After successive failures, I come here to ask for help in desperation.
All I need, is to be able to create and host locally a database, that I can later connect to via SQLDeveloper (preferably, but it can be any other program. That's what my professor recommended us using this year).
I've googled this prior to asking this question, but all I can find is tutorials on how to connect to the database. I first need to create one, in order to connect to it (or at least that's how I understood the concept).
Please give any suggestions, links to tutorials, programs that I need or questions regarding what i actually want all of this for.
