Dr. Peter 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.
Profesor 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 addition to Dr. Chen, I'm joined by Architect Jose Blakeley who works on the ADO.NET Entity Framework, which is of course based on the core principals of Dr. Chen's Entity Relationship Model. This is a very interesting conversation with an industry pioneer that
covers the history of the Entity model, clearly defines what an Entity is, and delves into the future of Entities in this data driven world of ours. Enjoy.See Dr. Chen's original Entity Relationship Model paper.
