Databases are extraordinarily powerful in managing sets of data. This lab is aimed at students with a moderate understanding of data engineering, and Python who want to understand how to perform aggregates on data such as COUNT(), SUM(), and AVG(). We will also look into advanced statements like CASE, and functions like DATEDIFF() and CONCAT(). We will walk through the changing requirements of a bug-tracking application and how to handle them.
Learning Objectives
Upon completion of this lab you will be able to:
- Utilize SQL aggregate functions
- Utilize complex functions
- Learn how to get complex insights from your data
Intended Audience
This lab is intended for:
- Data engineers
- Anyone interested in gaining insights from data using SQL
Prerequisites
You should possess:
- A moderate understanding of Python
- A basic understanding of data engineering concepts
Lab Environment
Due to the resources being provisioned for this lab, it can take up to 20 minutes from when you start the lab until the SQL instance becomes ready.
