Abstract
The ability to gracefully accommodate dynamic evolution is considered essential in data-intensive office information systems. An important kind of conceptual database modification, there is an important subkind which involves changes to the fundamental semantics of objects, vis-a-vis their nature as symbolic, abstract, type (set), relationship (mapping), or behavioral (procedure). The authors examine object flavor evolution in the context of a simple, extensible object-oriented database model; this model is the kernel of prototype system termed PKM (personal knowledge manager) under development. The PKM object-oriented modeling constructs and operations are presented, along with a description and analysis of specific kinds of object flavor evolution.
