Laravel-Specific MySQL Features

// MySQL-specific Laravel migration example
Schema::create('products', function (Blueprint $table) {
    $table->id();
    $table->string('name');
    $table->decimal('price', 10, 2);
    $table->json('attributes'); // Native JSON support
    $table->fullText(['name', 'description']); // Full-text search
    $table->timestamps();
    
    $table->index(['category_id', 'created_at']);
});

MySQL's JSON data type support in Laravel enables flexible schema design while maintaining relational integrity. The full-text search capabilities provide built-in search functionality without requiring external search engines for simple use cases.

Hosting and Deployment Advantages

Most shared hosting providers offer MySQL by default, making deployment simpler and more cost-effective for smaller projects. The widespread adoption means better tooling, monitoring solutions, and third-party integrations.

• Advanced constraint checking
• Better handling of concurrent transactions
• Superior referential integrity
• More robust transaction isolation levels

Advanced Data Types and Features

PostgreSQL offers a rich set of data types that can significantly enhance Laravel applications dealing with complex data structures.

// PostgreSQL-specific Laravel migration
Schema::create('analytics', function (Blueprint $table) {
    $table->id();
    $table->jsonb('user_data'); // Binary JSON for better performance
    $table->geometry('location'); // Spatial data types
    $table->array('tags'); // Native array support
    $table->uuid('session_id');
    $table->dateRange('active_period'); // Range types
    $table->timestamps();
    
    $table->index('user_data', null, 'gin'); // GIN index for JSONB
});
