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typically induces a certain measure of latency, so the timeliness dimension may suffer, with the data being slightly out of date.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	Process execution languages such as WS-BPEL aim at managing...	only the data flow.	incorrect	only the control flow.	incorrect	both the control and data flow.	correct	
MC	The federation pattern typically follows...	a push approach	incorrect	a pull approach	correct	
MC	Ideally, data integration should include...	only processes.	incorrect	only data.	incorrect	both processes and data.	correct	
MC	Enterprise Information Integration (EII) is an example of...	data propagation.	incorrect	data integration.	correct	data consolidation.	incorrect	data replication.	incorrect	
MC	Process execution languages such as WS-BPEL aim at managing...	both the control and data flow.	correct	only the data flow.	incorrect	only the control flow.	incorrect	
MC	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of...	data virtualization.	incorrect	data federation.	incorrect	data consolidation.	incorrect	data propagation.	correct	
MC	Which statement is NOT CORRECT?	Data virtualization extensively uses data consolidation techniques such as ETL.	correct	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	Data virtualization isolates applications and users from the actual (combinations of) data integration patterns used.	incorrect	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	
MC	Which statement is NOT CORRECT?	Analytics techniques are more and more used at the operational level as well by front-line employees.	incorrect	Nowadays, we see a complete divergence of the operational and tactical/strategic data needs and of the corresponding data integration tooling.	correct	Analytics for tactic/strategic decision making increasingly uses real-time operational data combined with the aggregated and historical data found in more traditional data warehouses.	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	Which statement is CORRECT?	Analytics for tactic/strategic decision making increasingly uses real-time operational data combined with the aggregated and historical data found in more traditional data warehouses.	correct	In a service oriented context, there is a tendency to physically integrate services with the purpose of task coordination with services that perform the actual task execution and services that provide access to the necessary data.	incorrect	Nowadays, we see a complete divergence of the operational and tactical/strategic data needs and of the corresponding data integration tooling.	incorrect	Process execution languages such as WS-BPEL aim at managing only the data flow.	incorrect
