Excellent! That was the very last exercise in the entire course – congratulations!

You've just completed the second course in the Creating Database Structure track. You've learned what data types are available when creating SQL tables. You've also learned how to work with identities and sequences and how to modify existing columns.

The next course in the track will show you how to add constraints to your tables. This way, your users will only be able to insert certain values into table columns. See you there!
