Hi,
Actually, I have a staff class. If user want to delete the particular staff record, I want to perform cascade delete for related table. Of course, we can use trigger, but if there are from different database or platform I may need to perform this operation when delete user record. Where should I place the code of cascade delete, business class, datasource class?

A member did tell me to have event class. However, I am not sure clear about it.

Thank you
