Hello The databases you mentioned are document databases (schema free) and not relational. In case you wish to use relational dbs such as Microsoft SQL Server or IBM DB2 the Express or Community versions are available with some restrictions for free. You can even use it for production purpose if the restrictions are acceptable to you. For example Microsoft SQL Server 2016 Express db size limit is 10GB. Google and you will know more. Hope it helps!
