MC	The federation pattern typically follows...	a push approach	incorrect	a pull approach	correct	
MC	Which statement is NOT CORRECT?	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	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typically induces a certain measure of latency, so the timeliness dimension may suffer, with the data being slightly out of date.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	
MC	Which statement is NOT CORRECT?	The choreography pattern to manage sequence and data dependencies is a decentralized approach.	incorrect	Data virtualization extensively uses data consolidation techniques such as ETL.	correct	The focus of MDM is on unifying company-wide reference data types such as customers and products.	incorrect	The data flow perspective of a business process focusses on the inputs of the tasks (e.g., the interest rate offered depends on the credit score). 	incorrect	
MC	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of...	data propagation.	correct	data virtualization.	incorrect	data federation.	incorrect	data consolidation.	incorrect	
MC	Ideally, data integration should include...	only processes.	incorrect	only data.	incorrect	both processes and data.	correct	
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typically induces a certain measure of latency, so the timeliness dimension may suffer, with the data being slightly out of date.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	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of data virtualization.	correct	Enterprise Information Integration (EII) is an example of data integration.	incorrect	Process execution languages such as WS-BPEL aim at managing both the control and data flow.	incorrect	
MC	Which statement is CORRECT?	It makes no sense to look at HTML markup when calculating the weight of a term to a page for web search. 	incorrect	The prevalent approach for indexing full text documents is an inverted index.	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	SQL is well suited to query structured collections of records as well as unstructured data such as text.	incorrect
