mvcc不是oracle提出的吧
http://en.wikipedia.org/wiki/Multiversion_concurrency_control#History 写道 Multiversion concurrency control is described in some detail in sections 4.3 and 5.5 of the 1981 paper "Concurrency Control in Distributed Database Systems"[1] by Philip Bernstein and Nathan Goodman—then employed by the Computer Corporation of America. Bernstein and Goodman's paper cites a 1978 dissertation[2] by David P. Reed which quite clearly describes MVCC and claims it as an original work.
