一本很基础的SQL讲解

<P>◆SQL Server 2005联机丛书提供了一些关于这个主题的有价值的信息，并且它可以作为使用SQL Server 2005实现数据分区的一个不错的起点。<BR>◆CLARiiON CX600 Web站点: <A href="http://www.emc.com/products/systems/clariion_cx246.jsp">http://www.emc.com/products/systems/clariion_cx246.jsp</A></P>
<P><STRONG>附录 A: 性能数值</STRONG></P>
<P>所有在这一部份展示的数值都是在我们使用SQL Server 2005的测试过程中得到的。该测试是在附录B，C以及D中记录的硬件平台上进行的。</P>
<P><STRONG>批量插入性能</STRONG></P>
<P>在我们的测试中，我们可以在SQL Server 2005中使用刚刚超过一个小时的时间导入25亿行。事实表的架构中包含了九个整型列，一个日期类型列，以及一个字符型列。</P>
<P>在这里展示的性能数值是在所有的线程以并行的方式执行并且分区架构基于策略I的环境下捕捉的。</P>
