比方说，如果在应用领域采用哈希表或者其他无序数据结构管理数据，可能会面临着将元素按照模式中的顺序设定重新装配的额外工作。
For example, if you manage data in hash tables or other unordered data structures in the application domain, you might face additional work re-assembling elements into the order set by a schema.
通常，一组有序数据的类别有自然的顺序，但尺度上相邻点之间的差距不必总是相同的。
Usually, categories for an ordinal set of data have a natural order, but the distinction between adjoining points on the scale is not necessarily always the same.
