Talk:Edgar F. Codd

message: IBM did NOT ignore Codd's work until the "successes" of Larry Ellison. IBM was deeply involved in relational database research and the development of SQL in the early 1970s, before Ellison even got started. Even the unskeptical do not contend that Oracle delivered commercial product prior to late 1979, and other commercial relational products were well on the way in that time frame. Oracle's early product saw little success until the mid 1980s with products like Ingres having the early lion's share of the market. If anything, it was Ellison who ignored Codd's work -- the early Oracle product was far from meeting the principles of the relational model. Oracle did not achieve market dominance until much later and by that time IBM had established two relational products SQL/DS and DB2 in the market.

replies: text: ill be brief. Ibm was very much committed to todds work with many product groups involved. They wanted to release a product that was both robust, and could fit into a much larger context than oracles niche product. Oracle just released first, and has been extremely agressive in marketing pricing and aquisitions. For more than a few years, oracle was thought to be  in serious trouble, against both INGRESS and IBMs SQL aind DB2. Consider  that despite oracles dominance DB2 is still widely used. --22:47, 26 August 2011 (UTC)

message: Did Dr. Codd get his PhD in Computer Science as it says here in this article? I thought it was in Communication Sciences? See Edgar F. Codd: A Tribute and Personal Memoir from ACM SIGMOD. 69.224.58.213 (talk) 08:48, 27 June 2009 (UTC)
replies: text: says: "From 1961 to 1965 Codd was on leave from IBM while he undertook Ph.D. studies at the University of Michigan. Codd's Ph.D. was in communication sciences and his thesis was on self-reproducing computers consisting of a large number of simple identical cells, each of which could interact in a uniform manner with its four immediate neighbors. Academic Press eventually published this work in 1968 as Cellular Automata."  Ferkel (talk) 23:09, 18 April 2011 (UTC)

message: The statement "Then IBM included in its Future System project a System R subproject" is not correct or at least misleading". System R was a Research project and preceded Future System. Future System was a later Development project. I know. I was part of System R. See "A History and Evaluation of System R" at www.cs.berkeley.edu/~brewer/cs262/SystemR.pdf or the System R website at www.mcjones.org/System_R .

Also misleading: "but put in charge of it developers who were not thoroughly familiar with Codd's ideas, and isolated the team from Codd". The System R project was in San Jose, where Ted was, and researchers were relocated from IBM Yorktown to IBM San Jose to be on the project. In particular, Don Chamberlin and Ray Boyce, who invented SEQUEL/SQL, were quite aware of Ted's work. Read this oral history of Don for his interactions with Ted: http://archive.computerhistory.org/resources/access/text/Oral_History/102702111.05.01.acc.pdf .

But all things considered, an unsigned comment on the talk page wouldn't count as source either. 91.66.90.117 (talk) 22:38, 14 January 2017 (UTC)

message: Codd was British and he was a computer scientist, but can he really be described as a "British Computer Scientist" when all his professional career as a computer scientist was spent in the United States?

message: Can someone shed some light on why Codd wasn't an ACM fellow a dozen years after he got his Turing Award. Both recognition are from the same organization, and the former is supposed to be many times more selective than the latter, no?

message: Codd was an IBM Fellow according to this: http://www.research.ibm.com/resources/news/20030423_edgarpassaway.shtml  However, he is listed in the Wikipedia "IBM employee" category. Contrast with Benoit Mandelbrot, who is not listed in the employee category, but rather the fellow category.  I assume this is an oversight, but perhaps there is some rationale?

message: The un-cited anecdote about "a little know fact as to how Codd came up with the term 'normalization' " is highly dubious. "Normalization" is a common, ordinary mathematical term for this type of operation, one that would have been quite familiar to him. The entire paragraph smells prankish. ~ Ningauble (talk) 13:41, 17 September 2009 (UTC)

message: Codd continued to develop and extend his relational model, sometimes in collaboration with Christopher J. Date. One of the normalised forms, the Boyce–Codd normal form, is named after him.   — Preceding unsigned comment added by 209.90.32.9 (talk) 17:54, 11 March 2019 (UTC)
