I've got 30 or so users running against a read-only Access database with no
problems, however, if several (meaning 2 or more) open it for update, they
have problems with lock conflicts because it seems to use a disk sector
locking algorithm. There is also little in the way of security. It's an all
or nothing proposition. Nothing at even at the table level. It doesn't do
triggers either, although it does handle constraints fairly well. I can't
comment on what happens if you have a large table. You do need to compress
the database regularly. I've had trouble with databases becoming corrupt
while doing automated compress operations. SQL Anywhere is a lot better for
not much more money.
