[freeCodeCamp] SQL Joins Tutorial: Cross Join, Full Outer Join, Inner Join, Left Join, and Right Join.

One of the most powerful and useful concepts in our relational database world is the join.

Joins allow us to re-associate our separated and normalized database tables.

Joins form the relationships between the entities in our apps by combining result sets from different tables into one result, or by allowing us to filter the result based on associated information.

I wrote a tutorial on joins on freeCodeCamp’s Developer News.

I hope you enjoy it and again thanks for reading!
