From the Blog: Detecting Complex Fraud Patterns

Check out our latest blog post that presents a case study of how to use AQL queries to detect complex money laundering and financial crime patterns. It covers:

  • Complex graph traversal and visualization
  • Advanced AQL filtering and aggregation
  • Query Parallelism
  • The WINDOW function introduced in ArangoDB 3.8

Webinar: Exploring Abstract Syntax Trees with ArangoDB

Sarah from Slack 29.09.2021 Webinar

It’s not too late to sign up for our next webinar with Sarah Henkens, Software Engineer at Slack.

Sarah will share how Slack performs code analysis by modeling abstract syntax trees as a graph model in ArangoDB. We hope you can join us to learn how to design effective graph data models and utilize AQL to traverse an AST.

Community Spotlight: ArangoDB Community GitHub and Interactive Tutorials 

Do you have a project or tool that the ArangoDB community might be interested in?

If so, we would love to add it to our growing list of repositories in the ArangoDB Community GitHub organization. This GitHub organization serves as a place for more people to find out about your project and, if necessary, even help you develop it!

ArangoX & ArangoX Ecto Adapter 

This week we highlight not one but TWO repositories, both in the Elixir ecosystem!

First up is ArangoX, an implementation of DBConnection for ArangoDB. This project supports VelocyStream, active failover, transactions, and streamed cursors. ArangoX is developed and maintained by GitHub community members suazithustra and otaq.

ArangoX Ecto Adapter

The ArangoX Ecto project leverages the ArangoX project to bring seamless Ecto support for the Elixir ecosystem. This project is developed and maintained by Tom Grozev and Kian Meng Ang.

Thanks again to the community members that bring these projects to life. If you have a project you would like to see highlighted here please let us know!

Apple AirPods Giveaway!

Our Interactive Tutorials repository has a library of Python notebooks available covering the full spectrum of ArangoDB features. Although we cover a lot of topics, something is missing … YOUR notebook! 

Starting today and running until the end of September, the first 25 people who have a notebook merged into the main branch will receive a swag box (one per person). EVERYONE who has an accepted PR will be entered to win a set of custom Apple AirPods! Each notebook (subject to approval) gets you an extra entry.

To get started, visit the repository and follow the contribution instructions. Notebooks should cover topics related to ArangoDB, such as:

  • A unique approach to getting started with AQL
  • An exciting tutorial covering another ArangoDB concept
  • A novel approach you took to solve a machine learning problem using ArangoDB
  • A notebook showcasing how you use ArangoDB in your application
  • Any other notebooks that get people excited about using ArangoDB

We are pretty lenient when it comes to approving community notebooks, but some content may require revision before being accepted or may not be accepted. 

See the Community Notebook Challenge page for up-to-date information.

Disclaimer: We will make our best effort to ship to most countries, within reason. If for any reason, we aren’t able to due to laws or shipping restrictions of the country, or some other unforeseen reason, we may need to select another winner at our discretion and/or not send out the swag box.
