Professional Database Development Part IV
In most up-to-date offices, Access database users are working on a number
of different computer systems, but their computers are connected in
a local area network (LAN). Because of the network users can share a
single copy of an Access .mdb file located on a file server. In this kind of
setup, problems arising from out-of-date data and simultaneous changing of
data by multiple users are rare. As long as the appropriate locking scheme
has been implemented by the developer and all users are trained in what to
do in the event of locked records, little can go wrong.
However, the situation is not so simple in companies where some people
need to run Access applications on portable computers, or in company
offices so geographically distributed that it??™s impossible to link all copies of
an Access database with a LAN. In these situations, synchronizing the data
managed by the ???roving??? Access applications with the ???stationary??? copies in
the main office can be a daunting task.
