Dr. Peter Chen: Entity Relationship Model - Past, Present and Future

Sign in to queue


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.

    Thanks for this video!

    I think in future - it will be use in robots brain.

    But tommorow - it be great tool for developer.

    Great idies - smart people.

    Good overview of design principle and practice.

    ER design tools come with enterprise price tags which often means that SQL Server designs are implemented without such tools in place.

    Its easy for Microsoft to push SQL Server as a product but you are remiss in not providing cheaper tools similar to ERWIN or ER/Studio to maintain schemas and serve third party maintenance.

    Thank you Dr. Chen and fellows. There is so much power in terms of what can be done with this concept and it's now up to those that contribute to it to understand it and build the appropriate engineering "intelligently" into it to harness this power. I could go on and on about this but to keep it short I would just like to say "Keep up the good work".

    Para nosotros los hispano-parlantes lo veremos subtitulado o traducido al lenguaje de Cervantes ?

    Very interesting, but how it is different from ANSI-SPARC approach?
