MC	Which statement is NOT CORRECT?	An important disadvantage of the consolidation approach is that it does not cater for historical data.	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typically induces a certain measure of latency, so the timeliness dimension may suffer, with the data being slightly out of date.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	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	Besides the traditional set-up with ETL and a data warehouse, data lakes can also be considered an implementation of the consolidation pattern. 	incorrect	
MC	Which statement is NOT CORRECT?	Enterprise Information Integration (EII) is an example of data propagation.	correct	Ideally, data integration should include both processes and data.	incorrect	The focus of MDM is on unifying company-wide reference data types such as customers and products.	incorrect	The operational usage of business intelligence aims for a low (or even zero) latency so interesting events or trends in the data can be immediately detected and accompanied with the appropriate response.	incorrect	
MC	Ideally, data integration should include...	only data.	incorrect	both processes and data.	correct	only processes.	incorrect	
MC	The choreography pattern to manage sequence and data dependencies is a...	centralized approach.	incorrect	decentralized approach.	correct	
MC	Process execution languages such as WS-BPEL aim at managing...	only the data flow.	incorrect	both the control and data flow.	correct	only the control flow.	incorrect	
MC	The federation pattern typically follows...	a push approach	incorrect	a pull approach	correct	
MC	Enterprise Information Integration (EII) is an example of...	data consolidation.	incorrect	data replication.	incorrect	data integration.	correct	data propagation.	incorrect	
MC	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of...	data federation.	incorrect	data propagation.	correct	data virtualization.	incorrect	data consolidation.	incorrect	
MC	Which statement is NOT CORRECT?	Data virtualization isolates applications and users from the actual (combinations of) data integration patterns used.	incorrect	Data virtualization extensively uses data consolidation techniques such as ETL.	correct	In many real-life contexts, a data integration exercise is an ongoing initiative within an organization, and will often combine a variety of integration strategies and approaches.	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
