# MariaDB setup This directory hosts any new SQL table added to genenetwork3. When preparing statements, be sure to follow [this](https://www.sqlstyle.guide/) style guide. Also, not that in some tables, we use the json data format; therefore make sure you have MariaDB version 10.2 and later which include a range of JSON supporting functions. Read about that [here](https://mariadb.com/resources/blog/json-with-mariadb-10-2/)
