We hope the lessons have given you a bit more experience with SQL and a bit more confidence to use SQL with your own data.
We've just brushed the surface of what SQL is capable of, so to get a better idea of how SQL can be used in the real world, we'll be adding more articles in the More Topics part of the site. If you have the time, we recommend that you continue to dive deeper into SQL!
If you need further details, it's also recommended that you read the documentation for the specific database that you are using, especially since each database has its own set of features and optimizations.
If you have any suggestions on how to make the site better, you can get in touch using one of the links in the footer below.
