title: Creating registration form using Java and connect it with online database
body: <p>I am required to create a JAVA project to implement a system where user can register and login through it and make a reservation for a restaurant. This JAVA program must be able to run on any computer. So what can I do to implement this system? Do I need MySQL or SQLite or anything?</p>
  <p>I had tried to use Google MySQL cloud, I already create the GUI and it only works for my PC but not others. What system should I use to store the data user?
