Syncronize data across databases

Hello Everyone,
I need to deploy a MS Access Database in 3 different geographical areas, the database will be identical in all three sites. Only one of the 3 will be the Master database where data entry will take place, the other two will simply be used for reporting. What would be the best way to create a data sync between the master and the other 2 databases without a human intervention? Say for example the database will synchronize every time data is changes to the Master.

Thanks

 I would have answered replication, but starting with A2007, it's been dropped from JET.  SQL Server still offers replication however.

 One question is; is it just new records that need to be synch'd up, or are you planning on deletes and edits as well.  If the latter, it really gets to be a chore.

Another thought; if users have internet connectivity at all times, you'd be far better to think about a remote access solution such as RDP/Citrix to handle this and forget about replication entirely.

I'm only concerned about new records, there will be no edits or deletions. What do you think it would be the best solution by keeping it in Access?

  That's simple enough then.  You can use a GUID for your primary keys so that every record is unique.  Then it's a simple merge into your "master" DB (that's basically how replication works).

  BTW, what version of Access are you planning to use?

If these 3 different geographical locations all are on the same network, you can just use linked tables. I never saw you mention the requirement for offline use.  If everyone is connected to the network couldn't you used linked tables?

  Not over a WAN with a JET DB.  You need very fat pipes and decent routers for it to work.
