Laravel Eloquent Relationships

When working with databases in Laravel, Eloquent ORM (Object Relational Mapping) makes it easy to define relationships between models. Whether you're building a blog, a CRM, or an eCommerce platform, mastering relationships like one-to-one, one-to-many, and many-to-many is essential for clean, efficient code.

1. One-to-One Relationship

A one-to-one relationship in Laravel is a basic database relationship where a record in one table is associated with exactly one record in another table, and vice versa.

2. One-to-Many Relationship

A one-to-many relationship defines a relationship where a single model (the "parent") can have multiple related models (the "children"), while each child belongs to only one parent. This is one of the most common database relationships.

3.Many-to-Many Relationship

A many-to-many relationship is more complex than one-to-one or one-to-many relationships. It occurs when multiple records in one table are associated with multiple records in another table. This requires a pivot table (junction table) to facilitate the relationship.
