And the query optimizer is aware of the relationship of course, and queries on the main table can be optionally routed to the mat-view. (see http://docs.oracle.com/cd/E11882_01/server.112/e25554/qradv.htm) And if you're willing to have a slight delay for the updating of the mat-view (async mode), you don't slow down inserts on the main table, and background processes (or threads on windows) "mine" the undo/redo logs to update the mat-view. In sync mode, you don't write the trigger, that's done for you, you just define the view as usual. But I'm no expert on the subject, just sharing perspective from the non-lite point of view, that's all. See http://docs.oracle.com/cd/E16338_01/server.112/e10706/repmview.htm for details. Here it's "Enable Data Subsetting" I guess.
