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 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typically induces a certain measure of latency, so the timeliness dimension may suffer, with the data being slightly out of date.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

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	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	The prevalent approach for indexing full text documents is an inverted index.	correct	
MC	Which statement is NOT 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	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	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	
MC	Which statement is NOT CORRECT?	Process execution languages such as WS-BPEL aim at managing both the control and data flow.	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	The focus of MDM is on unifying company-wide reference data types such as customers and products.	incorrect	It makes no sense to look at HTML markup when calculating the weight of a term to a page for web search. 	correct
