Types of databases

• Relational Databases: Use tables to store data and relationships between data (e.g., MySQL, PostgreSQL).
• NoSQL Databases: Designed for more flexible data models and often used for big data or real-time web applications (e.g., MongoDB).
• Graph Databases: Store data in nodes and edges to represent relationships (e.g., Neo4j).
• Vector Databases: Used in ML to store data in the form of embeddings

Today we’ll be learning about MongoDB which is a NoSQL Database
