This module is useful if you manage data which has a lot of on/off attributes like active, inactive, deleted, important, etc. If you do not want to add an extra column for each of those attributes you can easily specify them in one integer column. A bit field is a way to store multiple bit values on one integer field. The main benefit from this module is that you can add additional attributes to your result class whithout the need to deploy or change the schema on the data base.
