This document provides a tutorial on using migrations and Artisan commands in Laravel to manage databases. It demonstrates creating a migration to generate a database table, adding data to the table using another migration, and using Artisan commands like migrate, migrate:rollback and migrate:reset to run and undo the migrations. The migrations handle both creating/modifying the table schema and inserting/deleting sample data from the table. Artisan is the CLI for Laravel that provides commands to interact with migrations and manage the database structure.

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.
