MC	Which statement is CORRECT?	SQL is well suited to query structured collections of records as well as unstructured data such as text.	incorrect	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	
MC	Which statement is NOT 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	Analytics techniques are more and more used at the operational level as well by front-line employees.	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	Nowadays, we see a complete divergence of the operational and tactical/strategic data needs and of the corresponding data integration tooling.	correct	
MC	The federation pattern typically follows...	a push approach	incorrect	a pull approach	correct	
MC	Ideally, data integration should include...	only processes.	incorrect	only data.	incorrect	both processes and data.	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	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	An important disadvantage of the consolidation approach is that it does not cater for historical data.	correct	The choreography pattern to manage sequence and data dependencies is a decentralized approach.	incorrect	
MC	The federation pattern typically follows...	a pull approach	correct	a push approach	incorrect	
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typically induces a certain measure of latency, so the timeliness dimension may suffer, with the data being slightly out of date.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	An important disadvantage of the consolidation approach is that it does not cater for historical data.	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	
MC	Which statement is NOT CORRECT?	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	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
