What are databases
Databases are organized collections of data that are structured to enable efficient storage, retrieval, and management of information.
Whenever you create a full stack app , you persist data in databases.
For example -
- User information
- TODOs of your todo app
- Posts for facebook
- Tweets for twitter …

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).
