问题描述
我已经看到有关数据库市场份额的数据显示IBM略微领先于甲骨文的b $ b。然而，以更精细的粒度查看数据显示，IBM在大型机数据库市场中占据了巨大的市场份额，在Unix中排在第二位的是
市场，以及在Windows市场上排在甲骨文和微软之后的第三位。在Unix市场中，IBM市场份额是DB2 UDB，Informix，
我的问题是，如果有人知道，那么DB2 UDB的市场份额是什么，如果有的话，还可以用于
Unix（以及Windows，如果可用的话）？
谢谢，
Joseph
I''ve seen data about database market share that shows IBM slightly ahead
of Oracle. However, looking at the data with a finer granularity shows
IBM with a huge lead in market share in the mainframe database market,
running in second place behind Oracle in the Unix market, and a distant
third place behind Oracle and Microsoft in the Windows market. In the
Unix market, the IBM market share is an aggregation of DB2 UDB, Informix,
and Sequent Numa-Q based systems.
My question is specifically what is the market share for DB2 UDB for
Unix (and also for Windows if available) if anyone knows?
Thanks,
Joseph

基数将滞后并更有利于Oracle。
为什么这很重要？

See http://www.gartner.com/reprints/microsoft/106576.html
Note that DB2 has almost certainly narrowed the gap further since
2001. But also that the figures are for new licence revenue - existing
base figures will lag and favour Oracle more.
Why does this matter?

对于一些较小的数据库可能很重要，但Oracle，SQL Server和
DB2将会存在很多年。我不会指望其他任何人在中期或长期处于其他地方。
It might matter for some of the lesser databases, but Oracle, SQL Server and
DB2 will all be around for many years. I would not count on any of the
others being around in the intermediate or long term.
