There are over 100 companies making different SQL. Sun Microsystems the company that made java made Mysql for free(Free to install, pay for support /some features) . Oracle bought sun so still have Mysql as a separate free database engine(which you will install on your pc and install a tool like SQL developer to connect to it). Oracle make most of their money selling "Oracle database" to enterprises. That database is designed for unrivalled uptime/partitioning/replication etc. Oracle live SQL classic is an easy way to learn Oracle SQL. In your browser you can start typing code now to learn. No need to create a database, just create some tables and you can fiddle with all of the options, but data inserted will probably be erased every day or similar. It is a playground. Oracle SQL developer is an Oracle program(and recently website) that can connect to an existing database. If you create an Oracle autonomous database on their cloud(free) you can use SQL developer to connect to it to run your commands. Your data will not be erased as it is a full database. You can also install it on your desktop to connect to many different databases(eg installed locally or in the cloud) Answer from WestEndOtter on reddit.com
