True
Traditional BI systems use a large volume of static data that has been extracted, cleansed, and loaded into a data warehouse to produce reports and analyses.
True
A(n) ________ is a major component of a Business Intelligence (BI) system that is often browser based and often presents a portal or dashboard.
User Interface
The Google search engine is an example of Big Data in that it has to search and index billions of ________ in fractions of a second for each search.
Web Pages
Online transaction processing (OLTP) systems handle a company's routine ongoing business. In contrast, a data warehouse is typically

close
________ cycle times are now extremely compressed, faster, and more informed across industries.
Business
The user interface of a BI system is often referred to as a(n) ________.
dashboard
A(n) ________ is a major component of a Business Intelligence (BI) system that holds source data.
data warehouse

end-user ad hoc reports, queries, and analysis
As the number of potential BI applications increases, the need to justify and prioritize them arises. This is not an easy task due to the large number of ________ benefits.
intangible
Software monitors referred to as ________ can be placed on a separate server in the network and use event- and process-based approaches to measure and monitor operational processes.
intelligent agents
Which of the following developments is NOT contributing to facilitating growth of decision support and analytics?
locally concentrated workforces
What type of analytics seeks to recognize what is going on as well as the likely forecast and make decisions to achieve the best performance possible?
prescriptive
Which of the following is NOT an example of transaction processing?
sales report
Big Data often involves a form of distributed storage and processing using Hadoop and MapReduce. One reason for this is
