I suspect that almost any sweeping statement that Oracle doesn't support some feature or other is wrong in the current day. Oracle can certainly handle columnar formatted data. The in-memory columnar format is just what it says, HCC provides columnar compression and Exadata has done columnar data access forever. I know little about Oracle specifically, but I do know that it is a huge beast with all kinds of feature that make generalization difficult.
