Kinda begging the question aren't we? I turn to nosql for things that aren't key-value, generally.

  What do you mean? Isn't NoSQL inherently key-value?

    Are graph databases key/value? Are document databases key/value? Try this: https://en.wikipedia.org/wiki/NoSQL#Types_and_examples_of_NoSQL_databases https://en.wikipedia.org/wiki/NoSQL#Types_and_examples_of_No... https://www.youtube.com/watch?v=qI_g07C_Q5I https://www.youtube.com/watch?v=qI_g07C_Q5I

    No. Triplestores and Graph databases aren't key-value stores. There's more to NOSQL than key value stores although most examples seem to be.

    All structured data can be represented as key-value, that includes SQL. They just differ in what constraints are used for the keys and values. As for your question, NoSQL datastores can be grouped into multiple categories: - column stores (like hadoop, cassandra, informix), which optimize for sharded and distributed storage of related data elements - document stores (like elasticsearch), which focus on metadata organization for large opaque (binary) objects - key-value stores (like redis, openldap), which are basically unstructured, associative arrays (hash maps). They allow the most storage freedom, and are hardest to optimize. - graph databases (like neo4j, trinity), where more information is carried in annotated inter-object links than in the objects themselves.
