至于“DatamodelsarecomponentsofaMetadatarepository.”，數(shù)據(jù)模型的確是元數(shù)據(jù)存儲(chǔ)庫(kù)的內(nèi)容之一，大家也不要去追究這個(gè)選項(xiàng)講得不完整，DAMA的題都一樣，但至少比其它幾個(gè)選項(xiàng)要好，至少?zèng)]錯(cuò)。40.TheMetadatarepositoryenablesustoestablishmultipleperspectivesofdata.Theseare:A、InternalandexternalB、TheBusinessandTechnicalPerspectiveC、Dimensionalandnon-dimensionalperspectiveD、3rdnormalformandun-normalisedE、Structuredandunstructured答案：B解析：三種主要元數(shù)據(jù)類型，業(yè)務(wù)元數(shù)據(jù)，技術(shù)元數(shù)據(jù)，操作元數(shù)據(jù)。41.Tocontinuallyimprovethequalityofdataandinformationanorganizationmustconsiderwhichoneofthefollowing？A、Theclarityandsharedacceptanceofdatadefinitions.B、MaximizetheeffectiveuseandvalueofdataandinformationassetsC、Controlthecostofdatamanagement.D、UnderstandtheinformationneedsoftheenterpriseanditsstakeholdersE、All答案：A42._________governanceconsistsofaddressingacurrentcriticalissueA、PerformanceB、CentralC、Pre-emptiveD、ProtectiveE、Reactive答案：E43.Asearchenginedatabaseispopulatedbyawebcrawlerorspidersoftwarethatusuallyprocessesas:A、Linearlyindependent,nearexact(LINE)B、Fundamentallyavailable,consistentlytrue(FACT)C、Atomic,consistent,isolated,durable(ACID)D、Basicallyavailable,softstate,eventually,consistent(BASE)E、Continuallyrepeating,alwaysperforming(CRAP)答案：D解析：ACID和BASE是兩個(gè)對(duì)立體，BASE強(qiáng)調(diào)擴(kuò)展，更適合互聯(lián)網(wǎng)見(jiàn)P27344.Agoalof'DocumentandContentManagement'istoensureeffectiveandefficientretrievalanduseof:A、data,butnotinformationinunstructuredformats.B、information,butnotdatainunstructuredformats.C、Dataandinformationinstructuredformats.D、Dataandinformationinunstructuredformats.E、Dataandinformationinrelationalformats.答案：D解析：文件是非結(jié)構(gòu)化數(shù)據(jù)45.InDimensionaldatamodels,whichoftheseisNOTtrueregardingMeasuresA、MeasuresarefoundinFacttablesB、CaremustbetakenifameasureisasnapshotfigureC、MeasurescanalwaysbeaddedacrossalldimensionsD、MeasuresshouldbenumericandadditiveE、Justbecauseavalueisnumericaldoesnotmeanitisameasure答案：C解析：該題考的是維度建模，稍后我做個(gè)完整的視頻解釋，這里稍作簡(jiǎn)述。Measurescanalwaysbeaddedacrossalldimensions：中的維度表，某種意義上來(lái)說(shuō)，跟參考數(shù)據(jù)是同義的，如地區(qū)維表，這里表是不能累加的，也不含指標(biāo)相關(guān)的內(nèi)容的，也不能單獨(dú)使用，必須和事實(shí)表關(guān)聯(lián)才能使用的。MeasuresarefoundinFacttables：事實(shí)表就是記錄過(guò)程數(shù)據(jù)的，如訂單數(shù)據(jù)，所以是可以找到指標(biāo)相關(guān)的信息的Caremustbetakenifameasureisasnapshotfigure：這種中性描述，沒(méi)錯(cuò)，雖然沒(méi)把原因?qū)懗鰜?lái)剩下兩個(gè)答案：指標(biāo)是累加的數(shù)值（請(qǐng)參閱《華為數(shù)據(jù)之道》）46.Inadatawarehouse,wheretheclassificationlistsfororganizationtypeareinconsistentindifferentsourcesystemsthereisanindicationthatthereisalackoffocusonA、ReferencedataB、MetadataManagementC、DataModellingD、DataStorageE、Masterdata答案：A解析：組織架構(gòu)屬參考數(shù)據(jù)在DAMA中，若見(jiàn)到分類這種詞語(yǔ)，一般就指參考數(shù)據(jù)47.DatagovernancediffersfromitgovernanceinthatA、Seriousproblemscanoccurintheprojectcycle,andafteroperationalizedversusupfrontfeaturesanalysisanddesignintechnologyprojectsB、YoubuyanddeploysolutionsatincreasinglevelsofspecificationthroughtheprojectC、Seriousproblemscanbediscoveredatanyleveloftheorganizationversustop-downidentificationofrisksandissuesintechnologyD、NosinglegrouphascontrolofdataasitflowsthroughouttheorganizationversussingleownerassignmentoftechnologyE、None答案：D解析：該題用排除法，除了所選答案外，其余均是IT治理內(nèi)容，與數(shù)據(jù)治理無(wú)關(guān)，題目是讓我們選擇數(shù)據(jù)治理的解釋48.AdataownerhasresponsibilityandauthorityforA、AllB、Quality,access,distributionandbusinessdefinitions.C、BusinessdefinitionsanddatasecuritymanagementD、Regulationspolicies,knowledgeofdataprivacylaws,businessrulesandbusinessobjectivesE、Distributionsandretentionofdata答案：B49.Thedeliverablesforadatamodellingprocessdoesnothavetoinclude:A、LineagedescribingwherethedatacamefromB、IssuesandoutstandingquestionsC、OneormorediagramsD、ThestepsinthebusinessprocessthatusethedataE、Definitionsforentities,attributesandrelationships答案：D解析：Thestepsinthebusinessprocessthatusethedata：應(yīng)該是業(yè)務(wù)架構(gòu)要交付的內(nèi)容50.Forbusinessintelligence,businessdatastewardshelpwithallofthefollowingEXCEPTA、DataqualityMetricsB、BIrequirementsC、BIissueD、ManagementmetricsE、Dimensionalmodeldevelopment答案：E51.Whatarerelationshiplabels?A、Arelationshipwithoutcardinality.B、Theverbphrasesdescribingthebusinessrulesineachdirectionbetweentwoentities.C、Aforeignkeythathasbeenrole-named.D、Thenullabilitysettingonaforeignkey.E、Anon-identifyingrelationship.答案：B解析：請(qǐng)P202，relationship，指兩個(gè)實(shí)體之間的關(guān)聯(lián)關(guān)系。52.Adatalineagetoolenablesauserto:A、Enablesrapiddevelopmentofdashboardreporting.B、Lineupthedatatosupportsophisticatedglossarymanagement.C、Visualisehowthedatagetstothedatalake.D、Trackthedatafromsourcesystemtoatargetdatabase;understandingitstransformations.E、Trackthehistoricalchangestoadatavalue.答案：D解析：請(qǐng)見(jiàn)P245，書(shū)上的定義：53.De-identifyingsensitivedatainadatawarehouseenables：A、CertaintyofcompletedatasetsforinterrogationB、AbypassintheneedtoassessdataqualityC、AreducedcomplexityinthedatamodelsD、IncreasedutilizationwithoutcompromisingdataprivacyE、Afocusonre-identifyingrecordswith3rdpartydatasets答案：D解析：見(jiàn)P3

維表有兩個(gè)特征：（1）字段（列）數(shù)量大：如會(huì)員，可能會(huì)有二、三十個(gè)字段（2）維表記錄數(shù)與事實(shí)表比不大，如阿里巴巴的會(huì)員記錄可能十億行（維表），但事實(shí)表（交易記錄）估計(jì)已經(jīng)超過(guò)萬(wàn)億行。我拿阿里來(lái)舉例，是因?yàn)榘⒗锘敬砹司S度建模的金字塔頂端。實(shí)際上更多的情況是一千幾百個(gè)產(chǎn)品，數(shù)百萬(wàn)行交易記錄。

切記，這里提的多與少，是維表與事實(shí)表作比較，千萬(wàn)不要與主數(shù)據(jù)及參考數(shù)據(jù)一同分析，這是兩個(gè)概念。67.Discoveringanddocumentingmetadataaboutphysicaldataassetsprovides:A、EffectiveprojectscopemanagementB、AnestimationofbalancesheetvalueofenterprisedataC、InformationonhowdataistransformedasitmovesbetweensystemsD、InsightsintothetemporaldataqualityE、Scopingboundariesofthedatadictionary答案：C解析：見(jiàn)P636，該題考的是數(shù)據(jù)血緣，68.Inadatawarehouse,wheretheclassificationlistsfororganizationtypeareinconsistentindifferentsourcesystemsthereisanindicationthatthereisalackoffocusonA、DataStorageB、MasterdataC、MetadataManagementD、DataModellingE、Referencedata答案：E解析：組織架構(gòu)屬參考數(shù)據(jù)在DAMA中，若見(jiàn)到分類這種詞語(yǔ)，一般就指參考數(shù)據(jù)69.Referencedataisusedto:A、EnforceenterprisesecuritystandardsB、PopulatefacttablesinadatamartC、CategorizeorclassifydataD、DescribebackupstrategiesE、Removeduplicatecustomerrecords答案：C解析：參考數(shù)據(jù)，如地區(qū)等，某種意義上來(lái)說(shuō)，是把事實(shí)數(shù)據(jù)按地區(qū)進(jìn)行切片（或者說(shuō)歸類）70.Bysetting,enforcingandauditingmetadatastandards,organizationshopeto:A、StandardizebusinessrulesinoperationalprocessesB、EaseofunderstandingdatadictionariesC、Ensuretheappropriateclassificationormeta-metadataD、SimplifyintegrationandenableuseE、Provideactivitiesforthedatagovernanceoffice答案：D解析：見(jiàn)P60871.WhichofthefollowingBESTdescribestheroleofadataintermediary？A、SomeonewhodecideswhatdataisimportanttothebusinessB、AllC、SomeonewhoisresponsiblefortranslatingbusinessrequirementsintoadatabasedesignD、Someonewhoisresponsibleformanagingthemeta-datarepositoryE、Someonewhoreceivesdatainoneformandtranscribesitintoanotherfor答案：E72.WhichofthefollowingisNOTaprimaryMasterDataManagementareaoffocus?A、IdentifyingduplicaterecordsB、ProducingreadonlyversionsofkeydataitemsC、Generatingagoldenrecord/bestversionofthetruthD、ProducingcleardatadefinitionsforMasterDataE、Providingaccesstogoldendatarecords答案：B解析：B類型題目，相關(guān)的書(shū)上的介紹請(qǐng)見(jiàn)P518，我截圖如下：并未見(jiàn)到提及“Producingreadonlyversionsofkeydataitems”73.AcharacteristicofinformationqualitythatmeasuresthedegreeofthedatagranularityisknownA、AggregationB、DatasetC、ScaleD、Precision答案：D74.Anapplicationusesasingleserviceaccountforalldatabaseaccess.Oneoftherisksofthisapproachis:A、ItconstrainstheapplicationfromrunningparallelprocessesB、ThedatabaserunsoutofthreadsC、TheapplicationfreezesmoreoftenD、TheabilitytotracewhomadechangestothedataE、Thedatabecomesoutoforder答案：C解析：serviceaccount指的是非操作人員帳戶，如SQLSERVER中的SYSTEM帳戶等，他們是沒(méi)有密碼的；如果所有數(shù)據(jù)庫(kù)都用一個(gè)serviceaccount，如dev，prd，uat，那假設(shè)其中某個(gè)地方引致這個(gè)account出現(xiàn)問(wèn)題（如拒絕訪問(wèn)WINDOW的某個(gè)目錄，而這個(gè)目錄剛好是保存數(shù)據(jù)的父目錄），將會(huì)出現(xiàn)所有環(huán)境不能訪問(wèn)；又或者在修改后臺(tái)服務(wù)帳戶權(quán)限后，導(dǎo)至前臺(tái)桌面應(yīng)用不能訪問(wèn)（Tableau會(huì)有此問(wèn)題）
