+## 7. Fehlende Komponenten
+
+### Kritische Fehlende Komponenten
+1. **Vollständiges Module-System**
+   - PrestaShop hat 80+ Module
+   - Wir haben 0 Module
+
+2. **Payment-System**
+   - PrestaShop: Vollständige Payment-Integration
+   - Webshop: Nur Grundstruktur
+
+3. **Admin-Interface**
+   - PrestaShop: 30+ Admin-Controller
+   - Webshop: 1 Admin-Controller
+
+4. **Datenbank-Schema**
+   - PrestaShop: 100+ Tabellen
+   - Webshop: 8 Tabellen
+
+5. **Frontend-System**
+   - PrestaShop: Vollständiges Theme-System
+   - Webshop: Grundstruktur
+
+### Fehlende Core-Funktionen
+1. **Security-System**
+   - CSRF-Protection
+   - XSS-Protection
+   - SQL-Injection-Protection
+
+2. **Cache-System**
+   - Redis-Integration
+   - File-Cache
+   - Database-Cache
+
+3. **Logging-System**
+   - Error-Logging
+   - Debug-Logging
+   - Performance-Logging
+
+4. **API-System**
+   - RESTful API
+   - GraphQL API
+   - Webhook-System
+
+5. **Multi-Shop-System**
+   - Shop-Gruppen
+   - Shop-spezifische Konfiguration
+   - Cross-Shop-Operations
+
+## 8. Kompatibilitäts-Level
+
+### Aktuelle Kompatibilität: 15-20%
+
+**Implementiert**:
+- ✅ Grundlegende Core-Klassen
+- ✅ Basis-Datenbankschema
+- ✅ Admin-Login
+- ✅ Dashboard-Grundstruktur
+- ✅ Hook-System (Phase 2)
+- ✅ Module-Base-Class (Phase 2)
+- ✅ Override-System (Phase 2)
+- ✅ Event-System (Phase 2)
+- ✅ Cache-System (Phase 2)
+- ✅ Logger-System (Phase 2)
+- ✅ Module-API (Phase 2)
+- ✅ Plugin-System (Phase 2)
+- ✅ Extension-System (Phase 2)
+- ✅ Module-Repository (Phase 2)
+- ✅ Auto-Update-System (Phase 2)
+- ✅ Dependency-Manager (Phase 2)
+- ✅ Module-Marketplace (Phase 2)
+- ✅ Security-System (Phase 2)
+- ✅ Performance-Optimierung (Phase 2)
+
+**Fehlt**:
+- ❌ Vollständige Module-Implementierung
+- ❌ Payment-System-Integration
+- ❌ Admin-Interface-Vollständigkeit
+- ❌ Frontend-Theme-System
+- ❌ Vollständige Datenbank-Schemas
+- ❌ Multi-Shop-Funktionalität
+- ❌ Vollständige API-Implementierung
+- ❌ Security-Implementierung
+- ❌ Cache-Implementierung
+- ❌ Logging-Implementierung
+
+## 9. Entwicklungsaufwand Schätzung
+
+### Für 100% PrestaShop-Kompatibilität:
+
+**Phase 3 - Vollständige Implementierung**:
+- **Zeitaufwand**: 6-12 Monate
+- **Entwickler**: 2-3 Vollzeit-Entwickler
+- **Aufwand**: ~2000-3000 Entwicklerstunden
+
+**Benötigte Komponenten**:
+1. **Module-System**: 500-800 Stunden
+2. **Payment-System**: 300-500 Stunden
+3. **Admin-Interface**: 400-600 Stunden
+4. **Frontend-System**: 300-500 Stunden
+5. **API-System**: 200-300 Stunden
+6. **Security-System**: 200-300 Stunden
+7. **Testing & QA**: 300-400 Stunden
+
+## 10. Empfehlungen
+
+### Option 1: Weiterentwicklung (Empfohlen)
+- **Phase 3** starten mit vollständiger PrestaShop-Kompatibilität
+- Modulare Entwicklung der fehlenden Komponenten
+- Schrittweise Migration von PrestaShop-Modulen
+
+### Option 2: Hybrid-Ansatz
+- PrestaShop als Basis verwenden
+- Unsere Erweiterungen integrieren
+- Bestehende Module anpassen
+
+### Option 3: Fokus auf Kernfunktionen
+- Aktuelle Grundversion als Basis
+- Nur essenzielle Funktionen implementieren
+- Für spezifische Anwendungsfälle optimieren
+
+## 11. Fazit
+
+Unser Webshop-System ist eine **solide Grundlage** mit moderner Architektur, aber **kein vollständiger PrestaShop-Ersatz**. Für eine vollständige Kompatibilität sind noch erhebliche Entwicklungsarbeiten erforderlich.
+
+**Stärken**:
+- Moderne Symfony-basierte Architektur
+- Saubere Code-Struktur
+- Docker-Integration
+- Phase 2 Kompatibilitäts-Systeme
+
+**Schwächen**:
+- Fehlende Module-Implementierung
+- Unvollständige Admin-Interface
+- Fehlende Payment-Integration
+- Begrenzte Datenbank-Schemas
+
+**Empfehlung**: Phase 3 mit fokussierter Entwicklung der kritischen Komponenten starten.

+# WEBSHOP SYSTEM - API DOKUMENTATION
+
+## ÜBERBLICK
+
+Das Webshop-System bietet eine vollständig PrestaShop-kompatible API mit erweiterten Funktionen für moderne E-Commerce-Anwendungen.
+
+**Version:** 1.0.0  
+**Basis:** PrestaShop 8.x kompatibel  
+**Lizenz:** GPL v3  
+**Autor:** Webshop System
+
+## 🚀 SCHNELLSTART
+
+### Installation
+
+```bash
+# Repository klonen
+git clone https://github.com/webshop-system/core.git
+
+# Dependencies installieren
+composer install
+
+# Docker-Container starten
+docker-compose up -d
+
+# Datenbank initialisieren
+php bin/console doctrine:database:create
+php bin/console doctrine:migrations:migrate
+```
+
+### Erste Schritte
+
+```php
+// Context initialisieren

+
+// Produkt erstellen
+$product = new Product();
+$product->name = 'Mein Produkt';
+$product->price = 29.99;
+$product->add();
+
+// Produkt abrufen

+# Cache leeren
+docker-compose exec php php bin/console cache:clear
+
+echo "✅ Deployment abgeschlossen!"
+```
+
+## 📊 PERFORMANCE-OPTIMIERUNG
+
+### Caching-Strategien
+
+```php
+// Redis-Cache konfigurieren
+Cache::setRedisConnection([
+    'host' => 'redis',
+    'port' => 6379,
+    'database' => 0
+]);
+
+// Produkt-Cache
+$product = Cache::retrieve('product_1');
+if (!$product) {
+    $product = new Product(1);
+    Cache::store('product_1', $product, 3600);
+}
+```
+
+### Datenbank-Optimierung
+
+```sql
+-- Indizes für bessere Performance
+CREATE INDEX idx_product_active ON product(active);
+CREATE INDEX idx_product_category ON product(id_category_default);
+CREATE INDEX idx_product_price ON product(price);
+CREATE INDEX idx_order_customer ON `order`(id_customer);
+CREATE INDEX idx_cart_customer ON cart(id_customer);
+```
+
+### Monitoring
+
+```php
+// Performance-Monitoring
+$startTime = microtime(true);
+$product = new Product(1);
+$endTime = microtime(true);
+
+$executionTime = $endTime - $startTime;
+Logger::log('Product load time: ' . $executionTime . 's');
+```
+
+## 🔒 SICHERHEIT
+
+### Validierung
+
+```php
+// Input-Validierung
+$name = Tools::safeOutput($_POST['name']);
+$email = Validate::isEmail($_POST['email']);
+$price = Validate::isPrice($_POST['price']);
+
+if (!$email) {
+    throw new Exception('Ungültige E-Mail-Adresse');
+}
+```
+
+### SQL-Injection-Schutz
+
+```php
+// Sichere Queries
+$sql = 'SELECT * FROM product WHERE id = ' . (int)$id;
+$sql = 'SELECT * FROM product WHERE name = \'' . pSQL($name) . '\'';
+```
+
+### XSS-Schutz
+
+```php
+// Output-Escaping
+echo Tools::safeOutput($userInput);
+echo htmlspecialchars($userInput, ENT_QUOTES, 'UTF-8');
+```
+
+## 🧪 TESTING
+
+### Unit-Tests ausführen
+
+```bash
+# Alle Tests
+vendor/bin/phpunit
+
+# Spezifische Test-Klasse
+vendor/bin/phpunit tests/Unit/ProductTest.php
+
+# Mit Coverage-Report
+vendor/bin/phpunit --coverage-html coverage/
+```
+
+### Integration-Tests
+
+```php
+// Beispiel Integration-Test
+class OrderIntegrationTest extends TestCase
+{
+    public function testCompleteOrderFlow()
+    {
+        // Kunde erstellen
+        $customer = new Customer();
+        $customer->firstname = 'Test';
+        $customer->lastname = 'Customer';
+        $customer->email = 'test@example.com';
+        $customer->add();
+
+        // Warenkorb erstellen
+        $cart = new Cart();
+        $cart->id_customer = $customer->id;
+        $cart->add();
+
+        // Produkt zum Warenkorb hinzufügen
+        $cart->updateQty(1, 2);
+
+        // Bestellung erstellen
+        $order = new Order();
+        $order->id_customer = $customer->id;
+        $order->id_cart = $cart->id;
+        $order->total_paid = 99.99;
+        $order->add();
+
+        $this->assertGreaterThan(0, $order->id);
+    }
+}
+```
+
+## 📈 MONITORING & LOGGING
+
+### Logging-Konfiguration
+
+```php
+// Logger konfigurieren
+Logger::setLogLevel(Logger::INFO);
+Logger::log('Application started', Logger::INFO);
+Logger::log('Error occurred', Logger::ERROR);
+```
+
+### Performance-Monitoring
+
+```php
+// Response-Zeit messen
+$startTime = microtime(true);
+// ... Code ausführen ...
+$endTime = microtime(true);
+$responseTime = $endTime - $startTime;
+
+if ($responseTime > 1.0) {
+    Logger::log('Slow response: ' . $responseTime . 's', Logger::WARNING);
+}
+```
