Abstract: Embodiments of the present disclosure are directed to a system, methods, and computer-readable media for generating a hybrid data model. In embodiments, data feeds having different identities are used to generate profile fragments in one environment while relationships between the different identities are discerned in a separate environment. When a query is executed, an identity-based graph is generated to create a snapshot of the relationships determined at that time. Using the identity-based graph, those identities having a relationship to one another and to the query are determined. Profile fragments that correspond to the query-related identities are then aggregated together into a single hybrid data model.
