All data is contained in encapsulated objects managed by the operating system.
A user may obtain authority from any one of up to 16 groups. When 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. In addition, ease of postselection is provided via the SQL interface. In addition, the concepts of user state and system state are implemented in hardware, with full software support.
