It’s time to begin the coding of my SOA entity service with NoSQL project, and as promised I’m starting with the web service’s contract.
I want to build the entity service by using as little Java code as possible but at the same time preserve the contract-first approach.
Chris Harris and Alvin Richards present "MongoDB in Production." Chris Harris is European Solution Architect at 10gen and Alvin Richards is the Senior Director, Enterprise Engineering at 10gen.
We must only answer the question is BFS the best algorithm that finds the shortest path between any two nodes of the graph?
My Sunday reading session was on a couple of great NoSQL blog posts that are definitely worth reading.
Using Spring Data Neo4j it was incredibly easy to model and import the Hubway Challenge dataset into a Neo4j graph database, to make it available for advanced querying and visualization.
I am happy to announce the latest version of Dex, MongoLab’s Index Bot. With version 0.5, we’re declaring Dex halfway-there in terms of major features.
In this article, I will help you quickly write Geospatial queries described in the following presentation using Java. I assume you have MongoDB server up and running on your machine.
Continuing to discover the powerful set of Redis features, the one worth mentioning about is out of the box support of pub/sub messaging.
I created a sample project and put it out on github. Let me know if you have any trouble.
In this first edition of a new weekly post, we will revisit the past week to make sure you are completely up-to-date in the world of NoSQL.
How do you create the best index for a complex MongoDB query? I'll present a method specifically for queries that combine equality tests, sorts, and range filters, and demonstrate the best order for fields in a compound index.
Last month I presented a webinar introducing the basics of application development using VoltDB. We had a lot of great questions and I thought it would be handy to write them up and share the answers with everyone.
Since with graphs we can represent real-life problems it’s almost clear why we would need an efficient algorithm that calculates the shortest path between two vertices.
Probably the closest database object-relationally to Postgres is Informix. Informix in fact got its object-relational approach with the purchase of Illustra, a Postgres fork.
I was working on a section on the gooey innards of journaling for The Definitive Guide, but then I realized it’s an implementation detail that most people won’t care about. However, I had all of these nice diagrams just laying around.
backbone.cloudant is a small library we've developed to make connecting to Cloudant from Backbone applications really easy.
When dealing with a large text dataset, most folks jump right into NLP and semantic analysis, it’s interesting to learn when that’s not such a good idea.
Next up, after GitHub and Bootstrap, in the session I presented last month during a company trip, is MongoDB.
Here are some of the amazing geo-social visualizations you get when you compare two projects:
If you're using the @MapResult way in your Neo4j repositories, be careful of what you use in the corresponding @ResultColumn annotations.
In this post I am going to review Pramod J. Sadalage and Martin Fowler's new book entitled "NoSQL Distilled - A Brief Guide to the Emerging World of Polyglot Persistence."
Available immediately, Neo4j 1.8 offers a delightful experience for reading and writing graph data with the simple expressiveness of the Cypher language.
My name is Kaz, and I am the CTO of Treasure Data. Recently, I gave a presentation at MongoDB Silicon Valley User Group titled “Fluentd loves MongoDB."
Last week marked the end of the MYOB Neo4J coding competition. This was an internal competition for the development team in the Accountants Division of MYOB
