How to Explore Data In Progress Overview

Having a lot of data in your database is great, knowing how to get value out of it can be challenging. The first step is to explore what data you have. We want to show how to get oriented to a dataset and then how to explore it systematically. Show how to use SQL and simple visualizations to start finding insights in the data.
