Multiversion Concurrency Control Before InterBase?

From Craig Stuntz's Weblog:



Multiversion Concurrency Control In Computing Literature Before InterBase

Multiversion concurrency control is described in some detail 4.3 and 5.5 of this paper by Philip Bernstein and Nathan Goodman -- then employed by the Computer Corporation of America. [Note: An ACM Portal subscription is required to read the full text of the paper.] Bernstein and Goodman's paper cites a 1978 dissertation by D.P. Reed which quite clearly describes MVCC and claims it as an original work. Reed's paper is cited by 66 other authors, according to the Guide to Computing Literature, and Bernstein and Goodman's, 180 times.
