Podcast With Dr. Peter Chen on the Entity Relationship Model and ADO.NET Entity Framework On Channel 9

If you are a SQL developer then you have probably heard of Dr. Peter Chen, he is the person who wrote the original paper on Entity-Relationship model (ER model).

From the site:
Dr. Peter Chen is a Fellow of ACM, IEEE, and AAAS and has received many prestigious awards including ACM/AAAI Allen Newell Award and IEEE Harry Goode Award. He has been listed in Who’s Who in America and Who’s Who in the World for more than 15 years.

Dr. Chen's original paper on the
Entity-Relationship model (ER model)
, published in 1976 is one of
the most cited papers in the computer software field. Based on one particular
citation database, Chen's paper is the
35th most cited
article in Computer Science.
It is the 4th most downloaded
paper from the ACM Digital Library in January 2005 (Communications of ACM, March
2005) even though the paper was published 30 years ago.

Dr. Chen’s work is a cornerstone of software engineering, in particular Computer-Aided Software Engineering (CASE). In the late 80’s and early 90’s, IBM’s Application Development Cycle (AD/Cycle) framework and DB2 repository (RM/MVS) were based on the ER model. Other vendors’ repository systems such as Digital’s CDD+ were also based on the ER model. Prof. Chen has made significant impact on the CASE industry by his research work and by his lecturing around the world on structured system development methodologies. Most of the major CASE tools including Computer Associates’ ERWIN, Oracle’s Designer/2000, and Sybase’s PowerDesigner (and even a general drawing tool like Microsoft’s VISIO) are influenced by the ER model.

In this podcast, Brian Beckman interviews Dr. Chen along with Jose Blakeley, Software Architect, SQL Server, and Britt Johnston, Director of Program Management, Data Programmability

The podcast is 51 minutes and 24 seconds
