The KStore is a datastore made up of a forest of interconnected, highly unconventional trees of one or more levels. One KStore can be added to an existing KStore to create an updated KStore by traversing the trees of the KStores and incrementing the count fields to reflect the added counts of analogous nodes. New KStore structure is added as needed. A KStore can be subtracted from an existing KStore to create an updated KStore by traversing trees KStores and decrementing the count fields in the updated KStore to reflect the subtracted counts of analogous nodes. KStore structure is removed as needed. Portions of a KStore can be added or subtracted from another KStore by isolating the paths to be used for updating. Instead of incrementing or decrementing counts, a dataset of individual records can be recreated from the KStore.
