Abstract
A system (20) and method for managing change in software systems and applications manages change for both transient and persistent objects in a domain independent, non-intrusive, object-oriented fashion. The system (20) and method are designed and implemented as a combination of two abstract machines (22,24) consisting of a set of interface functions (25,26) visible to the application, and an internal or private state (27,28) which is hidden from such application. Applications use the interface functions (25,26) to obtain the services of this change management system (20) and method. Since the internal state of such system (20) and method is outside the application, change management is provided as a service without the need for altering or adding onto application data structures and interfaces.
