The CAP Theorem is a foundational concept in the world of distributed computing, particularly for databases. Developed by Eric Brewer, it challenges us to understand that in any network of databases, we can’t have the perfect combination of three key features at the same time: Consistency (all nodes show the same data), Availability (every request receives a response), and Partition Tolerance (the system continues to operate despite network failures).

Understanding Each Aspect of CAP

1. Consistency

This is about having the same data across all system parts at any given time.
