Understanding ORM vs DB Query Builder in Laravel

First, we introduce what ORM (Object‑Relational Mapping) and DB facade (query builder) are, both used for database operations but with different usage patterns.

ORM provides a mapping between relational tables and business objects, allowing developers to work with model attributes and methods instead of raw SQL. Its main benefits are simplicity, intuitiveness, and easier maintenance, though careless use can generate unexpected SQL.

The DB facade is essentially a query builder that converts parameters into SQL statements, supporting complex queries, closures, chainable methods, and transaction handling, similar to writing raw SQL manually.

For small projects either ORM or DB facade can be chosen based on personal preference; for larger projects they are often combined, e.g., using ORM for most operations while employing the DB facade for transaction control.

ORM example (requires a Model):

orderBy('name', 'desc')->take(10)->get();
$user = App\User::find(1);
$user = App\User::where('active', 1)->first();
$count = App\User::where('active', 1)->count();
$max = App\User::where('active', 1)->max('price');
$newUser = new User;
$newUser->name = $request->name;
$newUser->save();
$user = App\User::find(1);
$user->delete();
App\User::destroy(1);
App\User::destroy([1, 2, 3]);
App\User::destroy(1, 2, 3);

DB facade example (no Model required):

$users = DB::table('users')->where('active', 1)
          ->orderBy('name', 'desc')
          ->limit(10)
          ->get()
          ->toArray();

$user = DB::table('users')->where('user_id',1)->first();
$user = DB::table('users')->where('active',1)->first();
$count = DB::table('users')->where('active',1)->count();
$max = DB::table('users')->where('active',1)->max('price');

data = [
    'name' => $request->name,
];
$rest = DB::table('users')->insert($data);

DB::table('users')->where('user_id',1)->delete();
DB::table('users')->delete(['user_id',1]);

DB::beginTransaction();
if(DB::table('users')->where(['user_id',1])->update()){
    return false;
    DB::rollBack();
}
DB::commit();

In summary, the choice between ORM and DB facade depends on project size and specific requirements; both can be used together to leverage their respective strengths.
