MC	Which statement is NOT 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typically induces a certain measure of latency, so the timeliness dimension may suffer, with the data being slightly out of date.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	An important disadvantage of the consolidation approach is that it does not cater for historical data.	correct	
MC	Which statement is NOT CORRECT?	Process execution languages such as WS-BPEL aim at managing both the control and data flow.	incorrect	Enterprise Information Integration (EII) is an example of data integration.	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	Process execution languages such as WS-BPEL aim at managing only the control flow.	correct	
MC	Which statement is NOT CORRECT?	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	The control flow perspective of a business process specifies the correct sequencing of tasks (e.g., a loan offer can only be made when the credit score has been calculated). 	incorrect	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.	correct	Process integration is to integrate and harmonize the various business processes in an organization as much as possible.	incorrect	
MC	Which statement is NOT CORRECT?	Data virtualization isolates applications and users from the actual (combinations of) data integration patterns used.	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	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	The choreography pattern to manage sequence and data dependencies is a...	centralized approach.	incorrect	decentralized approach.	correct

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	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	SQL is well suited to query structured collections of records as well as unstructured data such as text.	incorrect
