Data security is paramount, especially when handling sensitive customer information like email addresses and purchase history. Here are some best practices:
1. Encryption: Encrypt sensitive data both at rest and in transit. 2. Access Control: Implement role-based access control to restrict who can access and modify the database. 3. Backups: Regularly back up your database to prevent data loss. 4. Compliance: Ensure your database design complies with data protection regulations like GDPR and CCPA.
