# Data Validation Engine

## Overview

Implement and enforce data integrity rules at the database level using CHECK constraints, triggers, foreign keys, and custom validation functions across PostgreSQL and MySQL.

## Prerequisites

- Database credentials with ALTER TABLE and CREATE FUNCTION permissions
- `psql` or `mysql` CLI for executing validation queries
- Current schema documentation or access to `information_schema` for column specifications
- Business rules document describing valid data ranges, formats, and relationships
- Backup of production data before applying new constraints (constraints may reject existing invalid data)
