Converting relational database schemas to XML schemas is important as applications originally written to manipulate relational data are converted to XML-enabled applications. Most research has focused on the challenging problem of efficiently extracting relational data through XML views. However, another important challenge is determining good XML schemas from existing relational schemas, so th...

The complexity of databases is increasing continually. The work of several designers become necessary. Therefore it is interesting to improve the design process with a new phase devoted to information integration , in order to take into account the designers'viewpoints. In this paper, we present an integration process which allows similarities to be discovered between the schemas under study. I...

Intercultural communication is concerned with communication across cultures. Since cultures as well as languages differ from one another in significant ways, speakers conceptualize the world around them in different ways. These cultural conceptualizations form part of the collective cognition of a speech community or cultural group. This paper is an attempt to delineate some cultural schemas in...

The capabilities of XSLT processing are widely used to transform XML documents into target XML documents. These target XML documents conform to output schemas of the used XSLT stylesheet. Output schemas of XSLT stylesheets can be used for a static analysis of the used XSLT stylesheet, to automatically detect the XSLT stylesheet of target XML documents or to reason on the output schema without a...

The use of schemas is a classical way of synthesizing, transforming and analyzing logic programs. Operations on schemas are needed, in particular, the semi-uniication of schemas with programs. Since the schemas used in the paper are second-order objects, the related semi-uniication is the second-order semi-uniication, which is decidable but NP-complete. The non-determinism implied by the NP-com...

Surprisingly enough, there has been few investigations for typing references of semistructured data and XML documents. This paper build on a previous proposal [7] introducing simple schemas with well-typed references and showing that such schemas, called normalized ref-schemas, are expressible as formulas of Hybrid Modal Logic. The aim of the present paper is to extend normalized ref-schemas in...

The most common implementation platform for multidimensional data warehouses is RDBMSs storing data in relational star and snowflake schemas. DW schemas evolve over time, which may invalidate existing analysis queries used for reporting purposes. However, the evolution properties of star and snowflake schemas have not previously been investigated systematically. This paper systematically invest...

Objectives: Early maladaptive schemas are valid representations of unpleasant childhood experiences that shape a person’s viewpoints of the world, and lead to clinical symptoms such as depression, personality disorders, and substance abuse. Given the importance of this matter, we conducted a research on early maladaptive schemas in substance-abusers, to allow more appropriate preventive m...
