A database management (DM) computing device for reducing an amount of data stored within an enhanced database while ensuring that data remaining within the enhanced database is able to satisfy a plurality of user queries is described. The DM computing device is in communication with the enhanced database and a secondary storage database. The DM computing device is configured to receive a log data file identifying a number of times each data field in the enhanced database has been queried, rank the data fields based on the number of times each data field has been queried, and identify least-queried data fields from the ranked data fields, wherein the least-queried data fields are defined by rules in a memory. The DM computing device is also configured to store in the secondary storage database the least-queried data fields from the enhanced database, and remove from the enhanced database the least-queried data fields.
