A system links data objects associated with a common event and includes at least one processor. The system compares data objects associated with an entity and corresponding to a plurality of events for the entity, wherein the data objects are stored within a plurality of different source systems. Candidate data objects associated with a common event for the entity are identified based on the comparing. The candidate data objects are linked to form a set of data objects representing the common event for the entity. Embodiments of the present invention further include a method and computer program product for linking data objects associated with a common entity.
