All data is contained in encapsulated objects managed by the operating system.
A trusted translator translates the MI code to a form that is executable on the hardware. In cases where objects are reused, the object manager either reuses them on a user basis, or clears all residual data. All users are registered via a user profile object created by a trusted administrator. Associated with each user profile is a one-way DES encrypted password. In addition, ease of postselection is provided via the SQL interface.
