beginnerNoSQL Fundamentals — CAP, BASE & Eventual Consistency
What is the CAP Theorem and why does it matter for NoSQL database selection?
CAP Theorem states that a distributed system can only guarantee two of three properties: Consistency (every read gets the latest write), Availability (every request gets a response), and Partition Tolerance (system works despite network partitions). Since network partitions are unavoidable, the real choice is CP vs AP. CP (MongoDB, HBase, Zookeeper): returns error if consistency can't be guarantee
