This Week in Neo4j – Graph Embeddings, Confluent with AuraDB, Intro Video, Liquibase, Data Stack Show


Hello, everyone!

Don’t miss our free hands-on training sessions (around two hours each day) from June 7 – 11. All folks who register for NODES can attend these sessions (scroll down for details).

In this week’s episode, we thank Alberto De Lazzari for his contributions to Neo4j. One of our Data Scientist colleagues, Clair Sullivan, posted an easy-to-follow tutorial about getting started with Graph Embeddings. Neo4j field engineer Alex Wolford posted an article about using Confluent with Neo4j AuraDB. We discovered a website, Code. Simply. Calmly. Clearly. that features video courses, one of which introduces you to Neo4j, Cypher, and importing data.

The folks at Liquibase just enhanced their products to work with Neo4j to help you manage a Neo4j database from development to production. Our Cloud Architect, David Allen, was interviewed by the folks at the Data Stack Show, where he describes everything you need to know to make the decision to use Neo4j for your application.

And finally, we pulled from our library of NODES 2020 videos a presentation about modeling processes in the automotive industry.

Cheers, Elaine and the Developer Relations team

Tutorial: Getting Started with Graph Embeddings in Neo4j


Clair Sullivan just published a tutorial to get you started with graph embeddings using the Neo4j Graph Data Science Library. The starting point for all machine learning is to turn your data into vectors/embeddings. Clair shows you how to use graph embeddings to turn your graph data into vectors that can be tuned for your machine learning process. You can do all of this with a Neo4j Sandbox so you don’t need to install anything on your system. In the tutorial, she goes into the algorithms used for the different types of embeddings you can create.

Confluent Cloud, Meet Neo4j AuraDB


Our colleague, Alex Woolford, published an article that explains how data that passes through Confluent Cloud can also be passed into a Neo4j Cloud instance, AuraDB. More and more enterprises are choosing to use managed services, such as Confluent Cloud and Neo4j AuraDB, which unburden them from needing to manage and maintain the hosting services. He shows a simple example of how to stream Confluent events into Neo4j, where he uses a set of technologies which include Kafka, Python, Docker, REST API, and, of course, Cypher.

Code. Simply. Calmly. Clearly.


Vincent D. Warmerdam has an impressive website for learning called Code. Simply. Calmly. Clearly. This site is a collection of 74 video courses on a variety of technical topics. One of the courses teaches you how to get started with Neo4j Desktop and import CSV data into Neo4j. It’s a great course to go through if you want a simple introduction to Cypher.

Liquibase Now Supports Neo4j for Database DevOps


Liquibase has expanded support for DevOps to include integration with Neo4j databases. Their product enables engineers to accelerate their development workflow and streamline deployment of database applications. Liquibase is used to implement test automation for a variety of application databases.

The Data Stack Show Podcast: Graph Databases & Data Governance


David Allen – along with Kostas Pardalis and Eric Dodds, hosts of the Data Stack Show – had an hour-long discussion about Neo4j. In this podcast, David educated us on what Neo4j is, why a graph database is important, some tidbits about how Neo4j works under the covers, how Neo4j can scale, and how Neo4j can be used to work with event streams.

NODES 2020 Video of the Week: Scalable, Reactive Product Development Framework for the Automotive Industry


Last year at NODES, Elena Kohlwey and Uwe Kloss, from RLE International Group, presented an overview of how they analyzed the needs of the automotive industry. They describe how they used a combination of process graphs and knowledge graphs to develop the data model for the application.

Final Reminder: Pre-NODES 2021 Hands-on Training Sessions


We hope that you will or have already registered for NODES 2021. The week before our online conference, we will host two-hour, hands-on training sessions led by our Developer Relations team members.
