【導(dǎo)讀】在技術(shù)上已逐步成熟。管理信息系統(tǒng)是一個不斷發(fā)展的新型學科,企業(yè)要生。存要發(fā)展,要高效率地把企業(yè)活動有機地組織起來,就必須加強企業(yè)管理,點相適應(yīng)的管理信息系統(tǒng)。上地應(yīng)用開發(fā)”的策略開發(fā)一個管理信息系統(tǒng)的過程。通過分析傳統(tǒng)的人工。管理圖書館的不足,創(chuàng)建了一套行之有效的計算機管理圖書館的方案。列出了幾個主要的程序框圖,并附帶了一些主要的窗口和程序。本系統(tǒng)界面友好,操作簡單,比較實用。

  

【正文】 _count_loan 說明:由于這兩個窗口大同小異,所以僅對 w_count_booktype 進行說明 。 圖 功 能介紹:統(tǒng)計現(xiàn)有各類圖書比例,并以餅型圖顯示出來。 數(shù)據(jù)窗口的數(shù)據(jù)源 SQL 語句: SELECT bookinfo.bookonloan, count(*) FROM bookinfo GROUP BY bookinfo.bookonloan ( 12) 用戶管理窗口 w_people 36 圖 功能介紹:添加、刪除、修改用戶信息。 操作方法: :點擊“添加”按鈕,輸入用戶名、密碼、選擇等級,點擊“保存” :點擊欲刪除的用戶,點擊“刪除”按鈕 :修改用戶信息,點擊“保存”按紐 代碼分析: Open事件:類同“新書入庫窗口 w_newbook” 數(shù)據(jù)窗口 rowfocuschanged事件 :(0,false) //高亮顯示當前選中的行 (currentrow,true) 數(shù)據(jù)窗口 clicked事件: =true //點擊數(shù)據(jù)窗口后使“刪除”按鈕可用 “增加”按紐:類同“新書入庫窗口 w_newbook” “保存”按紐:類同“新書入庫窗口 w_newbook” “刪除”按紐:類同“舊書銷毀窗口 w_delbook” ( 13 )圖書信息設(shè)置 圖書分類設(shè)置窗口 w_bookclass、出版社信息窗口 w_pubinfo 圖 功 能介紹:設(shè)置圖 書分類信息與出版社信息,同時可以對出版社信息進行查詢 37 說明:設(shè)置“圖書分類信息”是為了今后統(tǒng)計現(xiàn)有圖書類型比例,設(shè)置“出版社信息”是為了今后查詢出版社信息 ,同時在“新書入庫”時方便相應(yīng)項目的輸入(下拉 Datawindow) 代碼分析:略 ( 14 )借閱規(guī)則設(shè)置窗口 w_regular 圖 功能介紹:設(shè)置罰金規(guī)則 操作方法:填寫“免費使用天數(shù)”、“罰金費率”,點擊“啟用規(guī)則”開啟或關(guān)閉此項規(guī)則,點擊“確定”實施規(guī)則 。 代碼分析: Open 事件: int li_days dec ld_fine char lc_flag //查詢“免費天數(shù)”、“罰金”、“啟用開關(guān)” 38 select Days,fine,flag into :li_days,:ld_fine,:lc_flag from regular。 =string(li_days) =string(ld_fine) //判斷是否啟用設(shè)置,并表現(xiàn)出來 if lc_flag=39。y39。 then =true =true =true end if =1787 =1120 “啟用”復(fù)選框: if then =true =true else =false =false end if “確認”按紐: char lc_flag int li_days dec ld_fine li_days=integer() ld_fine=dec() //判斷是否啟用規(guī)則 if then if = or isnull() then messagebox(系統(tǒng)提示 ,請輸入免費借閱天數(shù)! ) 39 () return end if if =.00 or isnull() then messagebox(系統(tǒng)提示 ,請輸入罰金! ) () return end if //啟用規(guī)則 lc_flag=39。y39。 else //關(guān)閉規(guī)則 lc_flag=39。n39。 end if //更新規(guī)則 UPDATE regular SET Days=:li_days,fine=:ld_fine,Flag=:lc_flag。 close(parent) “取消”按紐: close(parent) 7 補充說明 ( 1)窗口中的 Tab 順序應(yīng)符合實際操作習慣,并將合適的按鈕設(shè)為 default ( 2)將“刪除”按鈕初始狀態(tài)設(shè)為“非使能”,并在適當?shù)臅r候通過程序使其“使能”,是為了防止誤刪。 ( 3)圖書借閱與歸還窗口中部分輸入框設(shè)為 DisplayOnly,僅做結(jié)果顯示之用?!皻w還” 窗口中“應(yīng)付罰金”輸入框的使能與否由該項規(guī)則是否“啟用”來定。 40 七 結(jié)束語 在對 管理信息系統(tǒng)的開發(fā)過程有了基本了解后,本人使用 PowerBuilder 開發(fā)了這個 “圖書管理系統(tǒng)”。系統(tǒng)基本 實現(xiàn)了內(nèi)部圖書借閱管理的系統(tǒng)化、規(guī)范化和自動化。例如對 圖書進行登記,對舊書進行銷毀。添加借閱人以及注銷借閱人。圖書的借閱、歸還。可以按作者、出版社、出版時間等信息對圖書進行查詢, 并能反映出圖書的借閱情況 。實現(xiàn)了簡單的統(tǒng)計分析功能,可以展示出庫存圖書與借出圖書的比例、館藏圖書種類的情況。并能對借閱規(guī)則進行設(shè)置。還 能夠?qū)κ褂迷摴芾硐到y(tǒng)的用戶進行管理,按照不同的工作職能提供不同的功能授權(quán)。 通過對該系統(tǒng)的設(shè)計、開發(fā)和調(diào)試 , 一方面讓我了解了 MIS系統(tǒng)的開發(fā)過程與方法, 另一方面,讓我 初步掌握 了 PowerBuilder 開發(fā)工具的使用方法,熟悉了窗口、菜單以及一些可視化控件的使用方法。通過使用還了解到窗口對象、數(shù)據(jù)窗口對象、各類控件的屬性與方法。同時,在制作過程中遇到了不少問題和困難,通過查閱書籍及互連網(wǎng)得到了不小的幫助。 因為條件的限制,該管理系統(tǒng)還存在不少的缺點和漏洞,只能盡量改正與完善。不足之處,還請多多指教。 參 考 文 獻 [1].羅超理,李萬紅.管理信息系統(tǒng)原理與應(yīng)用.清華大學出版社, 2021 [2]. 艾德才 . 計算機信息管理基礎(chǔ) . 中國水利水電出版社 , 2021 [3].

How nice my handkerchiefs look, don39。t they? Hannah washed and ironed them for me, and I marked them all myself, said Beth, looking proudly at the somewhat uneven letters which had cost her such labor. Bless the child! She39。s gone and put `Mother39。 on them instead of `M. March39。. How funny! cried Jo, taking one up. Isn39。t that right? I thought it was better to do it so, because Meg39。s initials are ., and I don39。t want anyone to use these but Marmee, said Beth。, looking troubled. It39。s all right, dear, and a very pretty idea, quite sensible too, for no one can ever mistake now. It will please her very much, I know, said Meg, with a frown for Jo and a smile for Beth. There39。s Mother. Hide the basket, quick! cried Jo, as a door slammed and steps sounded in the hall. Amy came in hastily, and looked rather abashed when she saw her sisters all waiting for her. Where have you been, and what are you hiding behind you? asked Meg, surprised to see, by her hood and cloak, that lazy Amy had been out so early. Don39。t laugh at me, Jo! I didn39。t mean anyone should know till the time came. I only meant to change the little bottle for a big one, and I gave all my money to get it, and I39。m truly trying not to be selfish any more. As she spoke, Amy showed the handsome flask w hich replaced the cheap one, and looked so earnest and humble in her little effort to fet herself that Meg hugged her on the spot, and Jo pronounced her `a trump39。, while Beth ran to the window, and picked her finest rose to ornament the stately bottle. You see I felt ashamed of my present, after reading and talking about being good this morning, so I ran round the corner and changed it the minute I was up, and I39。m so glad, for mine is the handsomest now. Another bang of the street door sent the basket under the sofa, and the girls to the table, eager for breakfast. Merry Christmas, Marmee! Many of them! Thank you for our books. We read some, and mean to every day, they all cried in chor us. Merry Christmas, little daughters! I39。m glad you began at once, and hope y ou will keep on. But I want to say one word before we sit down. Not far away from here lies a poor woman with a little newbor n baby. Six children are huddled into one bed to keep from freezing, for they have no fire. There is nothing to eat over there, and
