圖書信息管理系統(tǒng)的設計與實現(xiàn)2摘要隨著信息技術在管理技術上越來越深入而廣泛的應用，管理信息系統(tǒng)的實施在技術上已逐步成熟。管理信息系統(tǒng)是一個不斷發(fā)展的新型科學，任何一個單位要生存要發(fā)展，要高效率的把內部活動有機的組織起來，就必須建立與自身特點相適應的管理信息系統(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)包括后臺數(shù)據(jù)庫的建立和維護，以及前端應用程序的開發(fā)兩個方面。對于前者要求建立起數(shù)據(jù)庫一致性和完整性強，數(shù)據(jù)庫安全性好的庫。后者則要求應用程序功能完備，易于使用等特點。因此，本人結合資料管理系統(tǒng)的要求，對易語言數(shù)據(jù)管理系統(tǒng)，易語言原理，易語言數(shù)據(jù)庫技術進行了較深入的學習和應用。主要完成對資料管理系統(tǒng)的要求分析、功能模塊劃分，并由此設計了數(shù)據(jù)庫結構和應用程序。系統(tǒng)運行結果證明，本人設計的資料管理系統(tǒng)可滿足借閱者、資料管理工作人員和高級管理三方面的要求。系統(tǒng)開發(fā)采用大連飛揚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用電腦程序。利用易語言強大的可視化界面功能以及對數(shù)據(jù)庫的支持，先構造一個模型，逐步增加功能，最終滿足需求，本系統(tǒng)界面友好，功能較強。不足的地方是當數(shù)據(jù)庫訪問量大時，將導致性能的下降，且不利于數(shù)據(jù)庫有效共享，在以后改進中應考慮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，具有較高的擴展性和可維護性。關鍵字：關系數(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
