Hi Kiran, In HBase the data is denormalized but at the core HBase is KeyValue based database meant for lookups or queries that expect response in milliseconds. OLAP i.e. data warehouse usually involves heavy data crunching. HBase is not really intended for heavy data crunching. If you want to just store denoramlized data and do simple queries then HBase is good. For OLAP kind of stuff, you can make HBase work but IMO you will be better off using Hive for data warehousing.
