Peter Pin-Shan Chen (Chinese: 陳品山; born 3 January 1947) is a Taiwanese-American computer scientist and applied mathematician.
[2] During this period, he was a visiting professor once at Harvard in '89-'90 and three times at Massachusetts Institute of Technology (EECS Dept.
In 1984, under the sponsorship of the United Nations, he taught a one-month short course on databases at Huazhong University of Science and Technology in Wuhan, China, and was awarded as Honorary Professor there.
From 2008 to 2014, he was an Honorary Chair Professor at the Institute of Service Science at National Tsing Hua University, Taiwan.
In 2003, Chen received the IEEE Harry H. Goode Memorial Award at the IEEE-CS Board of Governors meeting in San Diego.
[8] He also founded the Data & Knowledge Engineering journal for publishing and disseminating scholarly research results.
Chen first published an abstract and presented his ER model in the First Very Large Database Conference in September 1975, the same year of a paper with similar concepts written by A. P. G.
The ER model was adopted as the meta-model ANSI Standard in Information Resource Directory System (IRDS), and the ER approach has been ranked at the top methodology for database design and one of the top methodologies in systems development by several surveys of Fortune 500 companies.
In the late 1980s and early 1990s, IBM's Application Development Cycle (AD/Cycle) framework and DB2 repository (RM/MVS) were based on the ER model.
Chen has had a significant impact on the CASE industry through his research and his lecturing around the world on structured system development methodologies.
Chen investigated this linkage as an invited expert of several XML working groups of the World Wide Web Consortium (W3C).
The ER model also serves as the foundation of some of the recent work on Object-oriented analysis and design methodologies and Semantic Web.
His innovative research results were adopted in commercial computer performance tuning and capacity His Ph.D. thesis at Harvard was one of the first studies of cost-performance optimization models of multi-level memory/storage hierarchies.
He was a co-author of the storage technology article in early versions of a computer encyclopedia book published by McGraw-Hill.
In recent years, he led a multidisciplinary research team in developing new efficient and effective techniques in identifying terrorists and malicious cyber transactions.
