Message:

I want to combine multiple databases in my system. Most of the time the database is MySQL; but it may differ in future i.e. Admin can generate such a reports which is use source of heterogeneous database system.

So my question is does Laravel provide any Facade to deal with such situations? Or any other framework have more suitable capabilities for problem is?

My Answer:
In Laravel, you can easily work with multiple databases by defining multiple database connections in your `config/database.php` file.

Here's an example of how you can define multiple database connections in Laravel:

php
'connections' => [

'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'database' => env('DB_DATABASE', 'database1'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],

'mysql2' => [
'driver' => 'mysql',
'host' => env('DB_HOST2', 'localhost'),
'database' => env('DB_DATABASE2', 'database2'),
'username' => env('DB_USERNAME2', 'root'),
'password' => env('DB_PASSWORD2', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],

],


You can then specify which database connection to use in your models by setting the `$connection` property:

php
class User extends Model
{
protected $connection = 'mysql2';
}


You can also switch between database connections dynamically using the `DB` facade:

php
DB::connection('mysql2')->table('table_name')->get();


Overall, Laravel provides a flexible and easy way to work with multiple databases in your application.
