In other cases, the preferred drill path may lead from one dimension table to another. You ve already seen an example of this process. Figure 7-1 showed order dollars by category, and then built additional detail by adding month. In that case, the drill path followed was: Categories Months This path ignores the product attribute hierarchy, instead adding detail from a different dimension the day dimension. Some products reconcile this activity with the hierarchical notion of drilling by observing that there is a hierarchy in each dimension. In addition to the product hierarchy, for example, there is a hierarchy in the day dimension. The day hierarchy for five years of data might look like this: All Days (1) Years (5) Quarters (20) Months (60) Days (1826) The user s initial view of order_dollars in Figure 7-1, then, can be defined in terms of two hierarchies. The report shows orders at the category level in the hierarchy, and for all days in the day hierarchy. When date is added to this view, the user is drilling within the day hierarchy. Notice that moving from all days to month has skipped over two levels in the day hierarchy years and quarters.

It is possible to add dimensional detail without the aid of an attribute hierarchy at all. Two characteristics of information make this possible. First, the cardinality of an attribute, or the number of instance values it takes on, is not necessarily determined by where it lies in a hierarchy. Second, some instance values may be found under multiple parents. For example, the attribute product_color in Figure 7-2 is associated with the lowest level of detail in the product hierarchy. It is quite possible the products are only available in a dozen colors. When viewing order dollars by color, the data is highly summarized, even though product color is at the bottom of the attribute hierarchy. Adding brand_name to this view results in a large increase in detail, despite the fact that brand appears at a higher level of the product hierarchy. This phenomenon can be explained by expanding the simple attribute hierarchy of Figure 7-1 to represent the relative cardinality of all attributes within the product table, rather than grouping them into one set of levels. This perspective acknowledges the presence of a separate hierarchy that moves from color to product. Adding brand to a view of products by color, however, does not involve any of these hierarchies.

Attribute hierarchies describe relationships among dimension attributes. Products fall within brands; brands fall within categories. We can express these rules without referring to actual data. Another form of hierarchy may exist among instances of dimensions. For example,

employees report to other employees. This kind of hierarchy can only be expressed by referring to specific employees. The relationship is recursive; there may be any number of levels in the hierarchy. At each level of the hierarchy, the attributes of the employee are the same. Other examples of instance hierarchies include departments falling within departments, companies owning other companies, and parts being composed of other parts. Like an attribute hierarchy, an instance hierarchy may be useful in studying facts. Suppose, for example, that products are sold to corporate customers. Companies may own other companies, which in turn own other companies. It may be useful to roll up all transactions to top-level parent companies. We can then explore the data by drilling down through multiple levels of ownership. This process does not involve adding or removing attributes to our view of a fact; companies at each level share the same basic dimensional data: names, types, locations. Instead, drilling within an instance hierarchy requires tracing through the ownership relationships between companies. This kind of hierarchy can be accommodated in a dimensional model and is fully discussed in 10, Recursive Hierarchies and Bridges.
