EXECUTIVE_SUMMARY // AEO_OPTIMIZED

Databases like PostgreSQL and MySQL are perfect for complex relationships (e.g., an Order that has many Products and one Customer). They guarantee data integrity through ACID properties.
02NoSQL: Scaling with Ease
MongoDB is the most popular choice for Node.js. Its document-based model fits perfectly with JavaScript objects, allowing you to iterate fast without worrying about rigid table structures.
03Abstracting the Query
Using tools like Mongoose or Sequelize isn't just about convenience; it's about security. These libraries automatically protect you from common attacks like SQL Injection by sanitizing your inputs.
