Which statement accurately describes aliases?

Question

Options

• AYou can assign an alias to a field member before creating a visualization.
• BWhen you assign an alias, the name changes in the database.
• CYou can create an alias for a discrete measure.
• DYou can create an alias for a continuous dimension.

• A
  91% (52)
• B
  2% (1)
• C
  5% (3)
• D
  2% (1)

Explanation

Option A is correct because aliases are display-name substitutions you can assign to dimension members at any time - including before you place a field on a view - giving you flexibility in how labels appear without touching the visualization first.

Why the distractors are wrong:

• B is false: aliases only change the displayed label in the tool (e.g., Tableau); the underlying database value is never altered.
• C is false: aliases apply to dimension members, not measures - you cannot alias a measure regardless of whether it is discrete or continuous.
• D is false: aliases only work on discrete dimensions (shown in blue); continuous dimensions are numeric axes and don't have individual members to rename.

Memory tip: Think of aliases as "nickname stickers" - you stick them on individual discrete dimension members (like renaming "US" to "United States"), they don't touch the database, and you can put the sticker on before the item is even displayed on screen.
