Abstract
A method is disclosed that can be used to reduce the size of the indexesof structured-documents. The method uses the schemaof structured documents, in particular XML documents, to determine the existence of certain deterministic relationshipsamong the indexing components. Using such knowledge when indexing the data and formulating query execution plans can greatly reduce the size of the indicesand allow querying of such documents more efficiently.
