I asked ChatGPT 4 the "first book" question and got a better response. I then asked it, "when was "A Guide to the IBM Relational Database Interface" written?"
It informed me, ""A Guide to the SQL/DS Relational Database Interface," written by James Martin and Adrian R.D. Norman, was published in 1987. " Plus a lot more.
Of course, no such book was ever written or published. When corrected, "Wasn't that in fact a research paper?"
ChatGPT said: "You are correct. Upon closer examination, it appears that the reference I provided earlier is not for a book, but rather for a research paper or article related to SQL/DS, published in 1988."
You know the rest. No such paper.
