Normalized SQL Database Schema Design

Relational database tables designed to store rules, checks, reports, and historic audit trends.

CREATE TABLE categories (
  id INT PRIMARY KEY AUTO_INCREMENT,
  name VARCHAR(50) NOT NULL,
  description TEXT
);

CREATE TABLE rules (
  rule_id VARCHAR(30) PRIMARY KEY,
  name VARCHAR(100) NOT NULL,
  category_id INT FOREIGN KEY REFERENCES categories(id),
  severity VARCHAR(15) CHECK (severity IN ('CRITICAL', 'WARNING', 'INFO')),
  docs_url VARCHAR(255) NOT NULL,
  expected_result TEXT,
  correction_guide TEXT
);

CREATE TABLE audits (
  id INT PRIMARY KEY AUTO_INCREMENT,
  url VARCHAR(255),
  html_payload TEXT,
  score_percentage INT,
  run_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE audit_results (
  audit_id INT FOREIGN KEY REFERENCES audits(id),
  rule_id VARCHAR(30) FOREIGN KEY REFERENCES rules(rule_id),
  status VARCHAR(10) CHECK (status IN ('PASS', 'WARN', 'FAIL')),
  actual_found TEXT,
  PRIMARY KEY (audit_id, rule_id)
);
