"Dawn M. Wolthuis" wrote in message
"Evolution of Data-Base Management Systems", (ACM Computing Survey, Vol 8,
number 1, March 1976) by Fry and Sibley, discusses GIRLS as the forerunner to
Informatics MARK IV (not GIM).
Under the section of references for 'DBMS prior to 1968", it includes
"Generalized information retrieval and listing system" Datamation (Dec. 1962) by
J.A. Postley and T.D. Buettell.
So Dwight Buettell worked on GIRLS before he went to the TRW department that
created GIM.
> There are detailed flow charts that Don Nelson prepared in the early 60's as
the spec for GIRLS. I thought he did that while at TRW, with Pick joining him
later.
Is Dwight Duettell still living?
