Identity data collected from network flows is managed and graphed according to a hierarchical schema that reduces data storage requirements and enhance database querying efficiencies. Preferably, the schema comprises a set of objects, such as a 'source' object, a 'time' object, and an &#x201c;identity&#x201d; object. A source object represents a source of an identity, namely, where an identity comes from. A time object represents a time bucket along a particular time frame corresponding to when an identity appears on the network. An identity object represents the actual identity itself. As each distinctive identity data is detected, it is added to the graph, preferably just once, and relationships between particular pairs of identities are identified. The resulting graph has significantly-reduced storage requirements, and it facilitates the discovery of linked identities much more efficiently, even when the identities are not directly connected.
