Presentation: NoSQL @ CodeMash - An Interesting NoSQL Categorization

A generic intro to NoSQL by Ben Scofield.

The slides go quickly (as it’s normal for an intro presentation) through probably the most representative NoSQL solutions: Redis, Tokyo Cabinet, Cassandra, CouchDB, MongoDB, Riak, Neo4j.

What I have found more interesting is the following categorization:

  Performance Scalability Flexibility Complexity Functionality
Key-Value stores high high high none variable (none)
Column stores high high moderate low minimal
Document stores high variable (high) high low variable (low)
Graph databases variable variable high high graph theory
Relational databases variable variable low moderate relational algebra

Another way to look at the above categorization is in this slide from the (awesome) presentation on graphs and Neo4j by Emil Eifrem
