圖書信息管理系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)2摘要隨著信息技術(shù)在管理技術(shù)上越來越深入而廣泛的應(yīng)用，管理信息系統(tǒng)的實(shí)施在技術(shù)上已逐步成熟。管理信息系統(tǒng)是一個(gè)不斷發(fā)展的新型科學(xué)，任何一個(gè)單位要生存要發(fā)展，要高效率的把內(nèi)部活動(dòng)有機(jī)的組織起來，就必須建立與自身特點(diǎn)相適應(yīng)的管理信息系統(tǒng)。資料管理系統(tǒng)是典型的信息管理系統(tǒng)，其主要開發(fā)包括后臺(tái)數(shù)據(jù)庫的建立和維護(hù)，以及前端應(yīng)用程序的開發(fā)兩個(gè)方面。對(duì)于前者要求建立起數(shù)據(jù)庫一致性和完整性強(qiáng)，數(shù)據(jù)庫安全性好的庫。后者則要求應(yīng)用程序功能完備，易于使用等特點(diǎn)。因此，本人結(jié)合資料管理系統(tǒng)的要求，對(duì)易語言數(shù)據(jù)管理系統(tǒng)，易語言原理，易語言數(shù)據(jù)庫技術(shù)進(jìn)行了較深入的學(xué)習(xí)和應(yīng)用。主要完成對(duì)資料管理系統(tǒng)的要求分析、功能模塊劃分，并由此設(shè)計(jì)了數(shù)據(jù)庫結(jié)構(gòu)和應(yīng)用程序。系統(tǒng)運(yùn)行結(jié)果證明，本人設(shè)計(jì)的資料管理系統(tǒng)可滿足借閱者、資料管理工作人員和高級(jí)管理三方面的要求。系統(tǒng)開發(fā)采用大連飛揚(yáng)軟件工作室編寫的易語言，它是一種全中文全可視化電腦程序編寫語言。它的誕生結(jié)束了外國編程語言長期壟斷中國市場的局面，使中國人終于可以使用自己的母語來編寫各種實(shí)用電腦程序。利用易語言強(qiáng)大的可視化界面功能以及對(duì)數(shù)據(jù)庫的支持，先構(gòu)造一個(gè)模型，逐步增加功能，最終滿足需求，本系統(tǒng)界面友好，功能較強(qiáng)。不足的地方是當(dāng)數(shù)據(jù)庫訪問量大時(shí)，將導(dǎo)致性能的下降，且不利于數(shù)據(jù)庫有效共享，在以后改進(jìn)中應(yīng)考慮SERVER3作為數(shù)據(jù)庫，解決訪問速度及數(shù)據(jù)共享的問題。該系統(tǒng)力求易于使用，具有較高的擴(kuò)展性和可維護(hù)性。關(guān)鍵字：關(guān)系數(shù)據(jù)庫易語言資料管理系統(tǒng)系統(tǒng)開發(fā)信息系統(tǒng)SummaryAlongwithinformationtechniquemoreandmorethoroughbutextensiveapplicationinmanagingatechnique,managementinformationtheimplementofthesystemisonthetechniquealreadygraduallymature.Managingtheinformationsystemisanewsciencewhichdevelopscontinuously,thewhicheverunitwantstoexisttowantadevelopment,high-efficiencyoforganizeorganicallytheinternalactivity,havetobuildupadaptingwithoneselfcharacteristicsmutuallyofmanagementinformationsystem.Thedatamanagementsystemisatypicalinformationmanagementsystem,itmainlydevelopsestablishmentandmaintenanceofincludingthebackstagedatabase,andtheheadapplytheproceduredeveloptwoaspects.Starttobuildupthedatabaseconsistencyandtheintegritytotheformerrequeststrong,thedatabasesafetygooddatabase.Thelatterthenrequests4applyingprocedurefunctioniscomplete,beingeasytoanusageetc.characteristics.Therefore,oneselfcombineadatamanagementtherequestofthesystem,managesystemtotheeasylanguagedata,easylanguageprinciple,theeasylanguagedatabasetechniquecarriedonamorethoroughstudyandtheapplication.Mainlycompletetomanagesystemtothedataofrequestanalysis,functionmoldpiecedividetheline,anddesigneddatabasestructurefromhereandappliedprocedure.Thesystemcirculatesaresultcertificate,oneselfdesignofdatamanagementsystemcantheonewhosatisfytoborrowtoread,datamanagementthestaffmemberandhighclassmanagetherequestofthreeaspects.Word.AdoptionDalianofthesystemdevelopmentfloatsintheskytheeasylanguagethatthesoftwareutilityroomwrites,itisallofakindofwholeChinesesandcanseetoturncomputerproceduretowritelanguage.Itsbirthendedtheforeigncountryplaitdistancelanguagelong-termtobreakthesituationofChinesemarket,makingtheChinesecanuseanownmothertonguefinallytowritevariouspracticalcomputerprocedure.Makeuseofeasylanguagestrongofcanseetoturninterfacefunctionandtosupportofthedatabase,constructamodelfirst,increasefunctiongradually,endmeetthedemands,thissysteminterfaceisfriendly,thefunctionis5stronger.Whentheplaceofshortageistobeadatabaseinterviewstohasgreatcapacity,willcausethefunctiondescend,andthedisadvantageshareeffectivelyinthedatabase,shouldconsidertheSERVERasadatabaseinhereaftertheimprovement,resolvinginterviewspeedandthedatacommonlysharedproblem.Thatsystemtrieshardfortobeeasytoanusage,havingtoexpandsexhigherlyandcanningsupportsex.Keyword:TherelationdatabaseEasylanguageThedevelopmentinform
