How to tell if your data would benefit from a different database
Introduction
Heard of graph databases but not exactly sure what they are? Or maybe you have but you’re not quite sure where they apply. You’re in the right place, we’re going to be looking at both in this post, and by the end of it, hopefully you’ll have those creative graph juices flowing! You can also check out this webinar after.
So what is a graph?
Originating from a branch of mathematics, a graph is a set of discrete objects, each of which may have a set of relationships with other objects. Graph theory has many important applications, such as route planning, finding dependencies and managing…
Want to dabble in graphs with family and friends? Not quite sure where to start? How about a quick and dirty trick using Google Forms, Google Sheets and a Neo4j Sandbox?
Where Do I Start?
So you’ve heard about graphs, they sound like fun! Now, you’re wondering where to start. Maybe you’ve had a go with one use cases in the Neo4j Sandbox, but now you want to create some data. Perhaps you’re not feeling too confident about generating or importing large data sets just yet. Or are you seeking that graph-based ice breaker to show off your new skills?
I have a treat…
Explore your enterprise architecture assets with Neo4j. *Republished to Medium with updates for GDS*
There is a lot of potential benefit in importing and interrogating your enterprise architecture components in a graph database; you can easily do extensive analysis on dependencies, redundancies, what-if and root cause analysis. ArchiMate is a commonly-used framework for representing different architectures; it is well-defined and used by many organisations and templates are available in many diagramming packages.
There are a number of great blogs showing the power of doing just this in Neo4j, such as:
- Michael Herman’s blogs on importing and querying ArchiMate models in…

The write-up of the second part of our modelling and data loading revisit, we explore how asking new questions changes the data model.
Overview
Here’s another super quick write-up of the second session we did on Twitch. Again, it’s a leisurely step through for those of you who want to visit this at your own pace. If you want a reminder of the first, part, check out the write up here.
Here’s the second stream, if you want to re-watch it for posterity (and observe how I’ve moved around in my study yet again!):

The latest version of Neo4j Bloom is out. Let’s a look at the new features and improvements
The latest version of Neo4j Bloom, 1.5, came out this month. In this release, we see some exciting new features, as well as improvements to functionality and performance. Let’s check them out!
New Features
The latest new features are:
- A mini map for the scene.
- New style rule to uniquely color nodes in a category based on distinct property values.
- Choice of sampling data when generating or refreshing the perspective.
Let’s have a look at the mini map and the new style rule a bit more detail.
For this, I will be using the Northwind graph, available from Neo4j Browser. …

What’s a Neo4j sandbox?
The Neo4j sandboxes are a great way to experiment and work with Neo4j without needing to download, install and configure the database. We have a broad range of use-cases with preloaded datasets and a step-by-step guides to get you going, as well as blank sandboxes to import and work with your own data.
A sandbox lasts for three days, but can be extended to a maximum of 10 days. You’ll also find handy code snippets in various languages to connect to the sandbox from your favourite stack.
So what is THIS sandbox all about?
