When learning SQL, you first need a database. In this video, we help you make your choice. There are many free, open-source options: MySQL, PostgreSQL, MariaDB, Sqlite, and many others. You can also choose an established commercial option like Oracle, SQL Server, or DB2. Better still, you can run the database on your own server or in the cloud!
Stay tuned! We'll be adding additional learning resources very soon.
