Module 1 Product and Overview

The aim of this first short section is to ensure learners know about the products in the Tableau ecosystem, what the installation/ update process looks like and will run through a typical end-to-end publishing journey for Tableau from .tds to Tableau online and end users.

Module 4 Visualizing and Interactivity

This module is about designing visuals to find insights in the data, combining measures in charts and tables, leveraging parameters, tooltips, dashboard objects, filters and table calculations to create great interactive visualisations and dashboards.

Module 5 Enhancements
