An insert-friendly Numbering Scheme for XML Path expression indexing
Abstract:
Nowadays, large XML documents are very common. To retrieve desired parts from large documents efficiently, some fonn of indices is required. Many numbering and labeling schemes have been proposed as a representation of indexed nodes. However, many of these schemes suffer from insertion operation because renumbering is required after nodes are being inserted into the XML tree. Other schemes might support insertion without renumbering but have other limitations such as large space requirement and the position into which nodes can be inserted. In this project, we
propose a numbering scheme which fixes all of these problems. Moreover, our numbering scheme is 256-based (l byte) which provides a more compact representation of indexed nodes. We implement our numbering scheme and evaluate its perfonnance on query time and space requirement. The results show that our scheme's perfonnance is better than the existing methods.
