+# Fase 2 — Procesamiento y Combinación por Año (Adicciones ↔ Violencia)
+
+Esta fase limpia y normaliza los datos cargados en PostgreSQL, elimina outliers y genera un **dataset combinado por año** listo para análisis avanzado.
+
+---
+
+## Ejecución
+
+1) Ajusta la conexión en el script si es necesario (host/puerto/DB).  
+2) Ejecuta el procesador:
+
+```bash
+python3 process.py
+```
+
+---
+
+## Descripción Técnica
+
+- Lectura de tablas desde **PostgreSQL**.
+- Normalización de columnas (incluye mapeo de \`año\` desde alias como \`a_o\`, \`anio\`, etc.).
+- Limpieza de valores vacíos y **eliminación de outliers (IQR)**.
+- **Resumen estadístico por dataset** (solo variables numéricas).
+- **Merge por \`año\`** para generar un dataset ancho (outer join).
+- Salidas en CSV para su uso en Fase 3.
+
+---
+
+## Requisitos
+
+Archivo \`requirements.txt\`:
+
+```txt
+pandas
+sqlalchemy
+psycopg2-binary
+numpy
+```
+
+Instalación rápida:
+
+```bash
+pip install -r requirements.txt
+```
+
+---
+
+## Salida
+
+- `resumen_estadistico_por_dataset.csv` — Descriptivos numéricos por tabla.  
+- `dataset_combinado_por_año.csv` — Dataset ancho fusionado por año (limpio y sin outliers).
+
+*Esta fase deja los datos listos para el análisis estadístico extensivo de la Fase 3.*
