Overview
Graph databases are emerging as a powerful fraud detection system, helping financial institutions identify and prevent fraudulent transactions before they occur. These databases are different to relational databases in many ways. Firstly, a graph data model focuses on relationships between data points. Secondly, it offers real-time querying for instant data analysis. Finally, graph databases are especially good at detecting patterns within complex datasets. When using a graph database, we start by ingesting customer, payment, and transaction data. Rule-based detection mechanisms can then be implemented to check for suspicious activities, and graph algorithms reveal any hidden patterns that point towards potential financial transaction card fraud.
