Embodiments provide a computer-implemented method for managing interval boundaries of electronic records. The method includes receiving electronic records, associating a first selection criterion and second selection criterion with the electronic records, and associating some of the electronic records with a group based at least in part on determining that the second selection criterion is within a predetermined range of a first threshold. The method further includes generating a group record that identifies the group, associating a third selection criterion with the group record, the third selection criterion being within the interval boundaries, and identifying an expiration of an interval boundary based at least in part on determining that the electronic data representing the third selection criterion is within a predetermined range of a second threshold.
