Rajasekar Krishnamurthy, Raghav Kaushik, Jeffrey F. Naughton
2003 Lecture Notes in Computer Science  
In particular, for the XML publishing of relational data and for "schema-based" shredding of XML documents into relations, there is no published algorithm for translating even simple path expression queries  ...  Recently, the database research literature has seen an explosion of publications with the goal of using an RDBMS to store and/or query XML data.  ...  XML Publishing (XP): here, the goal is to treat existing relational data sets as if they were XML.  ...

Querying XML Views of Relational Data

Jayavel Shanmugasundaram, Jerry Kiernan, Eugene J. Shekita, Catalina Fan, John E. Funderburk
2001 Very Large Data Bases Conference  
A general way to publish relational data as XML is to provide XML views over relational data, and allow business partners to query these views using an XML query language.  ...  XML has emerged as the standard data exchange format for Internet-based business applications. This has created the need to publish existing business data, stored in relational databases, as XML.  ...  We would also like to acknowledge the contributions of past members of the XPERANTO project, including Rimon Barr, Mike Carey, Dana Florescu, Zack Ives, Ying Lu, and Subbu Subramanian.  ...

A general technique for querying XML documents using a relational database system

Jayavel Shanmugasundaram, Eugene Shekita, Jerry Kiernan, Rajasekar Krishnamurthy, Efstratios Viglas, Jeffrey Naughton, Igor Tatarinov
2001 SIGMOD record  
In addition, our proposed technique enables users to query seamlessly across relational data and XML documents.  ...  Since relational schema generation is a physical database design issue -dependent on factors such as the nature of the data, the query workload and availability of schemas -there have been many techniques  ...  As a starting point, XPERANTO automatically creates a d e f a u l t X M L view, which is a low-level XML view of the underlying relational database.  ...

An XML-Based Approach to Publishing and Querying the History of Databases

Fusheng Wang, Carlo Zaniolo
2005 World wide web (Bussum)  
There is much current interest in publishing and viewing databases as XML documents.  ...  Indeed, using XML, the histories of database relations can be naturally represented by temporally grouped data models.  ...  Publishing each table as an XML document with columns as elements A natural way of publishing relational data is to publish each table as an XML document by converting relational columns into XML elements  ...

Improving Query Performance Using Materialized XML Views: A Learning-Based Approach [chapter]

Ashish Shah, Rada Chirkova
2003 Lecture Notes in Computer Science  
The main contribution of this paper is to show that selective materialization of data as XML views reduces query-execution costs in relatively static databases.  ...  Our learning-based approach precomputes and stores (materializes) parts of the answers to the workload queries as clustered XML views.  ...  Conclusions and Future Work We have described a view-and learning-based solution to the problem of reducing total query-execution times in relational data sources with XML interfaces.  ...

XBiT: An XML-Based Bitemporal Data Model [chapter]

Fusheng Wang, Carlo Zaniolo
2004 Lecture Notes in Computer Science  
The increasing popularity of XML and XQuery offers a unique opportunity to change this situation, inasmuch as these support temporal information much better than relational tables and SQL.  ...  This is the important conclusion claimed in this paper where we show that valid-time, transaction-time, and bitemporal databases can be naturally viewed in XML using temporally-grouped data models; then  ...  Publishing Relational Databases in XML. There is much current interest in publishing relational databases in XML. One approach is to publish relational data at the application level.  ...

Automatic Generation of SQLX View Definitions from ORA-SS Views [chapter]

Ya Bing Chen, Tok Wang Ling, Mong Li Lee
2004 Lecture Notes in Computer Science  
Although XML is the dominant standard for publishing and exchanging data for Internet-based business applications, data is typically stored in relational or object-relational databases.  ...  The generated view definitions are SQL queries with XML extension (SQLX) that can be directly evaluated on object-relational databases to materialize the views.  ...  Introduction In this work, we consider XML views in a particular case where the XML data are stored in an object-relational database.  ...

DTD-Directed Publishing with Attribute Translation Grammars [chapter]

Michael Benedikt, Chee Yong Chan, Wenfei Fan, Rajeev Rastogi, Shihui Zheng, Aoying Zhou
2002 VLDB '02: Proceedings of the 28th International Conference on Very Large Databases  
We present a framework for publishing relational data in XML with respect to a fixed DTD.  ...  In data exchange on the Web, XML views of relational data are typically required to conform to a predefined DTD.  ...  To exchange data currently residing in relational databases, one needs to publish it in XML, i.e. to transform the data into an XML format.  ...

Fusheng Wang, Carlo Zaniolo
2003 Lecture Notes in Computer Science  
There is much current interest in publishing and viewing database-resident data as XML documents.  ...  We investigate various approaches used for publishing relational data, and identify and select those which are best for representing and querying database histories.  ...  Multiple Tables as a Single XML Document: Flat Structure Another way to publish relational data is to publish multiple relational tables into a single XML document (Figure 3 ), but still with the flat  ...
