Cost Effective Database Design: An Integrated Model.
Rob Gerritsen · Defense Technical Information Center (DTIC) · 1977
Relationships between conceptual schema design and internal schema design are considered. The author's earlier work on automatic derivation of conceptual schemata is reviewed, and a constrained optimization model for design of internal schemata is introduced. Trade-offs represented in the model are discussed, and a method for obtaining access frequency estimates is described. (Author)
