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typically induces a certain measure of latency, so the timeliness dimension may suffer, with the data being slightly out of date.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 CORRECT?	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of data federation.	incorrect	Analytics techniques are more and more used at the operational level as well by front-line employees.	correct	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.	incorrect	Nowadays, we see a complete divergence of the operational and tactical/strategic data needs and of the corresponding data integration tooling.	incorrect	
MC	Which statement is 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). 	correct	Enterprise Information Integration (EII) is an example of data consolidation.	incorrect	Process execution languages such as WS-BPEL aim at managing only the control flow.	incorrect	Enterprise Information Integration (EII) is an example of data propagation.	incorrect	
MC	Which statement is CORRECT?	The prevalent approach for indexing full text documents is an inverted index.	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	
MC	Which statement is NOT CORRECT?	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	A key element in MDM is a centrally governed data model and metadata repository.	incorrect	The focus of MDM is on unifying company-wide reference data types such as customers and products.	incorrect	Setting up an MDM initiative involves a large number of steps and tools, including data source identification, mapping out the systems architecture, constructing data transformation, cleansing and normalization rules, providing data storage capabilities, monitoring and governance facilities, and so on. 	incorrect	
MC	Enterprise Information Integration (EII) is an example of...	data consolidation.	incorrect	data integration.	correct	data replication.	incorrect	data propagation.	incorrect	
MC	The choreography pattern to manage sequence and data dependencies is a...	decentralized approach.	correct	centralized approach.	incorrect	
MC	Which statement is CORRECT?	Nowadays, we see a complete divergence of the operational and tactical/strategic data needs and of the corresponding data integration tooling.	incorrect	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of data federation.	incorrect	Process execution languages such as WS-BPEL aim at managing both the control and data flow.	correct	Data virtualization extensively uses data consolidation techniques such as ETL.	incorrect	
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?	The focus of MDM is on unifying company-wide reference data types such as customers and products.	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	Setting up an MDM initiative involves a large number of steps and tools, including data source identification, mapping out the systems architecture, constructing data transformation, cleansing and normalization rules, providing data storage capabilities, monitoring and governance facilities, and so on. 	incorrect	A key element in MDM is a centrally governed data model and metadata repository.	incorrect
