🔴 Problemas del Diseño Actual

1. Tabla user_teams sobrecargada (22 campos)

-- Mezcla múltiples responsabilidades:
- Pivot (user ↔ team) ✅
- Worker schedule ❌ (debería ser tabla separada)
- Worker compensation ❌ (debería ser tabla separada)
- Worker specialties ❌ (debería ser tabla separada)
- Work availability ❌ (debería ser tabla separada)

2. Tabla teams sobrecargada (50+ campos)

-- Mezcla:
- Info básica del negocio ✅
- Configuración de booking ❌ (tabla separada)
- Configuración de pagos ❌ (tabla separada)
- Configuración de notificaciones ❌ (JSON gigante)
- Analytics settings ❌ (tabla separada)
- Website settings ❌ (tabla separada)
- Billing info ❌ (tabla separada)

3. Tabla users con campos redundantes

-- Mezcla:
- Usuario base ✅
- Cliente profile ❌ (client_classification, etc.)
- Security fields innecesarios en base ❌

4. Sistema de finanzas fragmentado

-- 15 tablas de finanzas:
payments, cash_registers, cash_movements, transactions,
transaction_logs, worker_earnings, worker_payments,
worker_payment_bonuses, worker_loans, worker_loan_payments,
worker_compensation_configs, commission_configs,
payroll_logs, payroll_bonuses, expenses, expense_categories
 
-- ⚠️ Demasiada fragmentación
-- ⚠️ Difícil de mantener consistencia

5. Appointments con demasiada lógica de negocio

-- 26 campos mezclando:
- Datos de cita ✅
- Datos de cliente guest (client_name, client_email, client_phone) ❌
- Features premium (promotion_id, waiting_list_id, location_id) ❌
- Category-specific (appointment_type, meeting_url, category_data) ❌

6. Falta Row-Level Security (RLS)

-- ❌ Multi-tenancy solo con scopes Laravel
-- ❌ Riesgo de data leaks si olvidas scope
-- ✅ Debería usar PostgreSQL RLS desde día 1

---

✅ Diseño Optimizado desde CERO

Principios del rediseño:

1. Single Responsibility: Cada tabla = 1 responsabilidad
2. Normalización: 3NF mínimo
3. RLS First: Seguridad a nivel DB
4. JSON solo cuando es flexible: No abusar de JSONB
5. Índices desde día 1: Performance crítica

🎯 Schema Optimizado (38 tablas core)

GRUPO 1: Core / Multi-Tenancy (4 tablas)

1. users (simplificado a 15 campos)

CREATE TABLE users (
    id BIGSERIAL PRIMARY KEY,
    email VARCHAR(255) UNIQUE NOT NULL,
    password VARCHAR(255) NOT NULL,
    name VARCHAR(255) NOT NULL,
    phone VARCHAR(50),

-- Índices
CREATE INDEX idx_users_email ON users(email);
CREATE INDEX idx_users_phone ON users(phone);

Campos removidos (movidos a otras tablas):

• two_factor_* → user_security table
• bio, preferences → user_profiles table (si realmente se necesita)

🎯 Ventajas del Diseño Optimizado

1. Simplicidad

• 38 tablas vs 65 (42% menos)
• Responsabilidades claras
• Fácil de entender para nuevos devs

2. Seguridad

• RLS en todas las tablas multi-tenant
• Imposible leakear datos entre teams
• Seguridad a nivel DB (no solo app)

3. Performance

• Índices desde día 1
• Queries optimizadas
• Full-text search nativo

4. Mantenibilidad

• Single Responsibility Principle
• Fácil agregar features (nuevas tablas, no nuevos campos)
• Migrations más limpias

5. Escalabilidad

• Tablas particionables (activity_logs por fecha)
• Sharding por team_id posible
• Queries predecibles

🚀 Plan de Migración (si decides refactorizar)

Opción A: Big Bang (riesgoso)

-- 1. Crear todas las tablas nuevas
-- 2. Migrar datos con scripts
-- 3. Cambiar código Laravel
-- 4. Deploy
-- ⚠️ Downtime: 2-4 horas
-- ⚠️ Riesgo: Alto

Opción B: Incremental (recomendado)

-- Fase 1: Crear tablas nuevas en paralelo
-- Fase 2: Dual write (escribir en ambas)
-- Fase 3: Migrar reads gradualmente
-- Fase 4: Eliminar tablas viejas
-- ✅ Downtime: 0
-- ✅ Riesgo: Bajo

Opción C: Fresh Start (solo si empiezas de 0)

-- Implementar schema optimizado directamente
-- ✅ Downtime: N/A
-- ✅ Riesgo: 0

---

📝 Recomendación Final

Si estás empezando DESDE CERO:

✅ USA el schema optimizado (38 tablas)

• Más simple
• Más seguro (RLS)
• Más mantenible
• Preparado para escala

Si ya tienes el sistema en producción:

⚠️ MANTÉN el schema actual

• Refactorizar = alto riesgo
• 65 tablas funcionan (aunque no sean perfectas)
• Mejor invertir tiempo en features

Solo refactoriza si:

• Tienes data leaks frecuentes
• Performance es crítico problema
• Vas a escalar a 10x+ usuarios
