  Explanation/Reference:

  Data fields are made from the columns in your data source. Each field is automatically assigned a data type (such as integer, string, date), and a role: Discrete Dimension or Continuous Measure (more common), or Continuous Dimension or

  Discrete Measure (less common).

  Dimensions contain qualitative values (such as names, dates, or geographical data). You can use dimensions to categorize, segment, and reveal the details in your data. Dimensions affect the level of detail in the view.

  Measures contain numeric, quantitative values that you can measure. Measures can be aggregated. When you drag a measure into the view, Tableau applies an aggregation to that measure (by default).

  B. Ability to use the data offline
  D. Faster to work with

  ---

  Explanation/Reference:

  Extracts are advantageous for several reasons:

  1) Supports large data sets: You can create extracts that contain billions of rows of data.

  2) Fast to create: If you're working with large data sets, creating and working with extracts can be faster than working with the original data.

  3) Help improve performance: When you interact with views that use extract data sources, you generally experience better performance than when interacting with views based on connections to the original data.

  4) Support additional functionality: Extracts allow you to take advantage of Tableau functionality that's not available or supported by the original data, such as the ability to compute Count Distinct.

  5) Provide offline access to your data: Extracts allow you to save and work with the data locally when the original data is not available. For example, when you are traveling. To work with the MOST up-do-date data, use a live connection

  instead!
