Oracle has "basic" replication and "advanced" replication. The basic allows read-only copies of data whilst advanced can give multiple updaters at different locations and can get as complicated as you like.

IMHO, the key to a good replication environment is in the planning. Determining up front whether conflicts will occur (when the data is resync'd back in to the central store) and possibly architecting parts of the database to avoid some/all conflicts is key.

If you're new to replication, using the gui replication manager is a good way to get up and running relatively quickly, but I'd advise having a good study of the replication manuals to see all the possibile issues that need to be considered.

Oracle were touting an architecture called "Oracle-to-go" or "Web-to-go" some time ago which (claimed) to simplify all of this - but I've heard nothing recently.
