Ever since Facebook promoted its “graph search” methodology, lots of people in our industry have been waking up to the fact that graphs are über-cool. Thanks to the powerful query possibilities, people like Facebook, Twitter, LinkedIn, and let us not forget, Google have been providing us with some of the most amazing technologies. Specifically, the power of the “social network” is tempting

Over the past couple of months, I have been doing lots of "Intro to Graphs" talks across Europe. What started out as an idea in our London User Group, has now been a standard monthly introduction that has been extremely well attended. And that's not where it stops - many other people want to start doing these sessions as well in different cities. During these talks, lots of people have been

The latest M03 milestone release of Neo4j 2.0 is as you expected all about improvements to Cypher. This blog post also discusses some changes made in the last milestone (M02) which we didn’t fully cover. MERGE Cypher now contains a MERGE clause which is pretty big: It will be replacing CREATE UNIQUE as it also takes indexes and labels into accounts and can even be used for single node

What happened before As  you may remember, I created a little beer graph some time ago to experiment and have fun with beer, and graphs. And yes, I have been having LOTS of fun with it - using it to explain graph concepts to lots of not-so-technical folks, like myself. Many people liked it, and even more people had some questions about it - started thinking in graphs, basically. Which is way
