The Graph Technology Landscape Graph

Our friends at Graphaware, and specifically Janos Szendi-Varga created a fantastic overview of the Graph Technology Landscape in 2019. It's actually pretty cool:
There's lots of interesting data in there, which Janos put into a CSV file over here. I thought that was really cool, and took the data for a spin in a Google Sheet, and then modified it a little bit from there.

Next thing for me was to create a

Which I have now made available as an import script and a graphgist over here. You can explore the data in the deployed graphgist yourself, and figure out some of the hidden and not-so-hidden connections in the Graph Technology Landscape. 

Hope you will have as much fun with this as I had.

Cheers

Podcast Interview with Jess Mason and Jason Cox, Untiltled Folder

Yeah,  I think I am going to repeat myself. Another podcast that was long overdue waiting to be published. I interviewed my next guests middle of December 2018, and it's hard to believe that I only just MADE the time to publish the episode. My bad - again. It's another great chat though - so you should still listen and look at some of the very cool links included below - you will not regret it. Jess and Jason are doing some amazing stuff with Neo4j over in Philly, and check it out. Here it goes:



Here's the transcript of our conversation:
RVB: 00:00:26.434 Hello, everyone. My name is Rik, Rik Van Bruggen from Neo4j, and here I am, again, recording another Neo4j Graph Database Graphistania Podcast. And tonight I am joined by two guys from Philadelphia in the USA that have been doing some amazing work with Neo4j. And on top of that, they have the funniest company name, I think at least. It's called Untitled Folder. That's Jess and Jason. Jess and Jason, welcome to the podcast.

JM: 00:01:04.071 Hi. Thanks for having us on the podcast.

JC: 00:01:04.525 Hello.

Podcast Interview with Emil Eifrem, Neo4j

We've been around the block a few times in this podcast. It has been a fantastic experience to develop this thing from a crazy idea at a booth at Qcon (thanks again, Michael!) into something that has really gained a life of its own. I for one still enjoy making them time after time - I hope they are a good listen/read as well.

As part of that journey,  I have course also interviewed our "Fearless Leader" and "Chief Instigator", aka Emil Eifrem, a few times. We talked in summer of 2015, and then again around this time of the year in 2016 -  and swore expensive oaths not to let another episode be too long after. And we failed miserably. So it felt right to do a longer, more elaborate episode now, which we actually published with video on Youtube too:


Of course the Podcast feed and Soundcloud have the same show episode too:

Here's the transcript of our conversation:
RVB:   00:00:54.475 Hello, everyone. My name is Rik, Rik Van Bruggen, from Neo4j and here I am recording another podcast episode. And I think the other person on the other side of this call is going to agree that it's been way too long.

Podcast Interview with JEP, the Graph Database

Alright - here's something special for you. For the past couple of days, I have been listening to - no, I have been DEVOURING all the episodes published in the "Everything is alive" podcast series published by Radiotopia. It is such a great show. Funny, interesting, sad, thoughtful, and ... inspirational. Because - what would happen IF EVERYTHING WAS ALIVE??? I could not not think about that - and specifically, I thought about Neo4j instances... what if THEY were alive? What if I could interview a real, live Neo4j instance - what would that be like???

I decided to find out. Here's my lovely chat with imaginary JEP, the Graph Database. Turned out to be a fine chap, really. Here it goes:


Here's the transcript of our conversation:
RVB: Good morning everyone, my name is Rik, Rik Van Bruggen from Neo4j - and today I am doing a really special episode of the Graphistania podcast series. It's an episode that I got the inspiration for by listening to Everything is Alive, a podcast hosted by RadioTopia. They did some amazing work interviewing some of the most interesting characters ever - and I would love to continue that tradition here today on Graphistania.

Podcast interview with Will Lyon, Neo4j

Been a while since I have been able to publish more podcast episodes - sorry about that. Will try to keep up a regular pace - but no guarantees. However, I must say that the conversation that I had with my colleague Will Lyon made me think that I really should keep it up... the Neo4j ecosystem, and company is full of people with lots of interesting things to say - and talking to them is just a blast.

So this conversation was long overdue, because Will has done SO MUCH for the Neo4j Community in the past couple of years - it's pretty crazy. How do you start a conversation like that? Turns out it's really easy. So nice. Listen to it over here:

Here's the transcript of our conversation:
RVB: 00:00:00.615 Hello, everyone. My name is Rik Van Bruggen from Neo4j, and tonight I have a very long overdue guess on this podcast episode. Someone that I've been dying to talk to, actually, for quite sometime because he's done such an amazing job in the Neo4j community over the past couple of years. And that's my colleague, Will Lyon. Hi, Will.

Working with the ICIJ Medical Devices dataset in Neo4j

Just last weekend our friends at the ICIJ published another really interesting case of investigative journalism - tracking down and publishing the quite absurd and disturbing practices of the medical devices industry. The entire case with all of the developing stories can be found at https://medicaldevices.icij.org/ - take a look as it really is quite fascinating. Of course that meant that I wanted to see what that data looked like in Neo4j, and if I could have a play. I didn't have time for a full detailed exploration yet - but hopefully this will also give others the opportunity to chime in. So let's see.

The Medical Devices dataset as a graph

This turned out to be surprisingly easy. Just download the Zip file from the ICIJ website: https://medicaldevices.icij.org/download/icij-imddb-2018-11-25.zip, unzip this, and then we get 3 comma-separated-values files:
  • one for the Devices that are being reported on
  • one for the Events that are being reported (whenever something happens to a device (eg. a recall) then that is logged and reported)
  • one for the Manufacturers of the medical devices.
That's easy enough.

Data Lineage in Neo4j - an elaborate experiment

For the past couple of years, I have had a LOT of conversations with users and customers of Neo4j that have been looking at graph databases for solving Data Lineage problems. Now, at first, that seemed like a really fancy new word used only by hipster technovangelists to try to appear interesting, but once I drilled into it, I found that it’s actually something really interesting and a really cool application of graph databases. Read more on the background of it on wikipedia (as always), or just live with this really simple definition:
“Data lineage is defined as a data life cycle that includes the data's origins and where it moves over time. It describes what happens to data as it goes through diverse processes. It helps provide visibility into the analytics pipeline and simplifies tracing errors back to their sources.”
That’s easy enough. Fact is that it’s a really big problem for large organisations - specifically financial institutions as they have to comply with regulations like the Basel Committee on Banking Supervision's standard number 239 - which is all about assuring data governance and risk reporting accuracy.

Here’s a couple of really nice articles and videos that should really give you quite a bit of background.
