Hi. I'm having trouble locating articles or books or any other source that gives information about the Bachman method of data modelling (also know as information modeling, entity relationship modelling/diagramming, ER'ing, IM'ing, data analysis, etc.). I would appreciate it if you could mail/post any references you have. Thanks. Bill Biesty

The company was started many years ago by Charles Bach- man who is known for his work before that in data models and database research. Bachman has a style of Entity-Relationship modeling which differs from the original Chen proposals. THis has been incorporated into the various Bachman products. So there is a "Bachman method of data modelling." My only source of informa- tion on the Bachman model has been from vugraphs at presentations made by he and representatives of his company at a couple conferences. (Nothing publish- ed that I have knowledge of -- though there may be somewhere.) On the other hand, John Zachman (of IBM's LA Scientific Center) has been a proponent of a style of information systems analysis/modeling for many years. It has nothing specifically to do with styles of diagrams, etc. but is more related to the architectural aspects of information systems design. John's approach is to relate architectural approaches from other engineering domains to software. He's a very entertaining speaker who makes his points quite clearly, i.e., it is easy to know what he is claiming about his position. I do not know that anything other than the article mentioned above has been published. I have seen John several times at conferences. I also know he has begun the seminar/workshop route as I have seen his name in conjunction with a couple over the past year. Speaking only for myself, of course, I am... Scott P.

You can find extensive bibliographies for data modelling, plus E-R and Bachman diagrams (along with a basic introduction to data modelling) in any good database text. I would recommend either McFadden & Hoffer _Database Management_, 3e, Benjamin Cummings, 1991, ISBN 0-8053-6040-9 or Date _An Introduction to Database Systems_, Volume 1, 5e, Addison Wesley, 1990, ISBN 0-201-51381-1. -- -------------------------------------------------------------------------- Roy Schmidt | #include <disclaimer.h> Indiana University | /* They are _my_ thoughts, and you can't Graduate School of Business | have them, so there! */
