You probably could, but it would be overkill for a single user
environment, and painfully small for multiuser.

Ugly. You throw away many of the advantages of a separate database
server (multiuser access, primarily) and end up with an embedded
database that was never intended to be an embedded database - and that
after a lot of work and a lot of bugs.

Look at <> if you need SQL or
<>, <>, or
possibly <>.

Check the licensing terms before investigating too far - while some of
them are freely available, some appear freely available at first glance
but have very high licensing costs for commercial use. discusses a bunch of SQL
databases, including embedded ones.
discusses some non-SQL embedded DBs.
