MC	Which statement is NOT CORRECT?	An important disadvantage of the consolidation approach is that it does not cater for historical data.	correct	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typically induces a certain measure of latency, so the timeliness dimension may suffer, with the data being slightly out of date.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	Besides the traditional set-up with ETL and a data warehouse, data lakes can also be considered an implementation of the consolidation pattern. 	incorrect	
MC	Which statement is CORRECT?	Enterprise Information Integration (EII) is an example of data replication.	incorrect	The choreography pattern to manage sequence and data dependencies is a centralized approach.	incorrect	Nowadays, we see a complete divergence of the operational and tactical/strategic data needs and of the corresponding data integration tooling.	incorrect	Enterprise Information Integration (EII) is an example of data integration.	correct	
MC	Which statement is CORRECT?	Enterprise Information Integration (EII) is an example of data consolidation.	incorrect	The choreography pattern to manage sequence and data dependencies is a decentralized approach.	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	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of data consolidation.	incorrect	
MC	The federation pattern typically follows...	a pull approach	correct	a push approach	incorrect	
MC	Which statement is CORRECT?	The prevalent approach for indexing full text documents is an inverted index.	correct	It makes no sense to look at HTML markup when calculating the weight of a term to a page for web search. 	incorrect	SQL is well suited to query structured collections of records as well as unstructured data such as text.	incorrect	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
