# Part 5 - Database

PREREQUISITES

• Finished Laravel exercise -> Part 4 - Automation
• Finished Laravel -> Database migrations
• Finished Laravel -> Eloquent models

REMARKS

• The many side of the relationship always holds the foreign key
  • A programme can have multiple students subscribed -> programme_id is defined in students table
• A student can enroll in multiple courses AND a course can be followed by multiple students. This is a many-to-many relationship which we have to implement by using an associative table student_courses.
  • If you use the command php artisan make:model StudentCourse -m, the corresponding database table will be named student_courses. According to the naming conventions, we also advice to use studentcourses() as the associated Eloquent hasMany relationship method.
