(huì)影響你們休息 ,你們卻能夠理解 ,毫無(wú)怨言。 最后就是從一而終的問(wèn)題了，在開(kāi)發(fā)過(guò)程中我遇到了許許多多的問(wèn)題，很多地方都不明白，經(jīng)常有打退堂鼓的想法，我經(jīng)常的請(qǐng)教同學(xué)和老師，最后的成果雖然不很完美，但我盡力了，并有所收獲。 總的來(lái)說(shuō)，在這次的畢業(yè)設(shè)計(jì)種遇到了不少的問(wèn)題，大部分得到了很好的解決，但也有少部分遺留的問(wèn)題。這些都有待進(jìn)一步改善。 系統(tǒng)維護(hù)的組織與管理 系統(tǒng)維護(hù)工作，首先必須建立一個(gè)維護(hù)組織，確定進(jìn)行維護(hù)工作所應(yīng)遵循的原則和規(guī)范化的過(guò)程，此外還應(yīng)建立一套適用于具體系統(tǒng)維護(hù)過(guò)程的文檔及管理措施，以及進(jìn)行復(fù)審的標(biāo)準(zhǔn)。 系統(tǒng)維護(hù)的內(nèi)容 按照維護(hù)對(duì)象的不同，系統(tǒng)維護(hù)的內(nèi)容可分為以下幾類： （ 1）系統(tǒng)應(yīng)用程序維護(hù) （ 2）數(shù)據(jù)維護(hù) （ 3）代碼維護(hù) (4）硬件設(shè)備維護(hù) 系統(tǒng)維護(hù)的類型 系統(tǒng)維護(hù)的重點(diǎn)是系統(tǒng)應(yīng)用軟件的維護(hù)工作，按照軟件維護(hù)的不同性質(zhì)，可以劃 分為下面四種類型： （ 1）糾錯(cuò)性維護(hù) 診斷和修正系統(tǒng)中遺留的錯(cuò)誤。 本系統(tǒng)運(yùn)行：首先啟動(dòng) Windows2021/XP，將本系統(tǒng)拷貝到硬盤(pán)相應(yīng)地目錄下，運(yùn)行“ EXE文件”即可。 系統(tǒng)的配置 硬件配置要求： CPU： PII
