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 DE...
