Migration & Artisan

Artisan :- Artisan is the name of the command-line interface included with Laravel. It provides a number of helpful commands.

To view all available Artisan commends type “<project_dir>/ php artisan list “

on your command line.

Migration :- Migrations are a type of version control for your database.

It allows me to create my tables easily, without writing a single line of database language for example :- mysql etc.

Before install migration in your project you need to be configure your database file.
