*The Entity-Relationship Model-- A basis for the Enterprise View of Data
Proc. of National Computer Conference, 1977, AFIPS Press, Pages 77-84  (file size: 1.05 Meg bytes) .   (This paper is one of the first papers arguing the importance of the "enterprise view" or "conceptual view" of data. It describes a set of operations for modifying ER diagrams.)

*A Preliminary Framework for Entity-Relationship Models
in: Entity-Relationship Approach to Information Modeling and Analysis, (edited by P. Chen), North-Holland (Elsevier), 1983, Pages 19 - 28   (file size: 1.14 Meg bytes) .   (This paper describes how different data models such as the hierarchical model.and the network model can be viewed as a member of the ER model family.  It also provides a basis for studying translation and equivalence of data models.)

Category 4:  Papers or Talks on the Accomplishments of Some of the Great Scientists

*From Goto-less to Structured Programming: the Legacy of Edsger W. Dijkstra, in: IEEE Software, Sept/October 2002, page 21.  This is a short article in memorial of Dr. Dijkstra’s contributions and influence to the field of programming and software development.  He died on August 6, 2002.   He was one of the 16 “software pioneers” given special recognition in the “Software Pioneers” conference in Bonn, Germany in 2001.   Dr. Peter Chen was also one of the 16 “software pioneers.” Unfortunately, three software pioneers passed away one year after the conference (In addition, to Edsger Dijkstra, Ole-Johan Dahl and Kristen Nygaard passed away in 2002; all three were Turing Award winners).

*Assessing the Impact of Jeff D. Ullman, A set of slides of a speech given at the symposium on December 6, 2002 at Stanford University in honor of Dr. Jeff D. Ullman’s retirement.
