A processor generates a relationship tree model, wherein the set of data fields each correspond to a node in the relationship tree model. A processor prunes the relationship tree model. Responsive to an update to a data field of the set of data fields, a processor promulgates the update using the relationship tree model to generate an updated set of insight data. A processor outputs the updated set of insight data. ## Claims ### Claim 1 A computer-implemented method for maintaining data synchronization, the computer-implemented method comprising: scanning, by one or more processors, a set of data fields at each stage of a data analysis process;
