// Enterprise-grade column customization
$table->string('title', 200)
      ->comment('SEO-optimized page title')     // Self-documenting schemas
      ->columnCharset('utf8mb4')               // Custom character sets
      ->columnCollation('utf8mb4_unicode_ci') // Specific collations
      ->nullable()                             // Allow NULL values
      ->default('Untitled')                    // Default values
      ->after('slug')                          // Position after column
      ->invisible();                           // Hidden from SELECT *

// Numeric modifiers
$table->decimal('balance', 15, 2)
      ->unsigned()                             // Only positive values
      ->default(0.00)
      ->comment('Account balance in USD');

// Timestamp helpers
$table->timestamp('created_at')->useCurrent()          // DEFAULT CURRENT_TIMESTAMP
      ->timestamp('updated_at')->useCurrentOnUpdate()  // ON UPDATE CURRENT_TIMESTAMP
      ->timestamp('deleted_at')->nullable();            // Soft deletes

🧠 Intelligent Migration System

SimpleMDB analyzes your migration names and generates context-aware templates:

// Migration: "create_users_table" 
// ✨ Auto-generates complete user table with modern features
php artisan migration:create create_users_table

// Migration: "add_email_to_customers"
// ✨ Auto-detects VARCHAR(255) for email + unique constraint
php artisan migration:create add_email_to_customers

// Migration: "add_is_active_to_posts" 
// ✨ Auto-detects BOOLEAN type for is_* fields
php artisan migration:create add_is_active_to_posts

Generated Template Example:

// Intelligently generated based on migration name
public function up(): void
{
    $this->createTable('users', function($table) {
        $table->increments('id');
        $table->string('name')->comment('Full name');
        $table->string('email')->unique();
        $table->timestamp('email_verified_at')->nullable();
        $table->string('password');
        $table->date('birth_date')->nullable();
        $table->enum('status', ['active', 'inactive', 'pending'])->default('active');
        $table->json('preferences')->nullable();
        $table->ipAddress('last_login_ip')->nullable();
        $table->rememberToken();                // Laravel-style auth token
        $table->timestamps();                   // created_at, updated_at
        $table->softDeletes();                  // deleted_at
    });
}

🛡️ Enterprise Security Features

100% SQL Injection Prevention

// All identifiers properly escaped
$table->string('user-name')        // Becomes `user-name` in SQL
      ->comment("User's full name"); // Becomes COMMENT 'User\'s full name'

// All values parameterized  
$table->enum('status', ["'admin'", '"user"'])  // Properly escaped enum values
      ->default("'pending'");                   // Safe default handling

Comprehensive Input Validation

// 65+ MySQL reserved words detected
$table->string('select');     // ❌ Error: 'select' is a MySQL reserved word

// Length validation with helpful messages
$table->string('title', 70000); // ❌ Error: VARCHAR length must be between 1 and 65535, got 70000

// Type compatibility checking
$table->json('data')->unsigned(); // ❌ Error: unsigned() can only be used with numeric columns

🚀 Quick Start Guide

1. Basic Database Connection

<?php
require_once 'vendor/autoload.php';

use SimpleMDB\DatabaseFactory;
use SimpleMDB\SchemaBuilder;
use SimpleMDB\SimpleQuery;

// Create database connection
$db = DatabaseFactory::create('pdo', 'localhost', 'root', 'password', 'myapp');

// Test connection
if ($db->ping()) {
    echo "Connected successfully!\n";
} else {
    echo "Connection failed!\n";
}

2. Create Your First Table

// Initialize schema builder
$schema = new SchemaBuilder($db);

// Create a users table with modern features
$schema->increments('id')
       ->string('name', 100)->comment('User full name')
       ->string('email', 150)->unique()
       ->string('password', 255)
       ->boolean('is_active')->default(true)
       ->json('preferences')->nullable()
       ->ipAddress('last_login_ip')->nullable()
       ->timestamps() // created_at, updated_at
       ->softDeletes() // deleted_at
       ->createTable('users');

echo "✅ Users table created successfully!\n";

3. Insert Data

// Insert a single user
$userId = SimpleQuery::create()
    ->insert('users')
    ->values([
        'name' => 'John Doe',
        'email' => 'john@example.com',
        'password' => password_hash('secret123', PASSWORD_DEFAULT),
        'is_active' => true,
        'preferences' => json_encode(['theme' => 'dark', 'notifications' => true])
    ])
    ->execute($db);

echo "✅ User created with ID: $userId\n";

4. Query Data

// Find active users
$users = SimpleQuery::create()
    ->select(['id', 'name', 'email', 'created_at'])
    ->from('users')
    ->where('is_active = ?', [true])
    ->where('deleted_at IS NULL')
    ->orderBy('created_at DESC')
    ->limit(10)
    ->execute($db);

echo "Found " . count($users) . " active users\n";
foreach ($users as $user) {
    echo "- {$user['name']} ({$user['email']})\n";
}

5. Update Data

// Update user preferences
$affected = SimpleQuery::create()
    ->update('users')
    ->set([
        'preferences' => json_encode(['theme' => 'light', 'notifications' => false]),
        'updated_at' => date('Y-m-d H:i:s')
    ])
    ->where('id = ?', [$userId])
    ->execute($db);

echo "✅ Updated $affected user(s)\n";

6. Your First Migration

use SimpleMDB\Migrations\MigrationManager;

// Initialize migration manager
$migrations = new MigrationManager($db);

// Create a migration (generates intelligent template)
$migrationFile = $migrations->create('create_blog_posts_table');
echo "✅ Migration created: $migrationFile\n";

// Run all pending migrations
$migrations->migrate();
echo "✅ All migrations completed!\n";

// Check migration status
foreach ($migrations->status() as $migration) {
    echo "📄 {$migration['name']}: {$migration['status']}\n";
}

🏗️ Schema Builder

The Schema Builder is SimpleMDB's powerful database schema management system that provides enterprise-grade features for creating, modifying, and managing database tables.

Core Concepts

1. Schema Builder Instance

use SimpleMDB\SchemaBuilder;

// Create schema builder instance
$schema = new SchemaBuilder($db);

// Check if table exists
if ($schema->hasTable('users')) {
    echo "Users table exists\n";
}

// Get table column information
$columns = $schema->getColumns('users');
foreach ($columns as $column) {
    echo "Column: {$column['name']} ({$column['type']})\n";
}

// Drop table if exists
$schema->dropIfExists('old_table');

2. Creating Tables

// Method 1: Fluent interface (recommended)
$schema->increments('id')
       ->string('name', 100)->comment('User full name')
       ->string('email', 150)->unique()
       ->timestamps()
       ->createTable('users');

// Method 2: Callback syntax
$schema->createTable('posts', function($table) {
    $table->increments('id');
    $table->string('title', 200);
    $table->text('content');
    $table->unsignedInteger('user_id');
    $table->timestamps();
    
    // Add foreign key constraint
    $table->foreignKey('user_id', 'users', 'id');
});

// Method 3: Advanced table creation
$schema->createTable('products', function($table) {
    $table->increments('id');
    $table->string('sku', 50)->unique();
    $table->string('name', 200);
    $table->text('description')->nullable();
    $table->decimal('price', 10, 2)->unsigned();
    $table->json('attributes')->nullable();
    $table->enum('status', ['active', 'inactive', 'discontinued'])->default('active');
    $table->timestamps();
    
    // Indexes
    $table->index(['name'], 'product_name_idx');
    $table->index(['status', 'price'], 'status_price_idx');
    $table->unique(['sku'], 'unique_sku');
});

3. Modifying Tables

// Add columns to existing table
$schema->addColumn('users', 'phone', 'string', 20, [
    'nullable' => true,
    'comment' => 'User phone number'
]);

// Modify existing column
$schema->modifyColumn('users', 'phone', 'string', 25, [
    'nullable' => false,
    'default' => ''
]);

// Drop column
$schema->dropColumn('users', 'phone');

// Rename column
$schema->renameColumn('users', 'phone', 'mobile_phone');

// Add index
$schema->addIndex('users', ['email'], 'email_idx');

// Drop index
$schema->dropIndex('users', 'email_idx');

4. Table Operations

// Rename table
$schema->renameTable('old_users', 'users');

// Truncate table (remove all data)
$schema->truncateTable('temporary_data');

// Drop table
$schema->dropTable('unused_table');

// Drop table if exists
$schema->dropIfExists('maybe_exists');

// Get table schema
$tableSchema = $schema->getTableSchema('users');
print_r($tableSchema);

Advanced Schema Features

1. Constraints and Relationships

$schema->createTable('orders', function($table) {
    $table->increments('id');
    $table->unsignedInteger('user_id');
    $table->decimal('total', 10, 2);
    $table->timestamps();
    
    // Foreign key constraint
    $table->foreignKey('user_id', 'users', 'id', 'CASCADE', 'CASCADE');
    
    // Composite foreign key
    $table->foreignKey(['user_id', 'status'], 'user_status', ['user_id', 'status']);
    
    // Check constraint
    $table->checkConstraint('total > 0', 'positive_total');
});

// Add foreign key to existing table
$schema->addForeignKey('orders', 'user_id', 'users', 'id');

// Drop foreign key
$schema->dropForeignKey('orders', 'orders_user_id_foreign');

2. Indexes and Performance

$schema->createTable('search_index', function($table) {
    $table->increments('id');
    $table->string('title', 200);
    $table->text('content');
    $table->string('category', 50);
    $table->timestamps();
    
    // Regular index
    $table->index(['category'], 'category_idx');
    
    // Composite index
    $table->index(['category', 'created_at'], 'category_date_idx');
    
    // Unique index
    $table->unique(['title'], 'unique_title');
    
    // Full-text index
    $table->fullTextIndex(['title', 'content'], 'search_fulltext');
    
    // Partial index (MySQL 8.0+)
    $table->partialIndex(['title'], 'active_titles', 'status = "active"');
});

3. Advanced Column Types

$schema->createTable('analytics', function($table) {
    $table->increments('id');
    
    // Geographic data
    $table->point('location');          // POINT type for coordinates
    $table->polygon('area');            // POLYGON type for regions
    $table->lineString('route');        // LINESTRING type for paths
    
    // Large objects
    $table->mediumText('report');       // Up to 16MB text
    $table->longText('log_data');       // Up to 4GB text
    $table->mediumBlob('image');        // Up to 16MB binary
    $table->longBlob('video');          // Up to 4GB binary
    
    // Network data
    $table->ipAddress('client_ip');     // IPv4/IPv6
    $table->macAddress('device_mac');   // MAC address
    
    // JSON and document storage
    $table->json('config');             // JSON data
    $table->jsonb('metadata');          // Binary JSON (if supported)
    
    // Time-series data
    $table->timestamp('event_time', 6); // Microsecond precision
    $table->time('duration', 3);        // Millisecond precision
    $table->year('fiscal_year');        // Year only
});

Schema Validation and Security

1. Column Name Validation

// SimpleMDB validates all column names
try {
    $schema->string('user-name');  // ✅ Valid: hyphens allowed
    $schema->string('user_name');  // ✅ Valid: underscores allowed
    $schema->string('userName');   // ✅ Valid: camelCase allowed
    $schema->string('user name');  // ❌ Invalid: spaces not allowed
    $schema->string('select');     // ❌ Invalid: MySQL reserved word
} catch (SimpleMDB\Exceptions\SchemaException $e) {
    echo "Schema error: " . $e->getMessage();
}

2. Data Type Validation

// Length validation
try {
    $schema->string('title', 70000);     // ❌ Invalid: VARCHAR max is 65535
    $schema->decimal('price', 70, 2);    // ❌ Invalid: DECIMAL max precision is 65
    $schema->enum('status', []);         // ❌ Invalid: ENUM needs values
} catch (SimpleMDB\Exceptions\SchemaException $e) {
    echo "Validation error: " . $e->getMessage();
}

3. Modifier Compatibility

// Type compatibility checking
try {
    $schema->json('data')->unsigned();   // ❌ Invalid: JSON can't be unsigned
    $schema->text('content')->after('id'); // ✅ Valid: positioning modifier
    $schema->string('name')->invisible(); // ✅ Valid: MySQL 8.0+ feature
} catch (SimpleMDB\Exceptions\SchemaException $e) {
    echo "Modifier error: " . $e->getMessage();
}

Performance Optimization

1. Efficient Schema Building

// Batch operations for better performance
$schema->startBatch();

// Add multiple columns efficiently
$schema->string('first_name', 50);
$schema->string('last_name', 50);
$schema->string('email', 150);
$schema->date('birth_date');

// Execute all operations at once
$schema->createTable('users');
$schema->commitBatch();

2. Index Strategy

$schema->createTable('user_activities', function($table) {
    $table->increments('id');
    $table->unsignedInteger('user_id');
    $table->string('activity_type', 50);
    $table->timestamp('created_at');
    
    // Optimized indexing strategy
    $table->index(['user_id', 'created_at'], 'user_timeline');      // Timeline queries
    $table->index(['activity_type', 'created_at'], 'type_timeline'); // Type filtering
    $table->index(['created_at'], 'created_at_idx');                 // Date range queries
});

Basic Schema Building Example

use SimpleMDB\DatabaseFactory;
use SimpleMDB\SchemaBuilder;

// Connect to database
$db = DatabaseFactory::create('pdo', 'localhost', 'root', 'password', 'database');
$schema = new SchemaBuilder($db);

// Create modern table with enterprise features
$schema->increments('id')
       ->string('name')->comment('User full name')
       ->string('email')->unique()
       ->ipAddress('last_ip')->nullable()
       ->json('preferences')->nullable()
       ->enum('status', ['active', 'inactive'])->default('active')
       ->timestamps()
       ->softDeletes()
       ->createTable('users');

🔄 Migration System

SimpleMDB's migration system provides intelligent, context-aware database schema management with automatic template generation and comprehensive rollback support.

Core Migration Concepts

1. Migration Manager

use SimpleMDB\Migrations\MigrationManager;

// Initialize migration manager
$migrations = new MigrationManager($db);

// Set migration directory (optional)
$migrations->setMigrationDirectory('./database/migrations');

// Set migration table name (optional)
$migrations->setMigrationTable('schema_migrations');

2. Creating Migrations

// Create new migration with intelligent template
$file = $migrations->create('create_users_table');
echo "Migration created: $file\n";

// Create with custom template
$file = $migrations->create('add_email_to_customers', [
    'template' => 'add_column',
    'table' => 'customers',
    'column' => 'email',
    'type' => 'string'
]);

3. Running Migrations

// Run all pending migrations
$migrations->migrate();

// Run specific number of migrations
$migrations->migrate(5);

// Run migrations with output
$migrations->migrate(null, true); // true for verbose output

4. Migration Status

// Check migration status
$status = $migrations->status();
foreach ($status as $migration) {
    echo sprintf("%-40s %s\n", $migration['name'], $migration['status']);
}

// Check if migrations are pending
if ($migrations->hasPendingMigrations()) {
    echo "Pending migrations found!\n";
}

Intelligent Template Generation

SimpleMDB analyzes migration names and generates context-aware templates automatically.

Pattern Recognition Examples

1. Create Table Pattern

// Migration name: "create_users_table"
$migrations->create('create_users_table');

Generated Template:

<?php
use SimpleMDB\Migrations\Migration;

class CreateUsersTable extends Migration
{
    public function up(): void
    {
        $this->createTable('users', function($table) {
            $table->increments('id');
            $table->string('name')->comment('Full name');
            $table->string('email')->unique();
            $table->timestamp('email_verified_at')->nullable();
            $table->string('password');
            $table->boolean('is_active')->default(true);
            $table->json('preferences')->nullable();
            $table->rememberToken();
            $table->timestamps();
            $table->softDeletes();
            
            $table->index(['email']);
            $table->index(['created_at']);
        });
    }
    
    public function down(): void
    {
        $this->dropIfExists('users');
    }
}

2. Add Column Pattern

// Migration name: "add_email_to_customers"
$migrations->create('add_email_to_customers');

Generated Template:

<?php
use SimpleMDB\Migrations\Migration;

class AddEmailToCustomers extends Migration
{
    public function up(): void
    {
        $this->addColumn('customers', function($table) {
            $table->string('email', 150)
                  ->unique()
                  ->comment('Customer email address')
                  ->after('name'); // Intelligent positioning
        });
    }
    
    public function down(): void
    {
        $this->dropColumn('customers', 'email');
    }
}

3. Add Index Pattern

// Migration name: "add_email_index_to_users"
$migrations->create('add_email_index_to_users');

Generated Template:

<?php
use SimpleMDB\Migrations\Migration;

class AddEmailIndexToUsers extends Migration
{
    public function up(): void
    {
        $this->addIndex('users', ['email'], 'users_email_index');
    }
    
    public function down(): void
    {
        $this->dropIndex('users', 'users_email_index');
    }
}

4. Modify Table Pattern

// Migration name: "modify_products_table"
$migrations->create('modify_products_table');

Generated Template:

<?php
use SimpleMDB\Migrations\Migration;

class ModifyProductsTable extends Migration
{
    public function up(): void
    {
        $this->modifyTable('products', function($table) {
            // Add new columns
            $table->string('slug', 200)->unique()->after('name');
            $table->decimal('compare_price', 10, 2)->unsigned()->nullable()->after('price');
            $table->boolean('featured')->default(false)->after('active');
            $table->json('seo_metadata')->nullable();
            
            // Modify existing columns
            $table->modifyColumn('description', 'text', null, ['nullable' => true]);
            $table->modifyColumn('price', 'decimal', [10, 2], ['unsigned' => true]);
            
            // Add indexes
            $table->index(['slug']);
            $table->index(['featured', 'active']);
            $table->index(['price', 'compare_price']);
        });
    }
    
    public function down(): void
    {
        $this->modifyTable('products', function($table) {
            $table->dropColumn(['slug', 'compare_price', 'featured', 'seo_metadata']);
            $table->dropIndex('products_slug_index');
            $table->dropIndex('products_featured_active_index');
            $table->dropIndex('products_price_compare_price_index');
        });
    }
}

Smart Type Detection

SimpleMDB automatically detects appropriate column types based on column names:

Column Name Pattern	Detected Type	Example
`*_id`	`unsignedInteger`	`user_id` → `unsignedInteger('user_id')`
`*_uuid`	`uuid`	`external_uuid` → `uuid('external_uuid')`
`*_at`	`timestamp`	`created_at` → `timestamp('created_at')`
`*_on`	`date`	`born_on` → `date('born_on')`
`is_*`	`boolean`	`is_active` → `boolean('is_active')`
`has_*`	`boolean`	`has_premium` → `boolean('has_premium')`
`*_count`	`unsignedInteger`	`view_count` → `unsignedInteger('view_count')`
`*_price`	`decimal`	`unit_price` → `decimal('unit_price', 10, 2)`
`*_amount`	`decimal`	`total_amount` → `decimal('total_amount', 10, 2)`
`*_email`	`string`	`contact_email` → `string('contact_email', 150)`
`*_url`	`string`	`website_url` → `string('website_url', 500)`
`*_ip`	`ipAddress`	`client_ip` → `ipAddress('client_ip')`
`*_mac`	`macAddress`	`device_mac` → `macAddress('device_mac')`
`*_data`	`json`	`config_data` → `json('config_data')`
`*_metadata`	`json`	`user_metadata` → `json('user_metadata')`

class CreateEcommerceTables extends Migration
{
    public function up(): void
    {
        // Create products table
        $this->createTable('products', function($table) {
            $table->increments('id');
            $table->string('sku', 50)->unique();
            $table->string('name', 200);
            $table->text('description')->nullable();
            $table->decimal('price', 10, 2)->unsigned();
            $table->json('attributes')->nullable();
            $table->boolean('active')->default(true);
            $table->timestamps();
            
            $table->index(['active', 'created_at']);
            $table->fullTextIndex(['name', 'description']);
        });

            $table->increments('id');
            $table->unsignedInteger('product_id');
            $table->unsignedInteger('category_id');
            $table->timestamps();
            
            $table->unique(['product_id', 'category_id']);
            $table->foreignKey('product_id', 'products', 'id', 'CASCADE');
            $table->foreignKey('category_id', 'categories', 'id', 'CASCADE');
        });
        
        // Create product_reviews table
        $this->createTable('product_reviews', function($table) {
            $table->increments('id');
            $table->unsignedInteger('product_id');
            $table->unsignedInteger('user_id');

Migration CLI Commands

Command Examples

# Create new migration
php migrate create create_users_table

# Run all pending migrations
php migrate up

# Rollback last migration
php migrate down

# Check migration status
php migrate status

# Show migration history
php migrate history

# Reset all migrations (dangerous!)

# Dry run (show SQL without executing)
php migrate dry-run

Best Practices

1. Migration Naming

// ✅ Good naming conventions
create_users_table
add_email_to_customers
modify_products_table
drop_old_logs_table
add_index_to_orders
remove_unused_columns_from_posts

// ❌ Poor naming conventions
fix_stuff
update_db
migration_v2
temp_changes

2. Safe Migration Practices

public function up(): void
{
    // ✅ Always check if table exists
    if (!$this->hasTable('users')) {
        $this->createTable('users', function($table) {
            // Table definition
        });
    }
    
    // ✅ Check if column exists before adding
    if (!$this->hasColumn('users', 'email')) {
        $this->addColumn('users', 'email', 'string', 150);
    }
    
    // ✅ Use transactions for multiple operations
    $this->beginTransaction();
    try {
        $this->addColumn('users', 'status', 'string', 20);
        $this->addIndex('users', ['status']);
        $this->commit();
    } catch (Exception $e) {
        $this->rollback();
        throw $e;
    }
}

3. Rollback Safety

public function down(): void
{
    // ✅ Always provide proper rollback
    $this->dropColumn('users', 'email');
    
    // ✅ Check before dropping
    if ($this->hasTable('temporary_table')) {
        $this->dropTable('temporary_table');
    }
    
    // ✅ Drop indexes before dropping columns
    $this->dropIndex('users', 'users_email_index');
    $this->dropColumn('users', 'email');
}
