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 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 Analytics techniques are more and more used at the operational level as well by front-line employees. incorrect MC Enterprise Information Integration (EII) is an example of... data propagation. incorrect data integration. correct data replication. incorrect data consolidation. 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 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 isolates applications and users from the actual (combinations of) data integration patterns used. incorrect MC Which statement is NOT CORRECT? A key element in MDM is a centrally governed data model and metadata repository. 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 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 MC Which statement is NOT CORRECT?

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 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?

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 An ETL process typically induces a certain measure of latency, so the timeliness dimension may suffer, with the data being slightly out of date. correct 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 only the data flow. incorrect MC The federation pattern typically follows... a pull approach correct a push approach incorrect 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
