Between the key attribute and each non - key attribute bound to columns in the main dimension table 在鍵屬性與綁定到主維度表中各列的每個非鍵屬性之間定義。
Of a database dimension is the attribute to which all non - key attributes in the dimension are linked directly or indirectly 上圖所示的多維數(shù)據(jù)集有四個維度: route 、 service 、 time和measures 。
Between the attribute bound to foreign key in the secondary table and each non - key attribute bound to columns from the secondary table 在綁定到輔助表中外鍵的屬性與綁定到輔助表中各列的每個非鍵屬性之間定義。
For example , you might want to define a natural hierarchy , a custom sort order , or dimension granularity based on a non - key attribute 例如,您可能需要定義自然層次結(jié)構(gòu)、自定義排序順序或基于非鍵屬性的維度粒度。
If there are no defined relationships between attributes , analysis services will aggregate all non - key attributes from the key attribute 如果屬性之間沒有定義的關(guān)系,則analysis services將根據(jù)鍵屬性聚合所有非鍵屬性。
