A detailed journey into deploying a DC2DC replicated environment

When we thought about all the things we wanted to share with our users there were obviously a lot of topics to choose from. Our Enterprise feature; ArangoSync was one of the topics that we have talked about frequently and we have also seen that our customers are keen to implement this in their environments. Mostly because of the secure requirements of having an ArangoDB cluster and all of its data located in multiple locations in case of a severe outage. 

This blog post will help you set up and run an ArangoDB DC2DC environment and will guide you through all the necessary steps. By following the steps described you’ll be sure to end up with a production grade deployment of two ArangoDB clusters communicating with each other with datacenter to datacenter replication.

Detecting Complex Fraud Patterns with ArangoDB

00General, Graphs, how to, Query LanguageTags: , ,

Introduction

This article presents a case study of using AQL queries for detecting complex money laundering and financial crime patterns. While there have been multiple publications about the advantages of graph databases for fraud detection use cases, few of them provide concrete examples of implementing detection of complex fraud patterns that would work in real-world scenarios. 

This case study is based on a third-party transaction data generator, which is designed to simulate realistic transaction graphs of any size. The generator disguises complex financial fraud patterns of two kinds: 

  • Circular money flows: a big amount of money is going through different nodes and comes back to the source node.
  • Indirect money transfers: a big amount of money is sent from source node to a target node over a multi-layered network of intermediate accounts.

Word Embeddings in ArangoDB

02General

This post will dive into the world of Natural Language Processing by using word embeddings to search movie descriptions in ArangoDB.

In this post we:

  • Discuss the background of word embeddings
  • Introduce the current state-of-the-art models for embedding text
  • Apply a model to produce embeddings of movie descriptions in an IMDb dataset
  • Perform similarity search in ArangoDB using these embeddings
  • Show you how to query the movie description embeddings in ArangoDB with custom search terms
