The security enhanced data platform is comprised of two primary subsystems and a host of supporting subsystems. The first primary subsystem is a document management system. A set of client side tools provides the user a way to specify classifications and compartments for selected areas of a document, and a way to save the document in the format required by the system in order to allow the system to enforce the rules and privileges dictated to the system. The second subsystem is a security enhanced database management system. In documents the system allows different user privilege requirements on the document as a whole as well as on pages, paragraphs, sentences, words, and/or letters of a word. A history of document changes is maintained to provide an audit trail after the fact of who did what changes, where those changes were made and when those changes were made.
