人们在Windows上使用db2吗？ [英] Are people using db2 on Windows?
问题描述
我想知道有多少人在Windows上使用db2？
我知道db2原生于AS400，安装量大约为800,000。
谢谢！
这是道琼斯新闻社2003年5月21日所说的话：
微软 SQL Server在Windows机器上占据了45％的市场份额，扩展了其作为最广泛使用的
数据库的领先优势，高于上一年度的39％b / b
。 Oracle拥有27％的市场份额，而IBM拥有22％的市场份额。
IBM的份额主要是DB2，因为Informix几乎没有分享
IBM购买之前的Windows。

我不确定你的意思是说DB2是AS400的原生代码。
IBM的关系数据库是在大型机VSE操作系统上启动的
20世纪80年代早期的SQL / DS产品。不久之后，DB2 on MVS
（现在称为DB2 for OS / 390或z / OS）。
当前称为DB2 for Linux的产品，Unix和Windows在1989年左右开始作为
OS / 2数据库管理器？它后来成为DB2 / 2（OS / 2）和/ b
DB2 / 6000（对于AIX）。在1990年代中期增加了对Windows的支持。支持
Linux是在1990年代后期添加的？在最新版本的
中已经删除了对OS / 2的支持。
DB2 / 400产品总是与其他产品分开，但我相信它<
首次出现在1990年代早期（我在1993年简要使用过它）。它原生于
AS400 OS，而不是单独的产品，因为它最初是在现有AS400文件系统之上的附加
层。也就是说，可以通过本机AS400文件系统或通过SQL访问相同的数据。 DB2 / 400（或DB2 for i
系列）与DB2的根或在大型机或Linux / Unix / Windows平台上运行的当前产品
几乎没有关系。
我们一直在高效地使用它 - 用于数据仓库，并且成功实现了很好的成功 - 用于4年的纯Windows生产。在此之前，它是关于MVS的DB2
。

I wonder how many people are using db2 on Windows?
I know db2 is native to AS400 which has about 800,000 installations.
Thanks!
Here''s what the Dow Jones news service said on May 21, 2003:
"Microsoft''s SQL Server expanded its lead as the most widely used
database on Windows machines with 45% of the market, up from 39% last
year. Oracle had 27% of this market, while IBM had 22%."
The IBM share would be mainly DB2, as Informix had little share on
Windows before IBM bought them.

I am not sure what you meant by saying that DB2 is native to AS400.
IBM''s relational database started on mainframe VSE operating system as the
SQL/DS product in the early 1980''s. It was shortly followed by DB2 on MVS
(now called DB2 for OS/390 or z/OS).
The product currently known as DB2 for Linux, Unix, and Windows started as
OS/2 Database Manager about 1989?. It later became DB2/2 (for OS/2) and
DB2/6000 (for AIX). Support for Windows was added in mid 1990''s. Support for
Linux was added late 1990''s?. Support for OS/2 has been dropped in the
latest release.
The DB2/400 product was always separate from the others, but I believe it
first appeared in early 1990''s (I used it briefly in 1993). It is native to
AS400 OS and not a separate product because it was originally was an add-on
layer on top of existing AS400 files systems. That is, the same data could
be accessed via native AS400 files systems or via SQL. DB2/400 (or DB2 for i
series) has little to do with the roots of DB2 or the current product
running on mainframe or Linux/Unix/Windows platforms.
We''ve been using it productively - for data warehousing, with great
success - for 4 years of pure Windows production. Prior to that it was DB2
on MVS.
