AWS

Amazon Athena make it easy to analyze semi-structured and non-structured data like json, xml etc. directly in Amazon S3 using SQL. However, it also allows you to easily query a number of relational databases hosted in AWS such as mySQL and PostgreSQL. For any Data Scientist, this opens up a world of potential because now it’s possible to write SQL queries that combine data from both relational and non-relational data source in a single query!
