Explain ORM in Laravel

ORM (Object-Relational Mapping) in Laravel is a technique used to convert data between incompatible type systems in object-oriented programming languages. In Laravel, the ORM system is provided by Eloquent, which is a powerful and elegant ActiveRecord implementation for working with your database.

1. Models

Models in Laravel represent the data structure of your application and are typically stored in the app/Models directory. Each Eloquent model corresponds to a database table. For example, a User model will interact with the users table in the database.

2. Relationships

Eloquent makes it easy to define relationships between different models. For example, a User might have many Post models.

3. Query Builder

Eloquent provides an expressive and easy-to-use query builder to interact with the database. You can perform CRUD operations with simple methods.

4. Mutators and Accessors

Eloquent allows you to define mutators and accessors to modify how attributes are retrieved or set.

5. Migrations

Laravel uses migrations to manage database schema changes. This ensures that your database structure is consistent across different environments.
