No Sql Databases

I came across these databases:

1. Synchronized distributed cloud database https://www.firebase.com/how-it-works.html

2. http://www.datomic.com/

3. Druid: http://www.github.com/metamx/druid

One Druid cluster currently exposes a data set of >40 billion rows of data representing >2 trillion impressions in hypercubes of varying dimensionality (largest is 30+ dimensions) while allowing for exploration using top lists and timeseries in sub-second latencies

NoSql World

some of the interesting developments in the NoSQL arena.

Firstly this article gives you a better understanding of the various types of NoSql databases that are available

This website gives you comprehensive information related to Nosql database available in the market: http://nosql-database.org/

Case Studies

Some of the interesting large database implementations like Google, Facebook, reddit.com, twitter, Amazon use one or the other form Object/document databases along with relational databases

Doug you might be interested to read this: http://www.quora.com/Why-does-Quora-use-MySQL-as-the-data-store-instead-of-NoSQLs-such-as-Cassandra-MongoDB-CouchDB-etc

 

Microsoft/ .net based doc databases

  1. Microsoft Research is working on Trinity and they a Linqified querying  of data from the data store
    http://research.microsoft.com/en-us/projects/trinity/

http://www.infoq.com/news/2011/04/Trinity

  1. Another one is Raven DB it’s a document database created by a .net developer/Architect which is based on Couch DB architecture.

The author is one of the contributor to nHibernate and a leading speaker, trainer, blogger, etc.

And here you can find a ton of blog posts regarding Raven db : http://ayende.com/Blog/category/564.aspx
