BigData / Tableau Interview Questions
What is Tableau Public?
Tableau Public is a free version of Tableau intended for publishing visualizations that anyone on the internet can view, rather than for private or internal business data.
- Workbooks are saved directly to Tableau's public cloud gallery, not to a private server.
- Every workbook published to Tableau Public is visible to anyone, and the underlying data can typically be downloaded by viewers — there is no way to keep it private.
- It's widely used by journalists, students, and hobbyist data analysts to showcase portfolio work, since it requires no licensing cost.
Because everything published is public, it should never be used for confidential, proprietary, or personally identifiable data. Organizations that need to share dashboards privately use Tableau Server or Tableau Cloud instead, which support authentication, permissions, and private hosting that Tableau Public simply does not offer.
