MC	Ideally, data integration should include...	only processes.	incorrect	both processes and data.	correct	only data.	incorrect	
MC	Enterprise Information Integration (EII) is an example of...	data integration.	correct	data consolidation.	incorrect	data replication.	incorrect	data propagation.	incorrect	
MC	Which statement is CORRECT?	Setting up an MDM initiative involves a large number of steps and tools, including data source identification, mapping out the systems architecture, constructing data transformation, cleansing and normalization rules, providing data storage capabilities, monitoring and governance facilities, and so on. 	correct	Process execution languages such as WS-BPEL aim at managing only the control 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	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...	both the control and data flow.	correct	only the control flow.	incorrect	only the data flow.	incorrect	
MC	Which statement is CORRECT?	Enterprise search technologies are strongly related to standard web search products and providers (e.g., Google), but aim to offer a series of tools which can be deployed and used externally such that an organization can expose itself to the outside world.	incorrect	The prevalent approach for indexing full text documents is an inverted index.	correct	SQL is well suited to query structured collections of records as well as unstructured data such as text.	incorrect	It makes no sense to look at HTML markup when calculating the weight of a term to a page for web search. 	incorrect	
MC	Which statement is NOT 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	Data virtualization extensively uses data consolidation techniques such as ETL.	correct	
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	
MC	The choreography pattern to manage sequence and data dependencies is a...	centralized approach.	incorrect	decentralized approach.	correct	
MC	Which statement is CORRECT?	Data virtualization extensively uses data consolidation techniques such as ETL.	incorrect	The federation pattern typically follows a push approach.	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 both the control and data flow.	correct
