+
+## Orden de Ejecucion
+
+1. Ejecutar DDL de erp-core primero (schemas base)
+2. Ejecutar archivos de este directorio en orden numerico
+
+## Convencion de Nombres
+
+- Tablas: snake_case, plural (ej: `ordenes_transporte`)
+- Indices: `idx_{tabla}_{columnas}`
+- Foreign Keys: `fk_{tabla}_{referencia}`
+- Constraints: `chk_{tabla}_{regla}`
+
+## Multi-Tenancy
+
+Todas las tablas incluyen:
+- `tenant_id UUID NOT NULL`
+- Indice compuesto con tenant_id
+- RLS policy para aislamiento
+
+## Ejemplo de Tabla
+
+```sql
+CREATE TABLE transport.ordenes_transporte (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  tenant_id UUID NOT NULL REFERENCES public.tenants(id),
+  codigo VARCHAR(50) NOT NULL,
+  -- ... mas columnas
+  created_at TIMESTAMPTZ DEFAULT NOW(),
+  updated_at TIMESTAMPTZ DEFAULT NOW(),
+  created_by_id UUID NOT NULL,
+  CONSTRAINT uq_ot_tenant_codigo UNIQUE (tenant_id, codigo)
+);
+
+CREATE INDEX idx_ot_tenant ON transport.ordenes_transporte(tenant_id);
+CREATE INDEX idx_ot_estado ON transport.ordenes_transporte(tenant_id, estado);
+
+ALTER TABLE transport.ordenes_transporte ENABLE ROW LEVEL SECURITY;
+
+CREATE POLICY tenant_isolation ON transport.ordenes_transporte
+  USING (tenant_id = current_setting('app.tenant_id')::uuid);
+```
