+<p class="content-p">
+If you want to do multi-dimension analysis on large data sets (billion+ rows) with low query latency (sub-seconds), Kylin is a good option. Kylin also provides good integration with existing BI tools (e.g Tableau).

+
+<p class="content-header">Why existing SQL-on-Hadoop solutions fall short?</p>
+<p class="content-p">

+
+<p class="content-header">What is MOLAP/ROLAP?</p>
+<p class="content-p">
+MOLAP (Multi-dimensional OLAP) is to pre-compute data along different dimensions of interest and store resultant values in the cube. MOLAP is much faster but is inflexible.
+ROLAP (Relational-OLAP) is to use star or snow-flake schema to do runtime aggregation. ROLAP is flexible but much slower.
+</p>
+<hr/>
+
+<p class="content-header">How does Kylin support ROLAP/MOLAP?</p>
+<p class="content-p">
+Kylin builds data cube (MOLAP) from hive table (ROLAP) according to the metadata definition.
+If the query can be fulfilled by data cube, Kylin will route the query to data cube that is MOLAP.
+If the query can’t be fulfilled by data cube, Kylin will route the query to hive table that is ROLAP.
+Basically, you can think Kylin as HOLAP on top of MOLAP and ROLAP.
+</p>
+<hr/>
+<p class="content-header">What does a Kylin query look like?</p>
+<p class="content-p">
+Kylin supports join, projection, filter, aggregation, groups and sub-query. For example:
+<div align="left">
+

+</div>
+<hr/>
+
+<p class="content-header">What Hadoop components does it work with?</p>
+<p class="content-p">
+Kylin depends on HDFS, MapReduce, Hive and HBase.
+Hive and MapReduce is used for cube building. Hive is used for pre-join and MapReduce is used for pre-aggregation.
+HDFS is used to store intermediated files during cube building.
+HBase is used to store data cube and answer the query. HBase coprocessor is also used for query processing.
