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	Data virtualization isolates applications and users from the actual (combinations of) data integration patterns used.	incorrect	Data virtualization extensively uses data consolidation techniques such as ETL.	correct	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	Enterprise Information Integration (EII) is an example of...	data replication.	incorrect	data consolidation.	incorrect	data propagation.	incorrect	data integration.	correct	
MC	Which statement is NOT CORRECT?	The operational usage of business intelligence aims for a low (or even zero) latency so interesting events or trends in the data can be immediately detected and accompanied with the appropriate response.	incorrect	Analytics techniques are more and more used at the operational level as well by front-line employees.	incorrect	Analytics for tactic/strategic decision making increasingly uses real-time operational data combined with the aggregated and historical data found in more traditional data warehouses.	incorrect	Nowadays, we see a complete divergence of the operational and tactical/strategic data needs and of the corresponding data integration tooling.	correct	
MC	Which statement is CORRECT?	An important disadvantage of the consolidation approach is that it does not cater for historical data.	incorrect	The focus of MDM is on unifying company-wide reference data types such as customers and products.	correct	Enterprise Information Integration (EII) is an example of data propagation.	incorrect	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of data federation.	incorrect	
MC	The choreography pattern to manage sequence and data dependencies is a...	decentralized approach.	correct	centralized approach.	incorrect	
MC	The federation pattern typically follows...	a pull approach	correct	a push approach	incorrect	
MC	Which statement is 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	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
