Résumé
This paper presents a comprehensive approach to legacy data quality assessment and improvement. It is based on an initial database reverse engineering phase that allows to recover implicit constructs, that is, structures and constraints that have not been explicitly declared in the database schema, using program analysis techniques. These constructs then serve as a basis for detecting data inconsistencies, identifying unsafe program fragments, and proposing necessary improvements at both the database and program sides.
