MC	Which statement is NOT CORRECT?	An ETL process typically induces a certain measure of latency, so the timeliness dimension may suffer, with the data being slightly out of date.	incorrect	An important disadvantage of the consolidation approach is that it does not cater for historical data.	correct	Besides the traditional set-up with ETL and a data warehouse, data lakes can also be considered an implementation of the consolidation pattern. 	incorrect	The essence of data consolidation as a data integration pattern is to capture the data from multiple, heterogeneous source systems and integrate it into a single persistent store (e.g., a data warehouse or data mart). 	incorrect

MC	Which statement is NOT CORRECT?	Analytics techniques are more and more used at the operational level as well by front-line employees.	incorrect	Contrary to a federated database as offered by basic EII, data virtualization does not impose a single data model on top of the heterogeneous data sources.	incorrect	The choreography pattern to manage sequence and data dependencies is a centralized approach.	correct	Enterprise Information Integration (EII) is an example of data integration.	incorrect	
MC	Which statement is CORRECT?	It makes no sense to look at HTML markup when calculating the weight of a term to a page for web search. 	incorrect	An important disadvantage of the consolidation approach is that it does not cater for historical data.	incorrect	Data virtualization extensively uses data consolidation techniques such as ETL.	incorrect	The data flow perspective of a business process focusses on the inputs of the tasks (e.g., the interest rate offered depends on the credit score). 	correct	
MC	Which statement is NOT CORRECT?	Enterprise Information Integration (EII) is an example of data consolidation.	correct	Data virtualization isolates applications and users from the actual (combinations of) data integration patterns used.	incorrect	Process integration is to integrate and harmonize the various business processes in an organization as much as possible.	incorrect	Ideally, data integration should include both processes and data.	incorrect	
MC	Which statement is CORRECT?	Data virtualization extensively uses data consolidation techniques such as ETL.	incorrect	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of data federation.	incorrect	Enterprise Information Integration (EII) is an example of data integration.	correct	Enterprise Information Integration (EII) is an example of data propagation.	incorrect
