Re: Pre-DML trigger vs Foreign keys
Anushka,
A MySQL database is a particular kind of data store, a relational database; as such, business rules are integral to it . There's a huge, coherent and very helpful body of database theory & practice for implementing biz rules in the database layer.
Whether you implement biz rules (or which ones you implement) in the app or DB layer depends mostly on the architecture of you app and on whether the RDBMS you are using is a full & robust enough implementation of SQL to do the job well.
