Databases are commonly used as a simple file that contains specific information about the keeper. A database can and are used in almost every corporation or business, no matter how small or big it is.
It is quite simple to create a database that contains information like students name, surname and some grades, but it gets more complex when we add some specific information like who inserted some specific grade in some specific subject, it even gets harder when we start creating functions and adding indexes. This is the point when a smart student or paid employee comes in and handles it.
Creating functions and adding indexes or even creating a table using PostgreSQL is not that simple. To login into PostgreSQL, the user has to create a database in cmd folder, then open sqlShell and login into the database using login and password.
