Answer 1

You could use triggers to do the job but....
I am afraid that you will spend an enormous amount of time making sure that everything works. A single database with some partitioned tables may be better. Do you actually need multiple databases or just one database with multiple filegroups spread over physical devices? You may consider that option too. Matej
