What is Tableau used for?
The question is about Tableau
Answer:
Tableau uses principally VizQL (Visual Query Language) to translate user actions into data queries and visualizations. It supports SQL for database querying, as well as MDX and DAX for OLAP data. Advanced data manipulations can be done in Tableau using the formula language inside its custom calculation fields, syntactically similar to SQL functions. Core development of Tableau itself is done in C++ and Java, but Tableau provides APIs in Python, R, and JavaScript for extended functionality, automation, and integration with other tools.
