Index Structures for Path Expressions
1999In recent years there has been an increased interest in managing data that does not conform to traditional data models, like the relational or object oriented model. The reasons for this non-conformance are diverse. On the one hand, data may not conform to such models at the physical level: it may be stored in data exchange formats, fetched from the ...

Combining Tree Structure Indexes with Structural Indexes in Query Evaluation on XML Data
2005There are a variety of structural indexes which have been proposed to speed up path expression queries over XML data. They usually work by partitioning nodes in the data graph into equivalence classes and storing equivalence classes as index nodes. The size of a structural index is never larger than the size of the data graph.
