Laravel Query Builder is a fluent, chainable interface for building SQL queries programmatically without writing raw SQL.
Instead of typing plain SQL like:
SELECT * FROM users WHERE active = 1 ORDER BY name ASC;
You can write it in Query Builder:
$users = DB::table('users')
->where('active', 1)
->orderBy('name', 'asc')
->get();
✅ Security (Prevents SQL Injection) → Automatically binds parameters.
✅ Readability → Cleaner, chainable syntax.
✅ Portability → Works across different database drivers (MySQL, PostgreSQL, SQLite, SQL Server).
✅ Maintainability → Easier to maintain/update queries than raw SQL.
✅ Integration with Laravel → Works smoothly with Eloquent ORM, migrations, transactions, etc.
