How to import and export big database files

Hello friends,
today i want to share some basic concepts but we need to know about import and export databases. If it is small database file, we can directly export or import from the phpmyadmin.
Process to export:
1) Go to phpmyadmin -> click on database -> there we have button called “export”.
2) When we click on that button, we got a screen like in which format do want to export from database ( Like .sql,.txt,.zip,.zar or just open it that browser) 3) When we click on “Go” button, we will get database backup file.
Process to import:
1) We have the database, but we want to import database to that existing database.
2) Click on “import” button and then we have the separate screen click on browse and select the database file and click on “Go” button, it will successfully import the database.
