Detecting Complex Fraud Patterns with ArangoDB
Feed: Blog – ArangoDB. Author: Vaidas Gasiunas. 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 ... Read More

Introducing Developer Deployments on ArangoDB Oasis
Feed: Blog – ArangoDB. Author: Ewout Prangsma. Today we’re announcing the introduction of Developer deployments as a beta feature on the Oasis platform. In this blog post, we’ll tell you what Developer deployments are, what you can do with them, what you should not do with them, and how to get started. What are Developer deployments? Since we launched Oasis, a deployment on Oasis has always been a highly available ArangoDB cluster. That is great for high availability, and it allows you to scale your deployment to incredibly large sets of data. Many customers have told us that they would ... Read More
ArangoBnB: Data Preparation Case Study
Feed: Blog – ArangoDB. Author: Christopher Woodward. This case study covers a data exploration and analysis scenario about modeling data when migrating to ArangoDB. The topics covered in this case study include: Importing data into ArangoDBDeveloping Application Requirements before modelingData Analysis and Exploration with AQL This case study can hopefully be used as a guide as it shows step-by-step instructions and discusses the motivations in exploring and transforming data in preparation for a real-world application.The information contained in this case study is derived from the development of the ArangoBnB project; a community project developed in JavaScript that is always open ...

C++ Memory Model: Migrating from X86 to ARM

Feed: Blog – ArangoDB. Author: Manuel Pöter. Over the past years, we have seen a shift in processors from the previously dominant x86 architecture to the more energy-efficient (and often cheaper) ARM architecture. This trend is true for both consumer hardware, e.g., Apple’s M1 SoC and also server hardware, e.g. AWS’s Gravitron processor. Given that the ARM architecture has a more relaxed memory model, this might have some subtle impact on C++ programs… With the introduction of multi-threaded execution in C++11, the standard also introduced a memory model. For many developers, this memory model is one of the least well-understood ... Read More
