NoSQL is a lie The document discusses different types of NoSQL databases like key-value, document, column, and graph databases. It explains the CAP theorem and tradeoffs between consistency, availability, and partition tolerance. Popular databases of each type are also mentioned, along with why each type may be used and what we've learned about NoSQL databases.
