今年6月Gartner公司发布了2007年主流数据库市场分析报告,根据该报告(见下图),我们可以看到 oracle 继续以48.6%的份额遥遥领先。
Note: Others include InterSystems (0.82%), Hitachi (0.81%), Fujitsu (0.68%), MySQL (0.33%), Ingres (0.23%), Pervasive Software (0.15%) and EnterpriseDB (0.05%).
我们看看2007年它们各自的增长率:
从上图我们可以看到,从增长率来看,Microsoft第一, oracle 紧追其后,而IBM只有10%,这也说明随着SQL Server 2005的推出,Microsoft加快了追赶 oracle 的脚步。
下图是Top 3跟其他数据库的对比:
下图是各数据库软件在各种OS上的收入和增长情况:

Note: Windows Desktop RDBMS software revenue stood at $4 million in 2006 and $6.5 million in 2007.
下图是各数据库所能支持的OS:
从中我们也可以看出,微软最大的弱点是无法跨平台,只能在Windows下使用,这样势必就影响其应用与推广。
