Project Overview All of the instructions are discussed in detail as you work through this lesson on your way to completing this project. Instructions Step 1: Get the Chinook database up and running. You can run the DB Browser database on your own machine (See the Set Up the DB Browser Database page) or you can use the provided workspace (see the Chinook Postgres SQL Workspace page). Step 2: Complete the SQL Question Sets This series of questions will confirm that you have mastered the main concepts taught throughout the SQL lessons. These questions will not be "graded" by a reviewer and are intended to help you self-assess. Step 3: Create the Presentation There isn't a 'right answer' for this portion of the project. The project is designed to allow you to be creative in the questions you ask and then write a SQL query to pull the data needed to answer your question successfully. You will use the pulled data to build a visual (bar chart, histogram, or another plot) that answers your question and present that information in a slide deck using PowerPoint, Google Slides or your favorite presentation software. See more information about what is required and how to submit the project on the Project Submission Details page.
