object in a query.A condition created in theDesignermodule is referred to as apredefinedcondition.6.ConnectionSet of parameter that provides access to an RDBMS. These parameters includesystem information such as the data account, user identification, and path to thedatabase. Designer provides three types of connections: secured, shared, andpersonal.7.Context

10.DocumentdomainThe area of the repository that stores documents, templates, scripts, and lists ofvalues.

11.Drill A: -Theactionofnavigatingthrough levelsofdata.Whenyoudrillup, youobtainmore summarized or general information. By drilling down, you can reach morerefinedordetailedinformation.12.Equi-join

Ajoinbasedon theequalitybetweenthevaluesin thecolumnofonetableand thevaluesinthecolumnofanother.Becausethesamecolumnispresentinbothtables,thejoinsynchronizesthetwotables.13.Enterprisemode A: -Aworkmodewherebyadesignercreatesuniversesinanenvironmentwitharepository. The mode in which a universe is saved determines whether otherdesignersareabletoaccessit.Bydefault,auniverseissavedinthemodeinwhichthedesignerisalreadyworking.

14.Hierarchy Anorderedseriesofrelateddimensionsusedformultidimensionalanalysis.15.Join A: -A relational operation that causes two tables with a common column to becombined intoasingle table.Designersupportsequi-joins, theta joins,outer joins,andshortcutjoins.

18.Measureobject A: - An object that is derived from an aggregate function. It conveys numericinformationbywhichadimensionobjectcanbemeasured.

19.Object A:-Acomponentthatmapstodataoraderivationofdatain thedatabase.Forthepurposesofmultidimensionalanalysis, anobject can bequalified asadimension,detail,ormeasure.Objectsaregroupedintoclasses.20.OfflinemodeTheworkmodeinwhichthedesignerworkswithuniversesstoredlocally.21.Onlinemode

A:-The workmode appropriate for a networked environment in which the generalsupervisorhassetuparepository.22.Outerjoin A:-Ajointhat linkstwotables,oneofwhichhasrowsthatdonotmatchthoseinthecommoncolumnoftheothertable.23.Personalconnection

Apersonalconnectionisusedtoaccessresourcessuchasuniversesordocuments.It can be used only by the user who created it. Information about a personalconnectionisstoredinboththePDAC.LSIandPDAC.SSIfiles;itsdefinitionisstaticandcannotbemodified.24.Qualification A:-Apropertyof anobject thatdetermineshow it canbeused inmultidimensionalanalysis. Anobject can bequalified asone of three types: a dimension, detail ormeasure.

25.QueryIn Designer a query is a technique for creating or modifying a list of valuesassociatedwithanobject.FromtheQueryPanel,adesignerbuildsaqueryfromtheclasses,objects,andconditionsofauniverse.IntheBusinessObjectsUsermodule,aqueryisatypeofdataprovider.Anenduserbuilds a query from a universe, and then runs the query to generate aBusinessObjectsreport.26.QuickDesign

A wizard in the Designermodule that provides guided instructions for creating abasic universe. It lets a designer name a universe, set up a connection to a

database, select strategies,create classesand objects,aswell asgenerate joinswithcardinalities.27.Repository

A centralized set of relational data structures stored in a database. It enablesBusinessObjectsuserstoshareresourcesinacontrolledandsecuredenvironment.The repository is made up of three domains: the security domain, the universedomain,andthedocumentdomain.28.Securedconnection A secured connection is used to access universes or documents that may berestrictedorconfidential.Itcanbesharedbyseveralauthorizedusers.Storedintherepository,thedefinitionofasecuredconnectionisupdateddynamically.

29.Sharedconnection A shared connection is used to access common resources such as universes ordocuments.Itcanbeusedbyseveralusers.InformationaboutasharedconnectionisstoredinaSDAC.LSIorSDAC.SSIfile;itsdefinitionisupdateddynamically.30.Shortcutjoin A:-Ajointhatlinkstwotablesbybypassingoneormoreothertablesintheuniverse.

31.Strategy A:-Scripts that automatically extract structural information about tables, columns, joins, or cardinalities from a database. Designer provides default strategies but adesignercanalsocreatestrategies.Thesearereferredtoasexternalstrategies.32.Structurepane A:-The graphical component within the main Designer window that shows theschemaoftheuniverse.Itreflectstheunderlyingdatabasestructureoftheuniverse.

33.Subclass A:-A component within a class that groups objects. A subclass can itself containothersubclassesorobjects.34.TableBrowserThegraphicalcomponentwithinthemainDesignerwindowthatletsyoucreatetheclassesandobjectsoftheuniversefromthetablesandcolumnsofadatabase.35.Thetajoin

A join that links tables based on a relationship other than equality between twocolumns.36.Universe

Amappingof thedatastructure found indatabases: tables,columns, joins,etc.Auniverse,whichismadeupofclasses,objects,andconditions,can represent anyspecificapplication,system,orgroupofusers.37.UniversedomainThe area of the repository that holds exported universes. The universe domainmakes it possible to store, distribute, and administrate universes. There may bemultipleuniversedomainsinarepository.38.Universepane

A:-The graphical component within the main Designer window that displays ahierarchicalviewoftheclasses,objects,andconditionsinauniverse.Tworadiobuttonsontheloweredgeofthepanefilterthedisplayofthecomponents.Onebutton, theClasses/Objects filter, providesaviewoftheclassesandobjects.Theotherbutton,Classes/Conditions,providesaviewoftheclassesandconditions.39.Userobject Anobjectcreatedby theenduser from theBusinessObjectsUsermodule.Auserobjectcanbeinsertedintoauniversebythedesigner.

40.Workgroupmode A:-Aworkmodewherebyadesignercreatesuniversesinanenvironmentwithoutarepository. The mode in which a universe is saved determines whether otherdesignersareabletoaccessit.Bydefault,auniverseissavedinthemodeinwhichthedesignerisalreadyworking.41.WhatisDesigner?

Aswith the firstphase, you should test theintegrity of your universe structure. You may also wish to perform tests on the

universes you create from the BusinessObjects User module. Finally, you candistributeyouruniversestousersbyexportingthemtotherepositoryorviayourfilesystem.For a universe based on a simple relational schema, Designer provides QuickDesign, a wizard for creating a basic yet complete universe. You can use theresultinguniverse immediately, oryou canmodify theobjectsand create complexnew ones. In this way, you can gradually refine the quality and structure of youruniverse.43.Howdoyoudefineuniverseparameters?

@PromptSyntax@Prompt('message',['type'],[lov],[MONO|MULTI],[FREE|CONSTRAINED])message is the text of a message within single quotes. type can be one of thefollowing:'A'foralphanumeric,'N'fornumber,or'D'fordate.lov can be either a listof values enclosed in brackets (each value must be within single quotes andseparatedbycommas)orthenameofaclassandobjectseparatedbyabackslashandwithinsinglequotes. MONOmeans that the prompt accepts only one value.MULTImeansthatthepromptcanacceptseveralvalues.
