**Quick Start:** [Run an example

on your local machine or [study some
examples](https://github.com/apache/carbondata/tree/master/examples/spark2/src/main/scala/org/apache/carbondata/examples).
-**CarbonData SQL Language Reference:** CarbonData extends the Spark SQL
language and adds several [DDL](./ddl-of-carbondata.md) and
[DML](./dml-of-carbondata.md) statements to support operations on it.Refer to

**Programming Guides:** You can read our guides about [Java APIs
supported](./sdk-guide.md) or [C++ APIs supported](./csdk-guide.md) to learn
how to integrate CarbonData with your applications.
## Integration
-CarbonData can be integrated with popular Execution engines like
[Spark](./quick-start-guide.md#spark) , [Presto](./quick-start-guide.md#presto)
and [Hive](./quick-start-guide.md#hive).Refer to the [Installation and
Configuration](./quick-start-guide.md#integration) section to understand all
modes of Integrating CarbonData.

I think it's not proper to mention Alluxio after e(*Not E*)xecution engines
like SparkSQL/Presto/Hive.
Meanwhile we can add another paragraph and mention CarbonData can integrate
with other storage engines such as HDFS, S3, OBS, Alluxio.
@chenliang613 How do you think about it?
