Jotish,

  Snapshots are of course proprietary but nothing prevents you from using the same mechanism as 'snapshot refresh' - having a log which holds the primary key and enough information to reconstruct the insert, update or delete statement, and triggers to fill it. It's exactly the way that the Sybase replication agent for Oracle works - the log is then processed by a replication server.
