Sample text

There is no loss of generality in this assumption, since we can always create a new tree type with a new root record type which combines all the record types in the forest type into a single tree type. Moreover, without loss of generality, we assume that the database consists of a single tree record. A hierarchical path (or simply a path) is a sequence of records starting from a root record and following alternately from a parent record to a child record. For example, STUDENT, COURSE, TEACHER is a path.

The fundamental operation of hierarchical navigation is that of traversing tree records by specifying paths starting from a root record to the record we are trying to locate. As in the network model tree traversal is done one record at a time. At each stage when the user is navigating through the database a currency pointer is maintained by the DBMS, which is the record identity of the most recently accessed record. Traversal of a tree record is performed in a depth-first [Tarn, AHU83) manner as follows, starting by making the root record the current record: 1) visit the current record if it has not already been visited, else 2) visit the leftmost child record not previously visited, else 3) go back to the parent record.

V) Nothing is a regular expression unless it follows from (i) through (iv). The class of regular languages (or regular sets) over L is the minimal set of languages containing 0 as well as the singletons {a}, for all a E L, and closed under union, concatenation and Kleene star. It can be shown that a language is regular if and only if it can be described by a regular expression. In addition, a language is regular if and only if it is accepted by a DFA. This fundamental result was proved in a seminal paper by Kleene [Kle56].
