What is laravel eloquent model

Laravel eloquent is an object-relational mapper so it is also called eloquent orm model it is used to interact with databases and perform insert, update and delete operations. In simply it interacts activeRecords from the database. Model is a layer between database and controller

Models are listed in App/Model directory and you also change this by customizing in composer.json file but this is not the right way laravel provides default Model directory that are good and secure.

Laravel all commands to create model

The basic command to create a model is php artisan make:model Student

Or

php artisan make:model Student -migration

And if you create model, migration and controller by single command than use php artisan make:model Student -mc

Eloquent model structure

<?php  
  
namespace App;  
  
use Illuminate\Database\Eloquent\Model;  
  
class Student extends Model  
{  
    //  
} 

Laravel eloquent vs query builder

The eloquent model provides relationships but it slow execution compare to query builder in simple queries but when query have more complex and data come from different relationships than eloquent model better because it provides a good relationship methods.
