		<description>哈哈~博主你看看这片帖子：
主题：请做架构的朋友一起讨论下SNS中好友动态功能建模的设计

		<description>说的很好。 我正在做一个这样的动态系统。 思路和你的好擦不多，当然没你想的这么深入。不过我想应该还有很多地方可以做优化。</description>

		<description>我表的设计(部分) 
TrendType(反射到相应的类)
objectId(主体，可以是用户，可以是其他任何)
EventId 事件（某个object &#039;s Title）
EventBody( what...)
....    当然这个数据不管怎么样都会很大（前提这是个好网站，呵呵）首先一定要做表分区，之后做数据模版缓存，最后在呈现动态的时候保存当前动态（时间范围）（前提是有用户服务器，若干）</description>
