Abstract
A method for constructing a change database reduces the footprint of a standard longitudinal data database and increases the manageability of the data for many applications. The change database concatenates representations of a time period for the change, the direction of the change, and the value of the change into a single string. The change database is constructed by creating foundation files from formatted historical data, constructing change files from these foundation files, and iteratively creating master files that encapsulate the change data.
