This talk was from the Canberra Java User Group in July 2010. You can download the source to go with these slides from http://bitbucket.org/glen_a_smith/cjug-nosql-examples.
The NoSQL (Not Only SQL) movement has been gaining a lot of press over the last year as a means of scaling massive data storage, complex relationships and lightening fast retrieval for the Web's biggest sites. This month we're taking a trip to the big end of town and looking at some of the backend technologies that are powering sites like Twitter, Facebook, LinkedIn, Reddit, Digg and Google.
We'll be looking at popular Java clients and servers that play in the NoSQL space and have a brief survey of the following popular NoSQL platforms: Document Databases (CouchDB), Sophisticated Key/Value Stores (Voldemort), Graph Databases (Neo4j), and simple Key/Value stores (Memcached). It'l be a lightening tour of what each technology offers, some source code on how it works, and lots of headshifts about how to store data such that you don't ever need another Left Outer Join!
Clipping is a handy way to collect important slides you want to go back to later.
