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 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 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typically induces a certain measure of latency, so the timeliness dimension may suffer, with the data being slightly out of date.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? 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 Nowadays, we see a complete divergence of the operational and tactical/strategic data needs and of the corresponding data integration tooling. 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. incorrect Analytics techniques are more and more used at the operational level as well by front-line employees. incorrect MC Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of... data propagation. correct data federation. incorrect data consolidation. incorrect data virtualization. incorrect 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 virtualization. incorrect data propagation. correct data federation. incorrect data consolidation. incorrect MC Which statement is NOT 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 Enterprise Application Integration (EAI) and Enterprise Data Replication (EDR) are examples of data virtualization. correct The choreography pattern to manage sequence and data dependencies is a decentralized approach. incorrect 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 MC Ideally, data integration should include... only data. incorrect only processes. incorrect both processes and data. correct MC Which statement is NOT 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 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 It makes no sense to look at HTML markup when calculating the weight of a term to a page for web search. incorrect
