In this course you will learn more about the historical design of databases and the use of SQL in the PostgreSQL environment. Using SQL techniques and common commands (INSERT INTO, WHERE, ORDER BY, ON DELETE CASCADE, etc) will enable you to create tables, column types and define the schema of your data in PostgreSQL. You will learn about data modeling and how to represent one-to-many and many-to-many relationships in PostgreSQL. Students will do hands-on assignments creating tables, inserting data, designing data models, creating relational structures and inserting and querying relational data in tables.

Dr. Chuck delivers once again. To me there couldn't be any better explanation for SQL than this. I used to suck at SQL during university as well but after this course, I love SQL!

I am already familliar with PostgreSQL so it was great to review the basics. Its a great course for that.

Lectures are decently produced and informative. However, since this is a basic course, most people need way more extensive SQL practice than the trivial assignments provided by this course.
