What Does Database Do :

Databases store, manage, and organize data efficiently. In web development, they help store user information, content, and any dynamic data the website needs. DBMS can be broadly categorized into SQL and NoSQL systems.

How Databases Work with Web Development :

Databases are the backbone of modern web applications. They store, retrieve, and manage user and system data efficiently. In web development, databases are essential for dynamic websites and apps that require login systems, content updates, and user interaction.

Why Use a Database?
  • Persistent data storage (users, posts, orders, etc.)
  • User authentication and session handling
  • Manage structured (SQL) and flexible (NoSQL) data formats
Connecting Web to DBMS
  • Frontend (HTML/JS) → API → Backend (Node.js, Python)
  • Backend → DB via libraries (e.g., Sequelize, Mongoose)
  • Data is retrieved → processed → displayed to user
