Is it possible to convert a single user Access database to a multi-user
database? If so, how and what can be some of the major issues?
Access is multiuser by default. You have to go to a bit of effort to
make it single-user!
If the multiple users are on the same (fast, stable) local area
network, it's very strongly recommended that you split the database
into a "backend" containing the tables, and a "frontend" with all the
queries, forms, reports, code, etc. Each user will get a copy of the
frontend. See
http://www.granite.ab.ca/access/splitapp/ for a thorough
discussion and instructions. You *can* just put the database on a
shared drive, but doing so risks corruption, bad performance, and
bloating.
If the multiple users are at different sites, connecting over the
Internet, it's tougher! Access wasn't designed to be used over WAN
connections.
