Discover how to dissect the behavior of your customers using SQL queries on a PostgreSQL database. In this interactive online course, we use a sample dataset from an online store that sells groceries and other everyday items.

Customers are essential for every business. So, a lot of effort goes into understanding how they behave. Modern businesses need data analysis of the sales funnel and customer behavior. Both sales and marketing departments must understand what customers do by following their steps until they make a purchase.

In this interactive online course, you learn to analyze acquisition, conversion, and sales in PostgreSQL, while taking your SQL knowledge to the next level. Many of our users say the same thing happens with their business sales!

Through 72 interactive exercises, you learn how to prepare different customer behavior reports in PostgreSQL. You learn how to look at customer behavior and the entire customer journey, from the first visit to turning someone into a buyer, making sales, and keeping track of the customer's intent to leave.

You'll learn:

  • How to obtain the number of sign-ups for a specific time period using PostgreSQL and how to compare these numbers between different time periods.
