iPhone and iPad developers now have access to the market’s leading NoSQL database technology, and the only one providing native mobile-to-cloud data synchronization´╗┐

Mountain View, Calif. – May 2, 2011 – Couchbase, the NoSQL database company created via the recent merger of CouchOne and Membase, today announced immediate availability of a Mobile Couchbase for iOS beta release. Mobile Couchbase is powered by Apache CouchDB technology, invented by Couchbase CTO Damien Katz. Joining the Couchbase family of NoSQL data management solutions, Mobile Couchbase is the first NoSQL database available to native iOS application developers and the only one to provide transparent mobile-to-cloud data synchronization.

The O'Reilly MySQL Conference & Expo, returning April 11-14, 2011 to the Hyatt Santa Clara in Santa Clara, California, spreads the latest and best knowledge on MySQL and related technologies to the global open source community.

So why would a site dedicated to NoSQL news and information want to inform you of this conference? Because at this years conference there is a track on NoSQL technologies. The focus will be on how NoSQL can be used in conjunction with MySQL. Here are just a few of the tracks and speakers at the event.

MySQL's NoSQL Poll

MySQL is currently hosting a poll in which they have asked respondents to answer the following question:

Which open source NoSQL databases are you using?

While there is not enough of responses, currently at 112 at the time of writing, it's still interesting to see the responses. One note about the results is that multiple databases were allowed to be selected. Here are the current results, as of 3/22 at 10:45pm, of some of the various NoSQL databases.

Observations of MongoDB and CouchDB

Interesting article from the folks at Ocasta Labs. Ocasta Labs has been using CouchDB for over a year now. Recently a project popped up where they mention in their post that CouchDB did not seem like the right fit. The primary reason:

It turns out the reason it was the right choice was that Mongo is quite traditional. It relies on you having a middle tier where your app logic resides. Couch is more radical and it not only replaces the traditional database but also the middle tier. If, as we did on this particular project, you already have a middle tier then using Couch adds complexity to the solution.

Moving from CouchDB to Riak

Linkfluence has written a post discussing their decision to migrate away from CouchDB and to Riak. Why would they decide to move approximately 35 million documents and over 2 TB of data? According to their post three reasons:

  • Scalability
  • Versionning
  • Stability

In addition to discusses the issues they ran into with CouchDB they also discuss why they chose Riak and why they decided to enlist the assistance of Basho by obtaining a support contract.

BioGPS: A CouchDB Case Study

CouchDB, which is now Couchbase, has posted a CouchDB case study. This specific case study focuses on BioGPS. BioGPS is "an extensible and customizable gene annotation portal that is freely available to the biological research community". According to the case study, gene annotation data has a complex and heterogenous data structure. As a result CouchDB's key-document design was a "natural fit".

O'Reilly Webcast: CouchDB for .NET Developers

O'Reilly has another free webcast coming up on December 15th from 10-11am PT.

Here is the webcast description:

As .NET Developers, we are mostly accustomed to working with ADO.NET or ORM to access data in relational systems, where we map objects to columns and use SQL to query our data. In NoSQL and Document Databases things are different. Mappings and Queries are gone. Data is stored as is and retrieved via Map/Query functions.

What does that mean to a .NET Developer? How do we store and retrieve data? How do we query it? If you've been interested in document databases but do not know where to start, then this is definitely the webcast for you. We'll see what CouchDB is about and how to get your applications up and running using CouchDB and .NET in no time at all, and show you how creating and maintaining applications that use this NoSQL thing from a .NET Developers perspective is very simple.

PHP and CouchDB

Last week O'Reilly held another free webcast. The topic in this particular webcast was PHP and CouchDB and was presented by Benjamin Young. As always O'Reilly has released a video of the webcast that we've embedded in this post. Here is the official description from O'Reilly:

PHP developers generally use MySQL, but the rise of NoSQL databases has opened up new options for creating web apps. CouchDB's unique replication feature set and easy API make it a great fit for PHP developers looking to move into a NoSQL database. This talk will cover the basics of the CouchDB HTTP API and how to use it from PHP with and without helper libraries. We'll discuss some architecture approaches and briefly look at things to avoid when moving from an RDBMS to a Document Database such as CouchDB.

Scaling Out CouchDB with BigCouch

Here are the video and slides from the 10/22 O'Reilly webcast "Scaling Out CouchDB with BigCouch". Here is the description of the webcast pulled from the webcast page.

A common complaint raised by CouchDB skeptics is that "it doesn't scale," by which they mean it does not scale horizontally across many servers. This feature is necessary if CouchDB is to be used for Big Data problems. Cloudant has recently released BigCouch, its native horizontal scalability layer for CouchDB, as an open source project. BigCouch allows you to create clusters of CouchDBs that are distributed over an arbitrary number of servers. This talk will cover the basics of BigCouch, including deploying and managing your first CouchDB cluster, as well as some advanced features like quorum reads/writes and design patterns for distributed couchdb. Finally, for the erlang hackers out there, we'll discuss the internals of BigCouch, which will hopefully allow you to start contributing back to the project.
