Abstract

This paper describes the historical developments of the Entity-Relationship (ER) model from the 1970s to recent years. It starts with a discussion of the motivations and environmental factors in the early days. Then, the paper points out the role of the ER model in the Computer-Aided Software Engineering (CASE) movement in the late 1980s and early 1990s. It also describes the possible role of the author's Chinese cultural heritage in the development of the ER model. In that context, the relationships between natural languages (including Ancient Egyptian hieroglyphics) and ER concepts are explored. Finally, the lessons learned and future directions are presented.
