Hi,
Thank you for your reply.
When Column store indexes are created in an OLTP / OLAP tables, the tables will become read only. So in SQL  2012 version, this index was used for analysis services.
I heard someone said like column store indexes will store the pointers in Pages not like OLTP indexes.(tree map concept)
Any have I would like to get in depth knowledge of knowing the difference between row store and column store indexes.
Anymore responses will help !!!
