We address the problem of minimal-change integrity maintenance in the context of integrity
constraints in relational databases. We assume that integrity-restoration actions are limited …

As Web applications manipulate an increasing amount of XML, there is a growing interest in
storing XML data in relational databases. Due to the mismatch between the complexity of …

The eXtensible Markup Language (XML) is widely used to transmit data across the Internet.
XML schemas are used to defile the syntax of XML messages. XML-based applications can …

The ambient logic is a modal logic that was proposed for the description of the structural and
computational properties of distributed and mobile computation. The structural part of the …

Recent applications are seeing an increasing need that publishing XML documents should
meet precise security requirements. In this paper, we consider data-publishing applications …

We address the problem of minimal-change integrity maintenance in the context of integrity
constraints in relational databases. Using the framework proposed by Arenas, Bertossi, and …

In this paper we propose a mediator architecture for the querying and integration of Web-
accessible XML data sources. Our contributions are (i) the definition of a simple but …

Having a database design that avoids redundant information and update anomalies is the
main goal of normalization techniques. Ideally, data as well as constraints should be …

Constraints are important, not only for maintaining data integrity, but also because they
capture natural probabilistic dependencies among data items. A probabilistic XML database …

In the last few years, XML has been widely used as a logical data model, and several
database applications are modeled in XML. To model a database application in XML, we …
