Entity Resolution vs Identity Graph: What’s the Difference and Why It Matters

Entity resolution and identity graphs are critical components in managing data across systems, with each serving distinct yet interconnected roles. Entity resolution identifies and consolidates records referring to the same real-world entity into a single authoritative record, employing deterministic and probabilistic matching to address variations and inconsistencies. In contrast, an identity graph is a connected data structure that maintains a live, queryable profile of an entity by linking all associated identifiers, enabling real-time analysis and updates. Graph databases, like TigerGraph, excel in handling both processes at scale by matching entities through relationship patterns and maintaining a continuously updated identity network without the delays of ETL pipelines. This integration is crucial for applications such as fraud detection, Customer 360 initiatives, and compliance, where real-time data and accurate identity mapping can prevent operational issues like stale data leading to missed fraud or fragmented customer profiles. TigerGraph's unified platform facilitates the seamless operation of both entity resolution and identity graph maintenance, ensuring that organizations can act on the most current view of their data for improved decision-making and efficiency.
