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	Ideally, data integration should include...	only processes.	incorrect	only data.	incorrect	both processes and data.	correct	
MC	Which statement is CORRECT?	Enterprise Information Integration (EII) is an example of data propagation.	incorrect	Enterprise Information Integration (EII) is an example of data replication.	incorrect	The prevalent approach for indexing full text documents is an inverted index.	correct	The choreography pattern to manage sequence and data dependencies is a centralized approach.	incorrect	
MC	Which statement is NOT CORRECT?	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	Data virtualization isolates applications and users from the actual (combinations of) data integration patterns used.	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	
MC	The federation pattern typically follows...	a pull approach	correct	a push approach	incorrect	
MC	Which statement is NOT CORRECT?	Process execution languages such as WS-BPEL aim at managing only the data flow.	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	Analytics techniques are more and more used at the operational level as well by front-line employees.	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 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	Process execution languages such as WS-BPEL aim at managing only the data flow.	incorrect	Nowadays, we see a complete divergence of the operational and tactical/strategic data needs and of the corresponding data integration tooling.	incorrect	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of data virtualization.	incorrect	
MC	Which statement is NOT 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	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
