Find out what's new in the Neo4j world

Modelling and querying time-based events in a graph is a fairly common discussion topic and a frequently asked question on Q/A sites. In this blog post, we evaluate some of the common approaches and introduce GraphAware TimeTree, a GraphAware Framework Module that simplifies modelling time and events in Neo4j.

In the first part of this short series about random graph models, we talked about why they are useful and had a brief look at two of them: Erdos-Renyi graphs and Barabasi-Albert model. In this post, we take a look at the “small world” phenomenon and another network model, namely the Watts-Strogatz model.

With MERGE set to replace CREATE UNIQUE at some time, the behavior of MERGE can sometimes be tricky to understand.

Efficient counting of relationships in Neo4j was the cornerstone of my Master Thesis and the reason the very first GraphAware Framework module called the Relationship Count Module was born. The improvements in Neo4j 2.1 around dense nodes and the addition of getDegree(…) methods on the Node interface made me eager to do some benchmarking around relationship counts again.

When one obtains a graph data from a measurement on a real world network, it is sometimes useful to make comparison with a random graph. Such graph is characterised by certain degree distribution, which you can imagine to be a list of degrees of nodes present in the network. The most interesting distributions have certain functional dependence which allows one to infer what processes are dominant in formation of the network. The processes consequently characterise the relationships between the nodes.

One of the main goals of the GraphAware Framework is to simplify and speed up development with Neo4j. Although it is called a “framework” for reasons explained elsewhere, today we will simply treat it as a library of useful, tested, and documented Java code. The feature we will introduce is called Improved Transaction Event API, which is exactly what it says on the tin.

A couple of days ago, I wrote about unit testing with GraphUnit. GraphUnit tested the state of an embedded Neo4j database. What if you run Neo4j in standalone server mode? Fortunately, you can still test it and match subgraphs using the GraphAware Neo4j RestTest library.

Testing the state of an Embedded Neo4j database is now much easier if you use GraphUnit, a component of the GraphAware Neo4j Framework.

Today, it is exactly one year ago since Graph Aware Limited was incorporated. It started as a one man show, whilst I was finishing my MSc. Thesis at Imperial College London. Since then, we’ve been growing slowly but steadily and will be moving to our new London office fairly soon (announcements to come). We have happy clients in London, New York, Copenhagen, Barcelona, Prague, and Accra.

Recently, we announced the GraphAware Framework. Today, I would like to introduce its first feature called GraphUnit. GraphUnit is a component that helps Java developers unit test their code that talks to Neo4j and mutates data.
