Multi-database system query with PrestoDB Server

Desciption of Presto DB Project

Hi everyone! Presto is an open source distributed SQL query engine for running interactive analytic queries against data sources of all sizes ranging from gigabytes to petabytes.
Our group use Presto DB 0.97 query engine to allow users run SQL queries according to metadata in MetaStore's database and allow user to save query results in indicated database.

1. In our web interface, we provide databases with their metadata(Database type, Database name......) from Metastore to help user write SQL queries.
2. Also, experienced users can run presto queries without knowledge of any metadata.
3. After executing the query, the user could save the returned result as a new datasource by clicking save.
