It's my first time to use triggers so....?

To really do it right, create a test database and some tables to practice writting triggers on so you can actually see what they do.
Triggers can be quite the tripping point in code and if you don't have a very firm grasp on what they actually do and how they work and how to use them, you're going to make some really huge and embarassing mistakes.
