Yesterday evening, the 9th BigData.be MeetUp was organised at the offices of NGDATA in Ghent. With 45 people showing up, this was our best attended MeetUp till know, illustrating the growing popularity of Big Data in Belgium. The meeting had a line-up of three presentations: Kenny Helsens, who presented a wrap-up of the zimmo.be project
Last week, Datablend open-sourced two new Tinkerpop Blueprints implementations: blueprints-mongodb-graph and blueprints-datomic-graph. Tinkerpop is an open source project that provides an entire stack of technologies within the Graph Database space. At the core of this stack is the Blueprints framework. Blueprints can be considered as the JDBC of Graph Databases. By providing a collection of
At the beginning of March, Rich Hickey and his team released Datomic. Datomic is a novel distributed database system designed to enable scalable, flexible and intelligent applications, running on next-generation cloud architectures. Its launch was surrounded with quite some buzz and skepticism, mainly related to its rather disruptive architectural proposal. Instead of trying to recapitulate
Storing massive amounts of data in a NoSQL data store is just one side of the Big Data equation. Being able to visualize your data in such a way that you can easily gain deeper insights, is where things really start to get interesting. Lately, I’ve been exploring various options for visualizing (directed) graphs, including
[information] Part 1 of this article describes the use of MongoDB to implement the computation of molecular similarities. Part 2 discusses the refactoring of this solution by making use of MongoDB’s build-in map-reduce functionality to improve overall performance. Part 3 finally, illustrates the use of the new MongoDB Aggregation Framework, which boosts performance beyond the
When I started running some years ago, I bought a Garmin Forerunner 405. It’s a nifty little device that tracks GPS coordinates while you are running. After a run, the device can be synchronized by uploading your data to the Garmin Connect website. Based upon the tracked time and GPS coordinates, the Garmin Connect website
Last week, the Neo4J plugin for Gephi was released. Gephi is an open-source visualization and manipulation tool that allows users to interactively browse and explore graphs. The graphs themselves can be loaded through a variety of file formats. Thanks to Martin Škurla, it is now possible to load and lazily explore graphs that are stored
NoSQL seems to be ready for prime time. Several NoSQL companies, including 10gen (MongoDB), DataStax (Cassandra) and Neo Technology (Neo4J), recently received millions in funding to expand their (commercial) NoSQL offerings. Even Oracle is now entering the already crowded NoSQL-space with its very own key-value NoSQL Database 11g. No doubt that this type of publicity
