Hi:
I am really new to database area. And got this maybe really stupid question.
1. If I got some large multimedia files (MP3, DivX films), does DBMS
store those files in to the database table or just make a link to where
it was? If DBMS only make a link to those files, once I delete one, the
database may crash, isn't it? If it store in tables or somewhere in
database, how do you set it?

2. Once I create some tables in database, does DBMS store those thing in
a single file on my hard driver some where? If it's not, how can I
backup it?
3. Base on question 2, if DBMS can store database as single file on my
HD, can other DBMS to access it operate with it? E.g. I am trying MySQL
and found PostgreSQL do better job, can I just setup PostgreSQL and read
the file made by MySQL and start everything again?
Many thanks
