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 CORRECT? Backup and recovery management is the task of the data steward. incorrect Backup and recovery management is the task of the database designer. incorrect Backup and recovery management is the task of the data scientist. incorrect Data stewards can undertake two types of actions to improve data quality: corrective measures and preventive measures. correct MC Is the following statement true or false? "Accuracy of a database depends on its representational and contextual characteristics." True correct False incorrect MC A data steward notices that part of the database contains values in a different language. Which type of data quality error is this? Representational correct Accessibility incorrect Contextual incorrect Intrinsic incorrect MC Why can data incompleteness prove to be useful information?

"Accuracy of a database depends on its representational and contextual characteristics." True correct False incorrect MC Which statement is NOT CORRECT? The four categories in which DQ dimensions can be grouped according to Wang et al. (1996) are: intrinsic, contextual, representation and access. incorrect Ideally, data governance should be set-up as a company-wide controlled and supported approach. incorrect The 4 steps in the Total Data Quality Management framework of Wang (1998) are: define, measure, analyze and implement. correct Data quality is very contextual. incorrect MC Which statement is CORRECT?
