This presentation challenges the common understanding of conceptual, logical, and physical data models and offers some alternative ways to think about them. Rather than thinking of levels of data models, we should think in terms of stages of data models. Data modeling schemes differ in when particular constructs are introduced. For example, at what stage can we introduce foreign keys, identifiers, or first normal form? Do these belong in the initial stages of data models? I would argue not. The presentation wraps up with a chart showing the sequence in which various data modeling constructs are introduced.

Dr. Gordon C. Everest is Professor Emeritus of MIS and Data Management in the Carlson School of Management at the University of Minnesota (but continues to teach as an adjunct at Univ. of Minnesota). His Ph.D. dissertation from the University of Pennsylvania Wharton School entitled "Managing Corporate Data Resources" became the textbook entitled: "Database Management: Objectives, System Functions, and Administration" (McGraw-Hill, 1986, and remained in print until 2002!). He is also a contributing author of the CODASYL Systems Committee technical report entitled: "A Framework for Distributed Database Systems: Distribution Alternatives and Generic Architectures", and of the final technical report of the ANSI ASC X3 SPARC DBSSG Object-Oriented DBMS Task Group, released in 1991. He participated in the ANSI standards community to develop a Common Unified Data Modeling Scheme, investigate Object-Oriented Database Management Systems, and compile a glossary of terms relating to database management.
Dr. Everest is active in speaking to computer professional societies and consulting with large and small organizations in their use of computers, the development of information systems, and the organization and management of IS. His lecture presentations are well received and informative. He is an astute observer and interpreter of developments and trends in information technology and the computer industry.
His lecturing and research interests include logical database design methods and diagramming conventions, high-level data languages, selection and use of database management systems, object-oriented databases, data warehousing, CASE tools and the repository, data-centered systems development, organization and functions of database administration, data privacy and security, and the legal aspects of computing.
