Data in databases is typically spread across many tables, but that's not helpful for analyses. In this session you'll learn how to join data from different tables together to get it into a state for analysis. You'll also learn to analyze and visualize retail data through a dataset on book sales from a bookstore.

In this session we use DataLab. All you need is a DataCamp account. Note that members of some enterprise groups do not yet have access to use DataLab. Create a free DataCamp account with your personal email address to follow along.

We recommend that you have taken the following course before watching:
