  Explanation/Reference:

  In Tableau, a story is a sequence of visualizations that work together to convey information. You can create stories to tell a data narrative, provide context, demonstrate how decisions relate to outcomes, or to simply make a compelling case.

  A story is a sheet, so the methods you use to create, name, and manage worksheets and dashboards also apply to stories (for more details, see Workbooks and Sheets). At the same time, a story is also a collection of sheets, arranged in a

  sequence. Each individual sheet (worksheet or dashboard) in a story is called a story point.

  When you share a story--for example, by publishing a workbook to Tableau Public, Tableau Server, or Tableau Online--users can interact with the story to reveal new findings or ask new questions of the data.

• Question 193:

  In which of the following scenarios would having a live connection be more beneficial than using an extract?

  A. Analyzing real time stock prices
  B. Analyzing real time data from production systems
  C. Analyzing historical housing prices
  D. Analyzing and tracking real time flight updates
  E. Analyzing a subset of a dataset having 1 billion rows
  A. Analyzing real time stock prices
  B. Analyzing real time data from production systems
  D. Analyzing and tracking real time flight updates

  ---

  Explanation/Reference:

  Extracts would be more beneficial for analyzing historical prices where we won't be making use of any real time data being streamed. Same is the case for enormous datasets having billions of rows (extracts will be more efficient in analyzing subsets of such large data).

  As for live stock prices, flight updates, real time updates from production or mission critical systems-having a live connection is the most logical choice, since we need access to the most fresh and recent data possible at all times!
