CONTRIBUTION À L'ANALYSE DE L'IMPACT DE MISES À JOUR SUR DES VUES ET SUR DES CONTRAINTES D'INTÉGRITÉ XML.

Abstract : IN THIS THESIS, WE ARE POSITIONED IN A DYNAMIC CONTEXT, WHERE THE XML DATA EVOLVE OVER TIME AND ARE SUBJECT TO A SET OF UPDATES, AND WE FOCUS ON TWO MAJOR PROBLEMS, WIDELY STUDIED IN RELATIONAL DATABASES: -THE DETECTION OF THE IMPACT OF A SET OF UPDATES ON A VIEW, DEFINED BY A QUERY. -THE DETECTION OF THE IMPACT OF A SET OF UPDATES ON THE SATISFACTION OF A FUNCTIONAL DEPENDENCY. WE DIFFER FROM PREVIOUS WORK ON TWO MAIN POINTS: (1) WE ASSUME THAT DATA SOURCES ARE UNAVAILABLE A PRIORI AND WE STUDY BOTH PROBLEMS BY PERFORMING A STATIC ANALYSIS OF DEFINITIONS UPDATES, AND THE VIEW OR THE FUNCTIONAL DEPENDENCY . MOREOVER, IF AN XML SCHEMA CONSTRAINING THE STRUCTURE OF THE DATA IS AVAILABLE WE USE THIS ADDITIONAL INFORMATION IN OUR ANALYSIS TO DETECT MORE CASES OF INDEPENDENCE BETWEEN THE UPDATES AND THE VIEW OR THE FUNCTIONAL DEPENDENCY. (2) WE TAKE THE OPTION TO USE AS A MECHANISM FOR SELECTING NODES IN THE DEFINITION UPDATES, VIEWS AND FUNCTIONAL DEPENDENCIES, A FORMAL LANGUAGE BASED ON THE USE OF REGULAR TREE PATTERNS, TO DEFINE QUERIES CALLED 'REGULAR TREE QUERIES' (ABBREVIATED AS RARS).
