FASE 6: Plan Refinado - ERP Construcción

Proyecto: erp-construccion Fecha: 2026-01-04 Estado: Completado Base: FASE-5-ANALISIS-DEPENDENCIAS.md

---

1. Ajustes al Plan Original

1.1 Cambios Incorporados

#	Cambio	Razón
1	proyecto_id → fraccionamiento_id	No existe tabla proyectos
2	projects.collaborators → construction.colaboradores_obra	Adaptación al giro
3	FKs opcionales a Core	Permitir instalación independiente
4	Trigger adaptado	Usar avances_obra en lugar de partidas
5	Orden de ejecución revisado	Respetar dependencias

1.2 Archivos Finales

Archivo	Acción	Contenido
08-financial-ext-schema-ddl.sql	Crear	5 tablas, 2 ENUMs
09-projects-ext-schema-ddl.sql	Crear	3 tablas, 2 funciones (adaptado)
02-hr-schema-ddl.sql	Modificar	+11 tablas, +3 ENUMs
06-inventory-ext-schema-ddl.sql	Modificar	+5 tablas
07-purchase-ext-schema-ddl.sql	Modificar	+1 tabla, +1 función
migrations/20260104_fase8.sql	Crear	Migración consolidada
seeds/*.sql	Crear	4 archivos seed
