Abstract
Structured hierarchical documents containing data, such as XML documents, are input and stored in a structured database such as an XML database. The hierarchical structure of the document is represented as a collection of subtrees in which a subtree can be updated without affecting other subtrees. The relationship between neighboring subtrees is maintained by providing a link node in each subtree that stores a reference to the neighboring subtree. Subtrees can be organized into larger structures to support efficient searching of the structured database.
