For the full paper, please download it from the ACM Digital Library by searching “Peter Pin-Shan Chen” or “Peter Chen”. ) (This paper is one of the most cited papers in the computer field.  It was selected as one of the most influential papers in computer science in a survey of over 1,000 computer science professors.)
	*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.)

	*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.
