Systems and methods are disclosed for implementing a data stream correlation user interface. The data stream correlation user interface provides workflows for selecting individual data sources from a matrix of data sources, identifying individual data fields of the data sources, establishing criteria for determining correlations between them, and reviewing and enabling user verification of correlated data sources. Correlations may be established based on the values of data fields in individual records of the data sources, and may be determined based on correspondences or associations between the values, lookup tables, formulas, user-specified criteria, or other relationships.
