My old team needed some assistance with a problem that was happening in production. Rows from a database table were mysteriously disappearing when the users ran a certain application. The developers swore that their code did not delete these records.Since I trust nobody, I scanned the source code of all the database triggers in the system. Sure enough, there was a trigger on another table that deleted the records when a certain field got set to a value. Oh snap. This is just poor design. That's not what triggers are for.
There are two lessons to learn from this. One is to practice solid design and keep business rules out of the database triggers. The second is that the client server developers need to keep an eye on the code in the database triggers.
