Path-expression Queries over Multiversion XML Documents
2003
International Workshop on the Web and Databases
Preserved Fulltext
In this paper we address the problem of evaluating path expression queries on multiversion XML documents. ...
Such queries are typically implemented on static (i.e., non-versioned) documents as path joins, using numbering schemes that maintain the structural relationships among the document elements. ...
Given the tree structure of XML documents, path expression queries represent the core of XML query processing. ...

In this paper, we examine the problem of supporting efficiently complex queries on multiversioned XML documents. ...
Also, there has been much recent interest in supporting complex queries on XML data (e.g., regular path expressions, structural projections, DIFF queries). ...
Path-expression queries need to maintain the logical document order and UBCC does not.
Path-Expression Queries A path-expression query is described by a regular expression on the document tree. ...

We believe that the key contribution of this system is an improved schema-based clustering storage strategy efficient for both XML querying and updating, and powered by a novel memory management technique ...
We present a native XML database management system, Sedna, which is implemented from scratch as a full-featured database management system for storing large amounts of XML data. ...
As XQuery queries and XML update statements [14] access nodes in an XML document with XPath expressions, the descriptive schema plays a role of a naturally built index for evaluating XPath expressions ...

This paper describes our research activities in developing efficient systems for the management of multiversion XML documents in an e-Government scenario. ...
Recently, the multi-version management system has migrated to a different architecture ("native" approach) based on a multi-version XML query processor developed on purpose. ...
The statement following the standard XQuery FLWR syntax allows users to express selection constraints on the variable $a iterating over the nodes returned by the path expression path. ...

With the advent of native and XML enabled database systems, techniques for efficiently storing, indexing and querying large collections of XML documents have become an important research topic. ...
Based on this scheme, we extend the application of path join algorithms to implement most parts of the XPath query language specification and add support for keyword search on element and attribute contents ...
Background XML query languages like XPath [2, 6] or XQuery [4] use path expressions to navigate through the logical, hierarchical structure of an XML document, which is modelled as an ordered tree. ...
