		<description><![CDATA[<p>联机分析处理 (OLAP) 的概念最早是由关系数据库之父E.F.Codd于1993年提出的，他同时提出了关于OLAP的12条准则。OLAP的提出引起了很大的反响，OLAP作为一类产品同联机事务处理 (OLTP) 明显区分开来。</p>

		<description><![CDATA[<p>首先要感谢平平同学提供新的空间，新空间已经可以支持php5.0了，博客因此也顺利升级至最新版本。升级中遇到的主要问题是备份数据库时数据表编码乱码问题，本博的表使用了两种编码,gb2312与utf8，解决要点为连接数据库的客户端编码要与要备份的表编码一致，这样在备份的时候就不会有乱码问题了。</p>]]></description>

<p>解决方法，很无奈，将“6,666”中的&#8221;,&#8221;去掉，再进行转换。</p>]]></description>
