Hello guys, I really need help. Actually, I don't have basic knowledge about database serve but the things is I have to create ERD table database(mysql) into my project(courier national) which is customer when login can view his or her order,clerk may only add,edit,delete customer and manager same things like a clerk. During login, we have to check database either match with the user input such as password and username. I have already created GUI but I don't know how to connect with the database. Why we should need database serve instead of only database.
I also attach my gui and what the first step must do?
