It is free and has InnoDB for foreign key constraints, triggers, custom functions, views, and many important things in the SQL world. It also has a large community, so you might find answers easier compared to Oracle and PostgreSQL. Review collected by and hosted on G2.com.

It does not have JSON data types, but it was included in version 5.7. I really dislike the fact that it does not have a real BOOLEAN data type, we need to use TINYINT and cast it in the application. Review collected by and hosted on G2.com.
