Question

Which statement is correct?

Web Mining is a predictive analytic enabler.

OLAP is a predictive analytic enabler.

Big data only deals with relational data.

Business analytics always starts with data collection. Second and fourth.

Answer 1

A) False: Web mining is the application of data mining techniques to discover patterns from the World Wide Web. Both the procedures DM as well as predictive analytics deal with discovering secrets within big data. DM uses software to search for patterns, while predictive analytics uses those patterns to make predictions and direct decisions.

B) True: To organize and analyze business data, On-Line Analytical Processing (OLAP) uses a multidimensional approach . By storing data in highly optimized structures, businesses can very quickly explore the data and uncover important insights that would otherwise remain hidden. As a result, OLAP enables companies to achieve key organizational goals, including wide-ranging business intelligence and analytics. In short OLAP supports activities ranging from self-service reporting and analysis to purpose-built management applications such as planning and budgeting systems.

C) False: Big Data refers to very large and often complex data sets, so massive in size that they’re beyond the capability of managing with traditional software tools. The bulk of Big Data is composed of unstructured data types such as video, photos, audio, webpages, and multimedia content.

D) True: Business analytics starts with the data collection. However, not any data is collected. First, parameters for the collection of data are set so the data can be collected and collated accordingly.
