This is a very old discussion and it comes up now and again in all
lists concerning database systems.

the entire document. It depends on your requirements!
Back to the original question:
> > How can I store these files in the BLOB field?Depending on how you want to normalize things, you could do with
a simple "files" table or with several tables that make sense to your
organization, eg: employee_cvs for example.
Next, I suggest you store something like a file extension (and the original
filename) and so on in order to be able to know what kind of document
is in the blob, as Firebird itself couldn't care less what's in it.
If you don't need referential integrity, it's often useful to store the
files in a separate database in order to speed up backup/restore
process of the main database, if something happens. With two-phase
commit, you can control transactions for both databases at the same
Have fun :-)
