Join Us at the Open EDSIG Board
Meeting at ISECON
The annual open EDSIG Board meeting is scheduled for October 17,
1998 from 5:30-7:00pm in San Antonio at this year's ISECON. This
year has been a very active one for the Board which has already met
twice. The establishing of a ListServe, compliments of Board member
Bill Tastle of Ithaca College, has proven to be a most effective tool for
maintaining full Board participation on EDSIG initiatives. The
Board is seeking active membership participation. Agenda items
for the business meeting will include:
- The President's Message to the membership.
- EDSIG Officer Reports.
- The current status of JISE.
- Discussion of a revised set of EDSIG By-Laws.
- Plans for ISECON'99.
- Nomination of candidates of Officers/Board members for 1999.
EDSIG Unveils First Web Page
EDSIG now has a Web site where EDSIG activities and issues as well
as links to resources for IS Educators can be found. Currently,
the Web page is hosted at Pace University in New York under the URL
csis.pace.edu/edsig, but
will eventually be moved to another location under the URL
"www.cise.org".
EDSIG wishes to thank Mr. Ted Dixon, an Information Systems graduate
student at Pace University, for his fine work in assisting in the
development of the Web page.

Historically Speaking
This year marks the thirtieth anniversary of E.F. Codd's initial
investigations of the management of large commercial databases.
One year later, he published the landmark article "Derivability,
Redundancy, and Consistency of Relations Stored in Large Data
Banks" in the IBM Research Report in which the idea of the
relational database model was introduced. Codd, an IBM researcher
working in San Jose, found his ideas enthusiastically embraced
by the academic and research communities. His worst detractor -
IBM Marketing!
It seems that IBM was promoting its strategic database product, IMS,
which was grounded in the hierarchical database model. Meanwhile,
Codd was trumpeting the superiority of the relational model, and
thus by implication was undermining the IMS marketing effort. In
fact, other vendors introduced commerical relational database
products before IBM - INGRES for one. Codd eventually left IBM.
IBM needn't have worried. IMS has had a long and highly successful
place in the industry until very recently, and remains a mainstay
of many key legency applications. As it turned out, the early
implementations of the relational model were notably poor performers.
One joke that floated around IBM in the 1980s went something like
this: What's the question that matches the answer "Lassie, Rin Tin
Tin, and DB2." The question: "Name two movie stars and a dog!"
With increased memories and improved query optimization techniques,
relational products, including DB2, overcame their early performance
problems and now dominates today's database world. Codd, however,
continues to maintain that no commercial product has ever fully
implemented all the features of the relational model.
