| Since Oracle did not have columnar store at the time, they compare the
"BLU

According

of

Reading the material at the link, and some follow-on stuff, it didn't look as if the IBM offering catered for OLTP data maintenance at the same time - which is what Oracle is claiming as their unique selling point.
