Abstract :
The paper presents an approach viewed from an application perspective to cope with changes in an evolutionary information system. It presents a visual specification design, change, and redesign. The VSM includes change management to make resolvable schema changes transparent for existing programs so the redesign or modification of the system can be avoided. It also provides change history to assist a designer in redesigning the specification when the change is unresolvable
