MC	Which statement is NOT CORRECT?	Analytics techniques are more and more used at the operational level as well by front-line employees.	incorrect	Nowadays, we see a complete divergence of the operational and tactical/strategic data needs and of the corresponding data integration tooling.	correct	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	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	
MC	Enterprise Information Integration (EII) is an example of...	data consolidation.	incorrect	data integration.	correct	data propagation.	incorrect	data replication.	incorrect	
MC	Which statement is CORRECT?	Enterprise Information Integration (EII) is an example of data consolidation.	incorrect	Enterprise Information Integration (EII) is an example of data propagation.	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	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 replication.	incorrect	Data virtualization isolates applications and users from the actual (combinations of) data integration patterns used.	correct	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of data virtualization.	incorrect	Process execution languages such as WS-BPEL aim at managing only the data flow.	incorrect	
MC	Process execution languages such as WS-BPEL aim at managing...	both the control and data flow.	correct	only the control flow.	incorrect	only the data flow.	incorrect	
MC	Which statement is NOT CORRECT?	Analytics techniques are more and more used at the operational level as well by front-line employees.	incorrect	The prevalent approach for indexing full text documents is an inverted index.	incorrect	Enterprise Information Integration (EII) is an example of data replication.	correct	Process execution languages such as WS-BPEL aim at managing both the control and data flow.	incorrect	
MC	Which statement is CORRECT?	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	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	
MC	Ideally, data integration should include...	only processes.	incorrect	both processes and data.	correct	only data.	incorrect	
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	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	
MC	Which statement is NOT CORRECT?	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	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
