CAP theorem: History, Explanation & Overview

In database theory, the CAP theorem, also named Brewer's theorem after computer scientist Eric Brewer, states that any distributed data store can provide at most two of the following three guarantees:

CAP theorem relationships Subject–Predicate–Object triples

TTTA extracted 28 structured relationships around CAP theorem. Examples in this analysis include RDBMS choose consistency over availability → instance of → both availability and consistency can be satisfied.Database systems designed with traditional ACID guarantees in mind and geographic sharding to maintain availability of data owned by the queried node → instance of → consistent shared-nothing architectures may use techniques. The table shows each extracted connection, where it came from and its confidence.
