My recent blog post about Stonebraker’s talk at the EPFL (host university to Prof. Martin Odersky, creator of the Scala Language and Co-Founder of Typesafe) has triggered a very interesting discussion.
At Pearson, the OpenClass domain model is extended into a programmatic construct, a DSL based on Gremlin, which abstracts away the language of the graph.
10gen, the core company behind MongoDB development, has officially changed its name this week to MongoDB, Inc. The company has gained significant venture capital investments over the past few years and they still retain many elite programmers along with the MongoDB creators.
I recently finished the 1st week of the 10gen MongoDB intro course in under 5 hours, which included listening to lectures, answering quizzes and submitting my homework, plus some other stuff I wanted to try out.
It's my pleasure to announce that Bernie Hackett and I have released PyMongo 2.6, the successor to PyMongo 2.5.2, with new features and bugfixes.
Basho developer, Adron Hall has just released his Riak interface application for Windows 8, which he has named "Junction."
The specialists at CX Security recently reported a 'severe'-labelled exploit for the HBase NoSQL data store. The only solution is to make plans to upgrade as quickly as possible to version 0.92.3 when it is released, or upgrade to 0.94.9 or later.
This slideshow should give you some nice, quick illustrations for understanding the data structures of Riak and its advantages.
Pretty easy to install and get going // I use a Mac and hence I had to use some manual steps, but I had the mongo db and shell up and running in about 10 minutes (download time included)
Hybrid persistence works fine for caching. But whenever your data is split into multiple sources in way that you’d have to combine the parts from each, it’s not gonna be fun time. Just so you know.
As you might have heard, FoundationDB became publicly available last week. As we’ve discussed in the past, we’re very excited here at OpenSource Connections about this emerging database.
"We are not modelling reality, but the way information about reality is processed, by people." This is advice that is helpful when designing a model in a graph database.
MongoHQ wrote a helpful blog on the encryption features in MongoDB. Its a big deal for the larger, more cautious companies as well as smaller ones, so it behooves a MongoDB host in company like MongoHQ to help share information about MongoDB's security.
It's clear that session storage is a super-popular use case for the Redis NoSQL data store. I found another example this week by Armin Ronacher who writes about his coding excursions with the Flask Python micro framework.
Get an introduction to the current status of Apache Cassandra and a recap of what's coming in the next major 2.0 release.
This week, Karl Matthais, an engineer at MyDrive, posted an article about their switch from MongoDB to Cassandra along with some stats showing significant performance improvements.
NewSQL database Datomic is tailored for the Clojure community, but using a gem called Diametric, Ruby programmers can use Datomic as well via Rails.
This blog post features a small demo project on github: neo4j-uuid and explains how to automatically assign UUIDs to nodes and relationships in Neo4j. A very brief introduction into Neo4j 1.9′s KernelExtensionFactory is included as well.
The data obtained for an OWL ontology is then stored in a knowledge base from which it can be retrieved using SPARQL queries. But if it's all already there, what's the point of combining it with a graph database?
We have exciting product news to share: the Couchbase-ElasticSearch plug-in version 1.1.0 has now been released.
After working with Apache Jackrabbit for a while, I still wonder about the database persistence managers that Jackrabbit provides. Storing the node serialized in a blob always seemed a bit perverse when using the concepts of a database.
After the Boston bombings, this interview talks about why unstructured information is important and how search is redefining how intelligence agencies in particular can benefit from NoSQL and MarkLogic in particular.
You can find a surprising number of entertaining or intriguing things in online software documentation. It seems that ZeroMQ isn't the only open source project with a little humor injected into the docs.
The graph squad at Spotify has been tasked with creating the best music graph in the world. Organizing musical data is a perfect use case for a graph database, and Spotify is experimenting with Neo4j, Giraph and Titan
Here's a video you ought to see. It has leaders from several competing NoSQL companies agreeing on at least one thing: People need to embrace NoSQL.
