MC	A data steward notices that part of the database contains values in a different language. Which type of data quality error is this?	Accessibility	incorrect	Contextual	incorrect	Representational	correct	Intrinsic	incorrect	
MC	Which statement is NOT CORRECT?	Data quality can always be measured objectively.	correct	Consistency issues can arise due to sharing data across multiple departments.	incorrect	All aspects of data quality need to be checked regularly, as every change in the database or even the company can lead to unforeseen issues.	incorrect	Subjectivity can cause data quality issues.	incorrect	
MC	Why can data incompleteness prove to be useful information?	We can track down faults in the database model, such as updating errors that cause inconsistencies.	incorrect	We can track down the source of the incompleteness and thereby eliminate the cause thereof.	incorrect	We can track down certain patterns in the incomplete fields, which can lead to more information about a certain user.	incorrect	All of the above.	correct	
MC	Which statement is CORRECT?	The catalog forms the heart of a database.  It can be an integral part of the DBMS or a standalone component.  	incorrect	The catalog makes sure the database continues to be correct by, amongst others, specifying all integrity rules.	incorrect	The catalog describes all metadata components that are defined in the metamodel.	incorrect	All of these statements are correct.	correct

MC	Which statement is NOT CORRECT?	Poor data quality only affects organizations in their operational processes. 	correct	The DQ dimension 'Accuracy' is often heavily correlated with other DQ dimensions.	incorrect	The catalog should keep statistics on the data and its usage.	incorrect	The catalog should provide facilities to import and export data definitions.	incorrect	
MC	Is the following statement true or false? "Accuracy of a database depends on its representational and contextual characteristics."	False	incorrect	True	correct

MC	Which statement is NOT CORRECT?	The catalog can be used to enforce integrity rules to ensure that the database is in a consistent and correct state at all times.	incorrect	Ideally, data governance should be set-up as a company-wide controlled and supported approach.	incorrect	A partial short term solution for data quality improvement can be achieved by annotating data with explicit information about its quality in the catalog.	incorrect	In a data quality context, 'Fitness for use' implies that the data should be of perfect quality in all decision contexts.	correct
