CORE DEFINITION

Linearizability, also known as atomic consistency or strict consistency, refers to a model in distributed systems and concurrent programming that ensures all operations appear to take effect instantaneously at some point between their invocation and response, and that the overall order of operations respects a global real-time ordering, as if a single-core processor were handling all requests.

Anchor fast decisions

Database transactions guarantee atomicity (the 'A' in ACID) to ensure operations are indivisible: either all changes are committed or all are rolled back, avoiding the system being left in a partially completed intermediate state that could cause data corruption.
