Mediator systems aim to provide an unified global data schema over distributed heterogeneous structured and semi-structured data sources. These systems must deal with limitations on the query capabilities of the sources. This paper introduces a new framework for representing source query capability along with the algorithms needed to compute the query capabilities of the global schema from sour...

BACKGROUND The unfulfilled desire of millions of infertile couples worldwide to have their own biological children results in emotional distress. This study evaluated the emotional reactions of couples attending a combined infertility clinic in Kuwait and successful clients' perception of nurses. METHODS Quantitative and qualitative methods were used. The first phase was by structured intervi...

Methods: It is a qualitative research based on the Theory of Social Representations carried out with 80 academics of the Dentistry course. The data were collected through a semi-structured interview script, processed in the IRaMuTeQ and analyzed by the Descending Hierarchical Classification. The study followed the ethical standards recommended by Resolution n. 466/2012, obtaining approval from ...

Ever-growing data volumes demand for storage systems beyond current file systems abilities, particularly, a powerful querying capability. With the rise of XML, the database community has been challenged by semi-structured data processing, enhancing their field of activity. Since file systems are structured hierarchically they can be mapped to XML and as such stored in and queried by an XML-awar...

The help seeking and social integration needs of learners in a semistructured learning environment require specific support. The design and use of educational technology has the potential to meet these needs. One difficulty in the development of such support systems is in their validation because of the length of time required for adequate testing. This paper explores the use of a simulated lea...

This paper describes a method for creating structure from heterogeneous sources, as part of a concept base, or other information database. ‘Concept trees’ can grow from the heterogeneous sources when correct and consistent sequences of concepts are presented. The method maintains the key requirement of generality, allowing it to be used as part of a generic framework. The nature of the method a...

During past years we have developed the MOMIS (Mediator envirOnment for Multiple Information Sources) system for the integration of data from structured and semi-structured data sources. In this paper we propose a new system, MIKS (Mediator agent for Integration of Knowledge Sources), which enriches the MOMIS architecture exploiting the intelligent and mobile agent features.

Permutation based XML-conscious compressors permute the input document to improve the compression ratio and support efficiency of operations, such as queries or updates. One such compressor, XSAQCT, uses the properties of the permuted document, called an annotated tree, to these operations. This paper provides the formal background for the definition of an of D. It also provides an algorithm fo...

A line of research is presented aimed at specifying both logical and navigational aspects of semi-structured data sources such as Web sites through the unifying notion of schema. Gracefully supporting schemata that are huge or subject to change, the WG-Log language allows for a uniform representation of queries and views, the latter expressing customized access structures to site information. A...
