Reformulation of XML Queries and Constraints

The authors state and solve the query reformulation problem for XML publishing in a general setting that allows mixed XML and relational storage for the proprietary data and exploits redundancies (materialized views, indexes and caches) to enhance performance. The correspondence between published and proprietary schemas is specified by views in...

XML Query Optimization in the Presence of Side Effects

The emergence of database languages with side effects, notably for XML, raises significant challenges for database compilers and optimizers. This paper extends an algebra for the W3C XML query language with operations that allows data to be immediately updated. They study the impact of that extension on logical optimization, join...

Adaptive Processing of Top-k Queries in XML

The ability to compute top-k matches to XML queries is gaining importance due to the increasing number of large XML repositories. The efficiency of top-k query evaluation relies on using scores to prune irrelevant answers as early as possible in the evaluation process. In this context, evaluating the same query...

Recursive XML Schemas, Recursive XML Queries, and Relational Storage: XML-to-SQL Query Translation

This paper considers the problem of translating XML queries into SQL when XML documents have been stored in an RDBMS using a schema-based relational decomposition. Surprisingly, there is no published XML-to-SQL query translation algorithm for this scenario that handles recursive XML schemas. This paper presents a generic algorithm to translate...

The Michigan Benchmark: Towards XML Query Performance Diagnostics

This paper proposes a micro-benchmark for XML data management to aid engineers in designing improved XML processing engines. This benchmark is inherently different from application-level benchmarks, which are designed to help users choose between alternative products. The authors primarily attempt to capture the rich variety of data structures and distributions...

Estimating Answer Sizes for XML Queries

Estimating the sizes of query results, and intermediate results, is crucial to many aspects of query processing. In particular, it is necessary for effective query optimization. Even at the user level, predictions of the total result size can be valuable in "Next-step" decisions, such as query refinement. This paper proposes...

Structured Materialized Views for XML Queries

The performance of XML database queries can be greatly enhanced by rewriting them using materialized views. This paper studies the problem of rewriting a query using materialized views, where both the query and the views are described by a tree pattern language, appropriately extended to capture a large XQuery subset....

Applying GRIPP to XML Documents Containing XInclude and XLink Elements

XML documents have an inherent tree structure well suited for reflecting hierarchical relationships in data. However, data often also contain relationships, which are not hierarchical but, for instance, cyclic or many to many relationships. These relationships may be modeled by embedding XInclude or XLink elements into an XML document. Unfortunately,...

Preserving XML Queries During Schema Evolution: A Guide to Writing Queries That Behave Well Across XML Schema Changes

As XML gains widespread use as an information exchange standard, the ability to persist, validate, and query XML documents becomes increasingly important. Moreover, with the proliferation of Web services and mash-ups, Web application developers increasingly need to query and transform XML messages, where such messages come directly from a Web...

SIGOPT: Using Schema to Optimize XML Query Processing

There has been a great deal of work in past years on processing and optimizing queries against XML data. Typically in these previous works, schema information is not considered, so that evaluation techniques can continue to be used even in the absence of one. However, schema information is often available...

CoXML: A Cooperative XML Query Answering System

The heterogeneity nature of XML data creates the need for approximate query answering. This paper presents an XML system that cooperates with users to provide user-specific approximate query answering. The key features of the system include, a query language that allows users to specify approximate conditions and relaxation controls; a...

Efficient XML Query Processing in RDBMS Using GUI-Driven Prefetching in a Single-User Environment

This paper addresses the problem of efficient processing of XQueries in single-user relational environment where the queries are formulated using a user-friendly GUI. The paper takes a novel and non-traditional approach to improving query performance by prefetching data during the formulation of a query. The latency offered by GUI-based query...

Exploit XML Indexes for XML Query Performance in DB2 9

DB2 9 provides pureXML storage and offers XQuery and SQL/XML as query languages. XML indexes are essential for high query performance, but their usage for query evaluation depends on how query predicates are formulated. This paper presents a set of guidelines for writing XML queries and creating XML indexes in...

The Importance of Algebra for XML Query Processing

Relational algebra has been a crucial foundation for relational database systems, and has played a large role in enabling their success. A corresponding XML algebra for XML query processing has been more elusive, due to the comparative complexity of XML, and its history. It is argued that having a sound...
