MC	Which statement is NOT 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typically induces a certain measure of latency, so the timeliness dimension may suffer, with the data being slightly out of date.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	An important disadvantage of the consolidation approach is that it does not cater for historical data.	correct	
MC	The federation pattern typically follows...	a push approach	incorrect	a pull approach	correct	
MC	The federation pattern typically follows...	a push approach	incorrect	a pull approach	correct	
MC	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of...	data consolidation.	incorrect	data propagation.	correct	data virtualization.	incorrect	data federation.	incorrect	
MC	Which statement is CORRECT?	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.	correct	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of data federation.	incorrect	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of data consolidation.	incorrect	Data virtualization extensively uses data consolidation techniques such as ETL.	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	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	Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of data virtualization.	correct	Process integration is to integrate and harmonize the various business processes in an organization as much as possible.	incorrect	The choreography pattern to manage sequence and data dependencies is a decentralized approach.	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	Process integration is to integrate and harmonize the various business processes in an organization as much as possible.	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	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	
MC	The federation pattern typically follows...	a pull approach	correct	a push approach	incorrect	
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	The federation pattern typically follows a push approach.	correct	The prevalent approach for indexing full text documents is an inverted index.	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
