【導(dǎo)讀】腦公司的銷售和庫存管理問題。開發(fā)該系統(tǒng)包括數(shù)據(jù)庫的建立與維護(hù)以及應(yīng)用。本系統(tǒng)的設(shè)計題目來自于鎮(zhèn)江國恩電腦公司。脫離手工的操作，讓公司各部門能夠更高效的運轉(zhuǎn)，資源能夠更為合理的利用。在公司編程人員及。指導(dǎo)老師的幫助下，我選擇了原型法，利用Powerbuilder作為開發(fā)工具，在WindowsServer2021+SQLServer2021平臺上來開發(fā)該信息系統(tǒng)。的模型，形成了完整的計算機(jī)銷售管理系統(tǒng)。

　　

【正文】 的權(quán)限設(shè)置是如何進(jìn)行的呢？首先，在權(quán)限設(shè)置前，你必須要選擇要對此進(jìn)行設(shè)置權(quán)限的用戶，雙擊用戶的頭像，然后，再對應(yīng)項的功能付權(quán)限（給予權(quán)限的在前面打上勾），檢查無誤后，按“確定”按鈕，提交你授權(quán)結(jié)果。 雖然，通過前面的設(shè)置可以避免很多數(shù)據(jù)的不安全性，但是，那只是停留在，對沒有登陸身份用戶而言的，或者是由于超級用戶和系統(tǒng)維護(hù)員的失誤造成的，為了解決，對有登陸身份的用戶 和超級用戶和系統(tǒng)維護(hù)員的失誤造成的不安全性，我特意添加了“系統(tǒng)日志”功能，在此將會記錄下某個登陸人員在系統(tǒng)中的詳細(xì)操作過程和操作的時間以及操作的模塊。在系統(tǒng)日志中，具有如下的功能：單條記錄的刪除，整個記錄的清空操作，簡單的統(tǒng)計出某個用戶的所有上機(jī)記錄，以及查詢出符合條件的記錄和打印功能。 系統(tǒng)幫助的實現(xiàn) 對一個系統(tǒng)而言，強(qiáng)大的幫助功能是必須的。這不僅為操作員帶來了操作上的指南，而且，也是一個系統(tǒng)必不可少的組成部分。 我所設(shè)計系統(tǒng)幫助完全是模擬 Power Builder 自帶的幫助設(shè)計的。它主 要的組成部分有兩個，一個提供了瀏覽查詢功能，另一個模糊查詢功能。如果用戶對系統(tǒng)的幫助內(nèi)容十分的熟悉，他可以使用瀏覽查詢功能，因為我設(shè)計的該功能是按照分類存放的，知道大類，便可以找到響應(yīng)的具體小項；如果用戶對系統(tǒng)的幫助不熟悉，則可以輸入自己想要查詢的內(nèi)容的關(guān)鍵字搜索，如果系統(tǒng)提供你想要的幫助，將會把焦點從第一行轉(zhuǎn)移到對應(yīng)的項目上去。 除了有系統(tǒng)的幫助外，我在此還提供了軟件注冊，關(guān)于軟件和版本信息，在軟件注冊里，主要是對本軟件注冊，只有注冊了本軟件才不會受到本軟件的試用期的限制，這是為了保護(hù)知識產(chǎn)權(quán)而設(shè)置的。關(guān) 于軟件和版本信息主要提供的本軟件的作者信息和本軟件的使用次數(shù)等信息。 本系統(tǒng)的幫助界面如下所示： 第五章 系統(tǒng)的實現(xiàn) 34 參考文獻(xiàn) 35 參 考 文 獻(xiàn) [1] 《 Powerbuilder 高級編程技術(shù)》，出版社 : 北京希望電子出版社作者 : 陳明 , 楊勁松， 2021 [2] 《 Powerbuilder 教程》，出版社 : 北京希望電子出版社， 作者 : 郭興成，2021 [3] 《 Powerbuilder 時尚編程百例》，出版社 : 機(jī)械工業(yè)出版社 ，作者 : 網(wǎng)冠科技， 2021 [4] 《 Powerbuilder 實例教程》，出版社 : 北京希望電子出版社 ，作者 : 張長富， 2021 [5] 《 Powerbuilder 實用教程》，出版社 : 電子工業(yè)出版社， 作者 : 鄭阿奇 ,殷紅先 ,張為民， 2021 [6] 《數(shù)據(jù)庫原理與技術(shù)》，出版社 :科學(xué)出版社， 作者 :金銀秋 ,肖慎勇 ,黃杰， 2021 [7] 《信息系統(tǒng)開發(fā)方法教程》，出版社 :清華大學(xué)出版社， 作者 :陳佳， 2021 [8] 《計算機(jī)世界周報訂閱》，出版社和作者不詳 ,來自于 Powerbuilder 論壇， 2021 [9] 《計算機(jī)世界日報》，出版社和作者不詳 ,來自于 Powerbuilder 論壇， 2021 [10] 《計算機(jī)世界編程技巧》，出版社和作者不 詳 ,來自于 Powerbuilder 論壇， 2021 [11] 《 SQL Server 2021 簡明教程》，出版社 :清華大學(xué)出版社 ，作者 :黃維通， 2021 [12]《 SQL Server 2021 中文版》，出版社：清華大學(xué)出版社，作者：周緒， 2021 [13]《管理信息系統(tǒng)的分析與設(shè)計》，出版社：天津科技翻譯出版中心，作者：王守茂， 1996 [14]《軟件工程導(dǎo)論》，出版社：清華大學(xué)出版社，作者：張海藩， 1990參考文獻(xiàn) 36 致 謝 本設(shè)計說明書詳細(xì)的介紹了《計算機(jī)銷售管理系統(tǒng)》的設(shè)計過程，和設(shè)計的思想，在論述系統(tǒng)的各 模塊的過程中，由于時間和篇幅的限制，不能逐一的對個模塊剖析解說，凡事有主次之分，我把各模塊中我覺得有代表意義和新穎的窗口作為了重點和代表，希望各位老師和同學(xué)諒解。 在幾個月的努力下，我的畢業(yè)設(shè)計終于告以段落，在此，我忠心的向我的畢業(yè)設(shè)計老師管寶云老師，并向那些關(guān)心我和在設(shè)計過程中幫助和鼓勵我的領(lǐng)導(dǎo)、老師、同學(xué)致意良好的祝愿！ 最后，感謝所有關(guān)心和支持我的同學(xué)們和老師們！ 參考文獻(xiàn) 37 ulped a swig of jumpjuice from a cracked glass, focused blearily on the screen. The young king was answering a question about the late Warlord Derek Sagan. He was not perfect. No man is perfect, His Majesty was saying gravely. He made mistakes. I beg your pardon, Your Majesty, James M. Warden respectfully contradicted, but some might consider the word mistakes inappropriate for what many consider to be heinous crimes. Try murder! Bosk yelled loudly at the screen. His Majesty was shaking his head, almost as if he39。d heard Bosk39。s ment. Lord Sagan was a warrior. He acted out of his own warrior code, which, as you kno w, is a harsh one. But he held to that code with honor. He took part in the revolution because he believed that the government unde r my late uncle39。s rule was corrupt and ineffective. That it was about to collapse into anarchy, which would have put all the people in the galaxy in the gravest danger. When L ord Sagan discovered tha t the new government under President Peter Robes wa s every bit as corrupt as the old, the Warlord concluded that heone of the few surviving members of the Blood Royal had the right to try to seize control. Circumstances, the Creator, Fate call it what you willintervened. Lord Sagan39。s ambitious and, some might say, his despotic plans failed. King Starfire39。s hand clenched. The famous Starfire blue eyes were lit from within by a radiance that looked well on the vidsc reens. The redgolden lion39。s mane of hair framed a face that was youthful, handsome, earnest, intense. His godlike looks, his vibrant personality all were rapidly making a reluctant deity of a very mortal young man. But I tell you, Mr. Warden, and I tell my people that I would not be here now, I would not be wearing this crown, the galaxy would not be at peace today, if it were not for the sacrifices of Lord Derek Sagan. He attempted to correct the great wrongs he had done and, in so doing, gave his life that others might live. He is one of the greatest men I have ever known. I will always honor his memory. Bosk tossed the remainder of the jumpjuice at the vidscreen. Here39。s that for his fuc kin39。 memory. The juice tric kled down the screen, soa ked into the threadbare carpet which covered the floor of the shabby studio apartment. A crisp knock sounded on the door. Lurching to his feet, Bosk went to answer it. On his way, he made a detour to the bottle, poured himself another drink. Reach ing the door, he peeped out the oneway peephole, saw a man dressed in a suit, carry ing a briefcase. The man didn39。t look threatening. He didn39。t look anything. He had one of those faces you meet and five minute s later you can39。t recall ever having been introduced to him before. Bosk was more interested in the briefcase. It is said that Adonians can smell money. Bosk39。s nose twitched. He opened the door. Yeah? he said, looking first at the briefcase, then finally lifting his gaze to meet the stranger39。s. What39。s the deal? I don39。t be lieve it would be wise for us to conduct our business in the hallway, the stranger said. He wasn39。t even breathing hard after the long climb. He smiled in a pleasant and disarming manner. Your neighbors don39。t need to know your affairs, do they? Bosk followed the stranger39。s glance, saw Mrs. Kasper standing in her halfopen door. He glared at her. I heard a knock, she said defensively. Thought it might be for me. She sniffed. Another of your 39。clients39。? Nosy old bitch! Bosk retorted. He opened his own door wider. C39。mon in, then. 參考文獻(xiàn) 38 The stranger entered. Bosk shut the door, took a look out the peephole to ma ke sure Mrs. Kasper had gone back into her apartm ent. She had a bad habit of loitering in the hall, listening outside closed doors. Sure enough. Bosk flung the door open, nearl
