Register(new BranchingOperation()
.Add(Partial.Register(new FilterRecordsToAdd()).Register(new
OutputCommandOperation{CommandText="insert into ..."}))
.Add(Partial.Register(new FilterRecordsToUpdate()).Register(new
OutputCommandOperation{CommandText="update ..."}));
Where FilterRecordsToAdd/Update are your implementations of
AbstractOperation. OutputCommandOperation (or something like that) is the
built in operation to execute a write against the database.
