Abstract:

La projection est une des techniques utilisées pour permettre de réduire les besoins en terme de taille mémoire nécessaire aux moteurs de requêtes XML (in-memory). L'idée sous-jacente à cette technique est simple : étant donnée une requête Q à évaluer sur un document XML D, au lieu de procéder sur D, la requête est évaluée sur un document D', plus petit que D, construit lors du chargement de ce dernier en mémoire, par élagage des parties de D inutiles pour Q. Le document D', est une projection du document initial D. Il est souvent de taille drastiquement inférieure à celle de D.Alors que cette

Abstract:

Pendant la dernière décennie, le format de données XML est devenu l'un des principaux moyens de représentation et d'échange de données sur le Web. La détection de l'indépendance entre une requête et une mise à jour, qui a lieu en absence d'impact d'une mise à jour sur une requête, est un problème crucial pour la gestion efficace de tâches comme la maintenance des vues, le contrôle de concurrence et de sécurité. Cette thèse présente une nouvelle technique d'analyse statique pour détecter l'indépendance entre requête et mise à jour XML, dans le cas où les données sont typées par un schéma. La co

Abstract:

XML, the eXtended Markup Language, is well believed to be the most common tool of the future for all data manipulation and data transmission. As a result, a lot of research and work have been done on XML. However, the current efforts on XML only focus on data queries. So far, there does not exist an XML data manipulation language that has reached its maturity to be accepted widely. Most of the existing XML databases only implement some kind of XML data query language and do not support data update operations. This thesis tries to make up the absence of XML data updates, and it begins wi

Abstract:

In the last decade XML became one of the main standards for data storage and exchange on the Web. Detecting XML query-update independence is crucial to efficiently perform data management tasks, like those concerning view-maintenance, concurrency control, and security. This thesis presents a novel static analysis technique to detect XML query-update independence, in the presence of a schema. Rather than types, the presented system infers chains of types. Each chain represents a path that can be traversed on a valid document during query/update evaluation. The resulting independence analysis is

Abstract:

We study the problem of updating XML views defined over XML documents. A view update is performed by finding the base updates over the underlying data sources that achieve the desired view update. If such base updates do not exist, the view update is said to be untranslatable and rejected. In SQL, determining whether a view update is translatable is performed using schema level analysis, where the view definition and the base schema are used. XML schemas are more complex than SQL schemas, and can specify recursive types and cardinality constraints. There are two kinds of view updates: single v

L'objectif des travaux de recherche présentés dans cette thèse est d'étudier des problèmes de sécurité et confidentialité qui se posent dans la gestion de données semi structurées distribuées. Si les techniques claniques de signature excluent toute modification des données signées, une approche plus souple est souvent nécessaire, dans laquelle des modifications (d'un type prédéfini) des données protégées par des signatures peuvent se produire. Dans ce but, nous avons proposé deux modèles. (XML Update Constraints et +/- Annotated Trees) pour spécifier des restrictions de mise à jour pour donnée

Les évolutions technologiques ont consacré l'émergence des services web et du stockage des données en ligne, en complément des bases de données traditionnelles. Ces évolutions facilitent l'accès aux données, mais en contrepartie soulèvent de nouvelles problématiques de sécurité. La mise en œuvre de politiques de contrôle d'accès appropriées est une des approches permettant de réduire ces risques. Nous étudions ici les politiques de contrôle d'accès au niveau d'un document XML, politiques que nous modélisons par des vues de sécurité XML (non matérialisées) à l'instar de Fan et al.

A software product line is a set of software-intensive systems that share a common, managed set of features satisfying the specific needs of a particular market segment or demand. Software product lines capitalize commonality and manage variation to reduce the time, effort, cost and complexity when creating and maintaining products in a product line. Therefore reusing core assets, software product line can address problems such as cost, time-to-market, quality, complexity of developing and maintaining variants, and need to quickly respond to market’s demands.

Abstract:

Within XML data management the performance of queries has been improved by using materialised views. However, modifications to XML documents must be reflected to these views. This is known as the view maintenance problem. Conversely updates to the view must be reflected on the XML source documents. This is the view update problem. Fully recalculating these views or documents to reflect these changes is inefficient. To address this, a number of distinct methods are reported in the literature that address either incremental view maintenance or update. This thesis develops a consistent incrementa

Abstract:

In this thesis, we make two major contributions that help the tasks of querying, updating, and managing XML data become quick and safe. First, we propose a new labelling scheme for dynamic XML data that supports the representation of the ancestor – descendant relationship and sibling relationship between nodes. Our unique way of labelling codes can also help users easily determine the depth (level) of the XML tree. Moreover, it also supports the process of updating XML data without the need of re-labelling existing labels, hence facilitating fast update. Some experimental works have been con
