Hi @Luiz Henrique Carvalho Martarelli 

You can take a look at this post: Trigger or Callback?

And for more detail information: Using Triggers 

If you have interested, the Developer Community has a Discord with a dedicated Channel for Portuguese Speakers. laugh

Best Regards,

Unless things have changed with IRIS I generally prefer to use triggers over any of the object implementations.  Properly defined triggers will be executed whether you are doing an object Save or a SQL INSERT/UPDATE/DELETE.  You may only want to perform the code during object save but I find why not implement the code in a trigger where you know it will always be executed.  Additionally triggers provider  



syntax which is valuable.
