1. A computer-implemented method of generating data associated with a plurality of subject instances, the method comprising:

loading, by at least one processor, event stream data from a plurality of data sources, wherein the plurality of data sources are structured according to different schemas, wherein the event stream data includes a plurality of events associated with changes to one or more attributes associated with at least one of the plurality of subject instances, and wherein the event stream data corresponds to a first time period;

loading, by the at least one processor, correction data comprising a value of at least one attribute associated with the at least one subject instance of the plurality of subject instances;

generating, by the at least one processor based on the correction data, first modified event stream data corresponding to the first time period;

generating, by the at least one processor, a profile for a subject instance of the plurality of subject instances based on the first modified event stream data, wherein the profile comprises a chronology of changes in attributes associated with the subject instance, and wherein the correction data is distinct from the event stream data, the first modified event stream data, and the profile for the subject instance; and

using, by the at least one processor, at least a portion of the correction data to generate second modified event stream data, wherein the second modified event stream data corresponds to a second time period that differs from the first time period.
