,Performance Analysis — An Example,formance of the MT-index (see Section 4.4), the CH-index (see Section 4.3.1), and the H-tree (see Section 4.2.2) are compared. As usual there is no dominating approach for all hierarchy structures and query profiles, however, we are able to provide a few rules of thumb for index selection.

Type Hierarchy Indexing,type or, implicitly, to a subhierarchy and therefore to a set of types. In this chapter, the specific requirements, the technical issues, and some selected data structure solutions in the context of type hierarchy queries are discussed.

Aggregation Path Indexing,query involving more than one table usually contains explicit joins. For example let us assume a query involving Staff and Department, in particular, the retrieval of the names of staff persons working in the Process Automation department. Comparing the SQL-style query
