Quest unveils NoSQL database management tool





From the webpage:

Membase is an open-source (Apache 2.0 license) distributed, key-value database management system optimized for storing data behind interactive web applications. These applications must service many concurrent users; creating, storing, retrieving, aggregating, manipulating and presenting data in real-time. Supporting these requirements, membase processes data operations with quasi-deterministic low latency and high sustained throughput.

NoSQL @ Qbranch

(slides by) Marten Gustafson


Twitter unveils FlockDB

A new database on the scene?!


Look also on the first link of this post:

Michael Stonebrakers views of the world

In the recent ACM Magazine Michael Stonebraker writes in the abstract
for a SQL Databases vs. NoSQL Databases:

"Recently, there has been a lot of buzz about NoSQL databases. In fact, there were at least two conferences on the topic in 2009, one on each coast."

Well I may be to sentitive here but the world does not only consist of the
US-West- and the US-East Coast.

If you look at the event registry on http://nosql-database.org
you can easily see that there had been 8 events! Of course some have not
been 'real' conferences and Michael says "at least" so he is on the safe side.

But we definetely had more then two conferences and I would be happy if events
outside the US would be mentioned in the future. Especially Berlin (2009 and 2010) or London in these days. In total I count 19 events!

So keep on fighing for choice, diversity and real data / requirements analysis!

NoSQL databases

Really good slides!

MapReduce in Simple Terms

Take this...
IT can be so simple.


what a difference if you compare this to the text in the Ullmann

Can't wait for NoSQL to Die

Some good points not to overestimate NoSQL because of the data size you have to manage...


However he is missing the point that NoSQL can be a good usecase even if you have only
MBs of data...
The problem is always reduction of facts. The data and database landscape is too complicated to reduce it into a few statements. That's why we are working on some orientation texts...

High Performance Scalable Datastore Comparison


(well done Rick and greetings)

Added Versant ODBMS

to Soft NoSQL:

Versant: Languages/Protocol: Java, C#, C++, Python. Schema: language class model (easy changable). Modes: always consistent and eventually consistent Replication: synchronous fault tolerant and peer to peer asynchronous. Concurrency: optimistic and object based locks. Scaling: can add physical nodes on fly for scale out/in and migrate objects between nodes without impact to application code. Misc: MapReduce via parallel SQL like query across logical database groupings

Is NoSQL Finally Going Mainstream?


New improvements on website

1. I have changed the layout of http://nosql-database.org a little.

2. I made two categories: Core NoSql and Soft NoSQL
(any better idea?)

3. I added an XML section because Mark Logic seemed to have lots of NoSQL features.

Great Overview. Gave it a star.

Alternative Blogs

Dear Reader,

before I start posting the changes, two more remarks:




will provide more messages! And they are also great resource about NoSQL.

However this blog and http://nosql-databases.org do target mostly overview articles and some interesting stuff.
So perhaps fewer but more consise.

Stefan Edlich

nosql-database.org Blog RSS starts!

Dear Readers,

this Blog / RSS mirrors all changes of the popular website

We will reduce Product News here but instead we will have
all conceptional articles about NoSQL here and in the website.

I hope you enjoy this service here and on the webite

I would be happy if you get in touch with me with any ideas you have!

One last remark:
There will be the second NoSQL Event / Meetup in Germany embedded
inside ICOODB. Please follow the two links:

* http://nosqlfrankfurt.de
* http://icoodb.org

Best Regards and keep on inventing!
