bidirectional replication possible ?

Is bidirectional replication possible in oracle ? I'm familiar only with MS SQL replication method - one tabel can be replicated in only one direction "and should be regarded as read-only at the destination place"

If oracle has another methods that allow to replicate both ways please point me to source where I can read about this !

Thanks for reading this.
Alexey.
