Dear Reader,

Deepak Vohra has published three NoSQL books. 
Please have a look if they could be of interest for you!

NoSQL Web Development with Apache Cassandra

Apache Cassandra is the most commonly used NoSQL database written in Java and is renowned in the industry as the only NoSQL solution that can accommodate the complex requirements of today’s modern line-of-business applications. Cassandra is the technology of choice for such data-driven organizations as Netflix, eBay, Constant Contact, Comcast, and scores of others. In NOSQL WEB DEVELOPMENT WITH APACHE CASSANDRA, you will learn about all aspects of using Cassandra in web applications--including accessing the Cassandra database using the common programming/scripting languages Java, PHP, Ruby, and JavaScript. Master web development using Apache Cassandra with the help of NOSQL WEB DEVELOPMENT WITH APACHE CASSANDRA. - See more at:

Pro Couchbase Development

Welcome GPUdb!

Just inserted a new DB:

Welcome GPUDB!


 A distributed database for many core devices. GPUdb leverages many core devices such as NVIDIA GPUs to provide an unparallelled parallel database experience. GPUdb is a scalable, distributed database with SQL-style query capability, capable of storing Big Data. Developers using the GPUdb API add data, and query the data with operations like select, group by, and join. GPUdb includes many operations not available in other "cloud database" offerings.

Good luck! (thx MB for pointing me to this DB)
