Integrity constraints for XML
2003
Journal of computer and system sciences (Print)
Preserved Fulltext
In this paper, we extend XML DTDs with several classes of integrity constraints and investigate the complexity of reasoning about these constraints. ...
Integrity constraints have proved fundamentally important in database management. The ID/IDREF mechanism provided by XML DTDs relies on a simple form of constraints to describe references. ...
Acknowledgments We thank Peter Buneman, Richard Hull, Leonid Libkin and Frank Neven for helpful discussions. We would also like to thank the referees for valuable comments. ...

The main contribution of this paper is a generic grammarware for validating XML integrity constraints. Indeed, we use an attribute grammar to describe XML documents and constraints. ...
We thus explain the main parts of this novel algorithm and we report on experiments showing that our method allows for an effective and efficient validation of XML functional dependencies (XFD). ...
Introduction This paper deals with integrity constraint validation on XML documents. ...

This becomes particularly important when integrating data from multiple data sources with overlapping data and when such constraints can express data merging rules at the target. ...
The schemas can be any combination of relational or XML schemas, and can be independently designed. ...
On the other hand, our techniques operate directly at the XML level and form the basis for an integrated solution for XML query rewriting in the presence of both lossy mappings and target constraints. ...

Integrity constraints for XML documents are mainly defined through XML schemas: DTD and XML Schema. ...
However, XML schemas do not have support for all existing kinds of domain integrity constraints in SQL databases. ...
Other relevant future work comprises the control of other kinds of integrity constraints, like the ones pointed out before, and the development of a tool for creating and validating XDC documents. ...

This paper extends our previous work by showing our grammarware as a generic way for validating XML integrity constraints, both from scratch and incrementally during document updates. ...
Indeed, our generic attribute grammar can stand for any XML constraint validator, provided that the constraint is defined with paths. ...

Some novel conceptual models are proposed to capture the hierarchical structure of XML. A set of requirements for a good conceptual models for XML are concluded. ...
However, there is no standard methodology for designing XML data at conceptual level. In this paper, we give a survey to conceptual modeling for XML in terms of the basic models they employ. ...
One important kind of data semantics is the integrity constraints. We emphasize that to integrate the integrity constraints into conceptual model is important for the applications. ...

The provided system is all XML-based which poses query in XML form, transforms, and integrates local results in an XML document. ...
Constraints in global schema and mappings are used for source selection, query optimization,and querying partitioned and replicated data sources. ...
This layer integrates local generated results into a single XML document format. For this purpose it first converts all the results into XML format and then integrates them in a single XML document. ...

Third, a practical project is to use integrity constraints to distinguish good XML design (speci cation) from bad design, along the lines of normal forms for relational schemas. x( (r; x) ! ...
