What programming languages Tableau use?
Tableau uses a special language called VizQL (Visual Query Language) to translate user activity into data queries and visualisations. It also works with SQL, MDX, and DAX to connect to different databases and handle OLAP data. Users can set up their own calculations using a formula language similar to SQL. Under the hood, Tableau is built mainly with C++ and Java. It also provides APIs in Python, R, and JavaScript to extend features and integrations, and to automate tasks.
