In Adobe Real-Time CDP, anIdentity Graphis a structural representation of the relationships between different identity namespaces that belong to an individual. It is the engine that enablesIdentity Stitching. When multiple datasets are ingested into the platform, they often contain different "fragments" of a customer’s identity—for instance, one dataset might identify a user by their Email, while another uses a loyalty_id. The Identity Graph manages these connections, ensuring that all data associated with these various IDs is aggregated into a single, unified profile.

Option B describes a transaction log, not an identity structure. Option C is incorrect because the graph linksidentities(people), not the datasets themselves. Option D describes a "Customer Journey," which is a visualization of interactions over time; while the Identity Graphenablesthe tracking of that journey by linking the sessions, the graph itself is strictly the map of identity overlaps. By maintaining this graph, Real-Time CDP can resolve identities in real-time, allowing for consistent messaging even as a customer moves between anonymous browsing and authenticated states across different devices and platforms.
