Is Tableau A OLAP tool?

In the end, Tableau works amazingly well on relational databases, and while it does connect to OLAP cubes, doing so is duplicative of the aggregation and hierarchy capabilities native to Tableau. And Tableau is even optimized for many non-SQL and big data solutions, such as the direct connector to Google’s BigQuery.

How is the multidimensional data model used in OLAP?

The databases that are configured for OLAP use multidimensional data model, enabling complex analysis and ad hoc queries at a rapid rate. The multidimensional data model is analogous to relational database model with a variation of having multidimensional structures for data organization and expressing relationships between the data.
