Design the flexibility, maintain the stability of conceptual schemas

摘要

A well-designed Conceptual Schema should be flexible enough to allow future change. But current methods for the design and maintenance of Conceptual Schemas are not based on insigth into the actual evolution of the Conceptual Schema over time. The relationships between the demand of flexibility, the quality aspect stability, and evolution of the Conceptual Schema are not well understood or investigated. Advance in current design practices and maintenance of information systems depends on the understanding of the relation between actual properties of a Conceptual Schema and its evolution.
