Castelli D. Three levels of reuse for supporting the evolution of database schemas. In: Conceptual Modeling - ER'99. 18th International Conference on Conceptual Modeling. Proceedings (Paris (France), November 15-18 1999). Proceedings, pp. 1 - 15. E. Metais (Ed.) (ed.). (Lecture Notes in Computer Science). Springer, 1999.
This paper presents a reuse technique which permits to simplify redesign that may occur when the conceptual schema is changed. This technique is based on the reuse of the refinement steps, the verifications and the schemas of the original design.F or each kind of reuse, the technique specifies the conditions under it can be applied and how the reused components should evolve.
