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typically induces a certain measure of latency, so the timeliness dimension may suffer, with the data being slightly out of date.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	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	An important disadvantage of the consolidation approach is that it does not cater for historical data.	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	Which statement is NOT CORRECT?	Data virtualization extensively uses data consolidation techniques such as ETL.	correct	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	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?	Process integration is to integrate and harmonize the various business processes in an organization as much as possible.	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	Ideally, data integration should include both processes and data.	incorrect	Process execution languages such as WS-BPEL aim at managing only the control flow.	correct
