毕业论文 外文翻译 用于连锁酒店预订管理信息系统需求分析的uml方法

译文用于连锁酒店预订管理信息系统需求分析的UML方法摘要本文介绍了在开发酒店预订管理系统时，用于需求分析阶段的UML方法的实施过程。UML用例和VISIO2003是用来分析和实现的工具。通过采用图形化的方法，包括用例视图、交互视图、序列视图、状态视图，能够把原始的用户们多种多样的需求整理好，并且有效和详细地阐述出来。因此，这些结果为系统的后续开发和实施提供有效的基础。关键词组件，设计，UML，连锁酒店管理系统，需求分析，用例，试图。1引言传统的需求分析，重点放在系统和功能的阐述分析。它是专注于单个模块功能的过程。它使得系统分析很容易被复杂的系统功能弄得混乱，而且还缺少对整体框架的认识，即系统和需求视图的逻辑结构。所有的这些缺陷造成了所设计的系统缺少一个清楚的架构，而且还降低了系统的灵活性和扩展性。随着面向对象的分析与设计（OOAONTHECONTRARY,WHENTHERECEPTIONISTRECEIVESACALLFROMACUSTOMER,HEMUSTCHECKINTHEROOMSTATEMAP,CONDUCTINGTHEINFORMATIONREGISTRATIONOFTHECALLINGCUSTOMERTOFULFILLTHEPHONERESERVATIONTHEUSECASEDIAGRAMOF“RESERVATIONMANAGEMENT”ISPICTUREDASFIGURE2FIG2INTENDEDUSECASEDIAGRAMAFTERTHECUSTOMERLOGSINTHEINTERFACEOFRESERVATION,IFHEISTHEMEMBEROFTHEHOTELWOULDBEASKEDTOINPUTTHEMEMBERNUMBERANDPASSWORD,THENTHESYSTEMWILLPROVIDEHISINFORMATIONIMMEDIATELYTHESELECTREGIONANDTIMEARETHETWONECESSARYUSECASESTOENSURETHEFOLLOWINGRESERVATIONOPERATIONNAMELY,THEONLINERESERVATIONINCLUDESSELECTREGION,SELECTTIMEANDMEMBERREGISTRATIONUSECASE,ANDMAKEUSEOFTHEUSECASEOFROOMINQUIRYTOCHECKTHEFUNCTIONFIG3INTENDEDUSECASEDIAGRAM32EXTENSIVEREFERRINGUSECASEINTERACTIONVIEWACOLLABORATIONDIAGRAMSHOWSTHEOBJECTSANDRELATIONSHIPSINVOLVEDINANINTERACTIONFIG4SCHEDULEDINTERACTIVEDIAGRAM33EXTENSIVEREFERRINGUSECASEACTIVEVIEWACTIVEDIAGRAMISTHECONTROLFLOWTHATDESCRIBESARANGEOFACTIVITIESOFSYSTEMANDBUSINESS,WHICHDEMONSTRATESTHEWHOLEPROCESSTHATTRANSFERSONEACTIVITYTOANOTHERACTIVEDIAGRAMISASPECIALSTATEMACHINE,WHICHCONTAINSMOSTPARTSOFACTIVESTATE,MOSTTRANSFORMATIONARETRIGGEREDBYTHECOMPLETIONOFTHEORIGINALSTATEACTIVITYTHEELEMENTSOFTHEACTIVEDIAGRAMCONSISTOFOPERATINGSTATE,ACTIVESTATE,TRANSFORMATION,BRANCH,FORK,CONNECTION,ANDTRACKANDOBJECTFLOWOPERATINGSTATEINDICATESEXECUTABLEANDINSEPARABLEACTIONEXECUTIONFOREXAMPLE,TOCALCULATEASSIGNMENTOFATTRIBUTION,INVOKEANOBJECT,SENDASIGNALTOTHEOBJECT,ORBUILDANDDAMAGEANOBJECT,ANDSOONWHILEACTIVESTATEISOPPOSITETOTHEACTIVESTATE,ITCANBEDECOMPOSEDOPERATINGSTATEISANEXCEPTIONFROMTHEACTIVESTATEFORITCANTBEDECOMPOSEDFURTHERMOREACTIVEDIAGRAMPROVIDESTHEDESCRIPTIONOFSYSTEMAFTERTHEUSECASEDIAGRAM,TOEXPLAINMOREABOUTTHEEXECUTIONPROCESSOFSYSTEM,ANDHOWTOCHANGETHEDIRECTIONOFEXECUTIONINVARIOUSSITUATIONSTHEREFORE,ACTIVEDIAGRAMISUSEDTOBUILDWORKCONTROLFLOWFORTHEUSECASEMODEL,TOELABORATETHEUSECASEMODELFIG5SCHEDULEDACTIVITYDIAGRAM34EXTENSIVEREFERRINGUSECASESEQUENCEVIEWSEQUENCEDIAGRAMMODELSUSEADOPTEDLOGICALPROPOSAL,THEADOPTEDPROPOSALCANBEAPARTOFUSECASECANBETHEOPTIONALPROCESSCANBETHEWHOLEUSECASEPROCESSITALSOCANBETHELOGICINVOLVINGINSEVERALUSECASESSEQUENCEDIAGRAMBELONGSTOSOMEINTERACTIONAMONGBEHAVIORALCLASSIFIERCLASSIFIERISCOLLABORATIONONECOLLABORATIONCANINVOLVESEVERALINTERACTIONSHOWEVER,ONEINTERACTIONCANONLYINVOLVEONESEQUENCEDIAGRAMTHISISTHERESERVATIONSEQUENCEDIAGRAMOFTHECHAINHOTELRESERVATIONMANAGEMENTFIG6SCHEDULEDSEQUENCEDIAGRAM4FEATUREREQUIREMENTINORDERTOENSURETHELASTING,SAFE,STABLE,RELIABLEANDEFFECTIVEOPERATION,“CHAINHOTELMANAGEMENTSYSTEM”SHOULDMEETTHEFOLLOWINGASPECTSOFFEATUREREQUIREMENT41DATADEFINITIONSYSTEMOFDATAPROCESSINGACCURACYANDPRECISIONREQUIREMENTSSHALLBESATISFIEDASFOLLOWSAASTHEINPUTGENERATEDBYTHESYSTEMMUSTMEET18BREQUIREDITEMMUSTHAVESIGNS,ANDEMAILADDRESSWHICHINPUTMUSTCONFORMTOTHEFORMOFEMAILADDRESSCINTEGERNUMBERSHOULDBERETAINEDONTHEUNITSDTHEREALDATADONOTSPECIALREQUIREMENTGENERALLYRETAINEDAFTERTHEDECIMALPOINTTWO42CHARACTERISTICSOFTHETIMEANDADAPTABILITYSYSTEMPROCESSINGACCURACYANDTIMELINESSISTHESYSTEMPERFORMANCENECESSARYINTHESYSTEMDESIGNANDDEVELOPMENTPROCESS,MUSTFULLYCONSIDERWHATWILLTHESYSTEMBEEXPOSEDTOCURRENTANDFUTUREWORKLOAD,THESYSTEMSPROCESSINGPOWERANDRESPONSETIMETOMEETTHENEEDSOFUSERSOFINFORMATIONPROCESSING“CHAINHOTELMANAGEMENTSYSTEM“INTHEDAILYTREATMENTRESPONSERATEOF1SECONDGRADE,SOITCANBETIMELYFEEDBACKDURINGTHETIMEOFSTATISTICALANDANALYSISANDQUERY,ACCORDINGTOTHEDIFFERENTAMOUNTOFDATAREQUIRED,THEDIFFERENTOFSECONDGRADETOTHEMINUTELEVELPRINCIPLEISTOENSURETHATOPERATORSWILLNOTAFFECTTHESPEEDOFEFFICIENCYINTHEPROCESSOFDEVELOPING“CHAINHOTELMANAGEMENTSYSTEM”,EXPANDABILITYSHOULDBETAKENINTOCONSIDERATIONFOREXAMPLE,WITHTHECHANGEINTHEWAYOFMANAGEMENTSYSTEM,USERSDEMANDFORINQUIRYWILLALSOBECONTINUOUSLYUPDATEDANDCOMPLETEDALLOFTHESEREQUESTTHESYSTEMTOPROVIDESUFFICIENTWAYSINADJUSTINGANDEXPANDINGTHEFUNCTION4THISSHOULDBEREALIZEDTHROUGHTHEOPENNESSOFTHESYSTEMTHATIS,SYSTEMSHOULDBEOPENASWELLASBEABLETOINCREASEANDDECREASESYSTEMMODULESIMPLYANDDEPLOYSYSTEMHARDWAREONTHEPREMISEOFCOMPLYINGWITHCERTAINSTANDARDTHROUGHFIXINGANDREPLACINGTHESOFTWARE,THEPROMOTIONANDUPDATEOFSYSTEMISCOMPLETEDTHESYSTEMASSURESITSEASINESSINAPPLICATIONANDMAINTENANCETHEUSERS“CHAINHOTELMANAGEMENTSYSTEM”DIRECTLYDEALSWITHARENOTCOMPUTERPROFESSIONALS,WHICHCALLSFORTHESYSTEMTOPROVIDEFAVORABLECUSTOMERINTERFACEANDFRIENDLYHUMANCOMPUTERINTERACTIONINTERFACETOREALIZETHIS,ITREQUIRESTHESYSTEMTOUSETECHNICALTERMSTHATAREFAMILIARTOUSERSANDINTERFACEOFCHINESEINFORMATIONASMUCHASPOSSIBLETOAIMATPOSSIBLEHANDLINGPROBLEMSUSERSMAYCOMEACROSS,SUFFICIENTONLINEHELPSHOULDBEPROVIDED,SHORTENINGTHEPROCESSOFTHEUSERSFAMILIARIZATIONWITHTHESYSTEM5FIG7SCHEDULEDACTIVITYDIAGRAMALOGINSCREENWHENSTARTUPPROGRAM,THELOGINSCREENWILLB
