Instruction

That's it! You've just finished the last exercise in the entire course. Congratulations!

In this course, you've learned about various constraint types:

  1. PRIMARY KEYs and FOREIGN KEYs
  2. UNIQUE
  3. NOT NULL
  4. CHECK
  5. DEFAULT

You are now able to define tables in a way that will help you maintain data integrity and correctness.

In the next course in the track, we'll talk about views – a concept we've not mentioned so far. See you there!
