Access databases can be shared. The preferred method is to split the
application into two databases. One database, called the back end, will
contain ONLY tables. The other database, called the front end, will contain
all other objects plus links to the tables in the back end. The back end
database is placed on a network share and the front end is distributed to
each user although it is possible to share the front end also. It just
makes for a less stable setup.
