SQL tables and their relationships/indexes/keys are part of the business logic - so you definitely have business rules on SQL. But, there is a certain level of what to put on SQL and what to save for your code...
Triggers are very powerful to do other things while something happened to one of your tables, but it has a performance penalty. I saw databases where an insert that should take of a fraction of a millisecond took over 2 seconds because of the complex computations and data changes from within a trigger. Also if you got into the trigger things you can easily get a situation where trigger fires trigger that fires trigger...and so on. A very unpleasant situation to deal with when errors occur...
So do not use triggers if you can avoid, try to create stored procedures for complex insert/update scenarios!
I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)
