MC	Ideally, data integration should include...	only processes.	incorrect	only data.	incorrect	both processes and data.	correct	
MC	Which statement is 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	SQL is well suited to query structured collections of records as well as unstructured data such as text.	incorrect	Data virtualization isolates applications and users from the actual (combinations of) data integration patterns used.	correct	The federation pattern typically follows a push approach.	incorrect

MC	Which statement is NOT 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	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 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	
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	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typically induces a certain measure of latency, so the timeliness dimension may suffer, with the data being slightly out of date.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
