SQL vs NoSQL: SQL enforces schema and ACID, NoSQL offers flexibility and horizontal scaling

Ever wondered how databases handle massive data across the globe?

Imagine you're planning a worldwide concert tour, needing to sync ticket sales and show times across continents.

A distributed SQL database acts like a global coordinator, ensuring everyone sees the same concert details, even if they're in different countries. It's like having a universal clock that everyone follows.

Example

If one city sells out, the database instantly updates ticket availability worldwide.

Remember this

It's all about real-time, consistent data sharing across vast distances.
