"The Influence Index doesn't merely measure who's talking on Twitter, but it also measures how much someone is affecting the conversation," wrote Leonhardt.
“影响指数不只考虑在Twitter上发布信息的人,它更用于衡量人对于他人对话的影响。”莱恩哈特写道。
Your influence index can be counted in the same way, although not for free.
你的影响力指数也可以通过同样的方法计算,虽然不是免费的。
You can define guidelines that influence only a few attributes of an execution plan, such as index specification for a certain table in the query or join order for a pair of tables.
可以定义那些只影响执行计划的某些属性的准则,比如查询中的某个表的索引说明,或者一对表的连接顺序。
