Laravel includes the ability to seed your database with data using seed classes. All seed classes are stored in the database/seeders directory. By default, a DatabaseSeeder class is defined for you. From this class, you may use the call method to run other seed classes, allowing you to control the seeding order.

What are Relationships?

Database tables are often related to one another. For example, a blog post may have many comments or an order could be related to the user who placed it. Eloquent makes managing and working with these relationships easy, and supports a variety of common relationships:

• One To One
• One To Many
• Many To Many
• Has One Through
• Has Many Through
• One To One (Polymorphic)
• One To Many (Polymorphic)
• Many To Many (Polymorphic)
