wondering what URL, username, password are when you get connection with RDBMS? Where can i get them? I've read a lot of tutorials but they all just say something like "put that url and everything should be ok" without explanation
Jdbc-url is only special format of data that includes some information about your database that jdbc needs them for making connection to database (such as ip of your database, usernam and etc) You can easily google the jdbc-url that is compatible with your database type (mysql, oracle, postgres and etc)
