Welcome to the Database Management tutorial! Whether you're new to databases or looking to deepen your understanding, this guide will cover essential concepts and practices. Let's dive in!

🔍 What is a Database?

A database is an organized collection of data stored in a structured format. It allows for efficient retrieval, management, and updating of information. Common types include:

  • NoSQL Databases (e.g., MongoDB, Redis)
  • Graph Databases (e.g., Neo4j)
