Tableau
interactive business intelligence and visual data exploration
Why learn Tableau?
Useful for visual investigation and communicating metrics. Aggregation level, filters, and data freshness must remain clear to report consumers.
Where it came from
Tableau provides tools for connecting to data, exploring it visually, and sharing interactive analytics. It is a business intelligence platform rather than a database engine.
