No trial licenses necessary.
At least for those products I used to work with for years and decades.
Name of the company developing and selling those products: Oracle.
You could (and can) basically install and use all of their products (at least around the RDBMS thingy), with all named features.
No need to apply a license key.
And still they're making _some_ money with that type of business, don't they?
