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	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	
MC	Which statement is NOT CORRECT?	Enterprise Information Integration (EII) is an example of data integration.	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	Enterprise Information Integration (EII) is an example of data propagation.	correct	Ideally, data integration should include both processes and data.	incorrect	
MC	Which statement is NOT CORRECT?	Process integration is to integrate and harmonize the various business processes in an organization as much as possible.	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	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	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	
MC	The choreography pattern to manage sequence and data dependencies is a...	decentralized approach.	correct	centralized 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	
MC	Which statement is NOT CORRECT?	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	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	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	Ideally, data integration should include...	only data.	incorrect	both processes and data.	correct	only processes.	incorrect	
MC	Which statement is NOT CORRECT?	The prevalent approach for indexing full text documents is an inverted index.	incorrect	Master Data Management (MDM) compromises a series of processes, policies, standards, and tools to help organizations to define and provide multiple points of reference for all data that is "mastered". 	correct	The federation pattern typically follows a pull approach.	incorrect	A key element in MDM is a centrally governed data model and metadata repository.	incorrect
