并且可以使用方括号操作符以相同的方式访问所有数据项，它支持将不同类型的有序数据项分段。
And you access all the items in the same way using the square bracket operator, which supports slicing different types of sequential items.
如Wilson所示，（各种类型和近似的）最佳适合方案在实际负载下相对于其他一般方法（像是最先适合）趋向于产生最少的分段。
As shown by Wilson et al, best-fit schemes (of various kinds and approximations) tend to produce the least fragmentation on real loads compared to other general approaches such as first-fit.
同样，这两种类型的索引都可以指定一个FILLFACTOR，并可以指定存储选项来控制创建索引的位置以及是否对索引进行分段。
Similarly, both types of indexes can specify a FILLFACTOR and both can specify storage options that control where the index is created and whether or not it is fragmented.
