linearizability

monotonic atomic view

strengthens read committed by requiring that once a transaction observes another's effects, it observes all of them

monotonic reads

each process observes a monotonically advancing system view; once a write is observed, it remains visible

monotonic writes

if a single process performs two writes, all other processes observe them in that same order

read atomic

ensures atomic visibility of transaction updates; either all or none of a transaction's writes are observed

read committed

a consistency level that prohibits dirty writes, aborted reads, intermediate reads, and cyclic information flow

read uncommitted

one of the weakest consistency models; prohibits only dirty writes but permits dirty reads and other phenomena
