Ces besoins sont formalisés au sein dŠun schéma conceptuel du domaine dŠapplication, typiquement un diagramme Entité-Relation (ER). Le processus de validation de ces besoins demeure pourtant problématique car la représentation visuelle du modèle ER ne permet pas toujours une bonne compréhension par les utilisateurs finaux. En revanche, des prototypes dŠinterfaces utilisateurs peuvent être utilisés comme un moyen plus efficace pour exprimer, capturer et valider des besoins en termes de données. Considérant ces interfaces comme une vue physique de la base de données à concevoir, il est possible d'en dériver le schéma conceptuel sous-jacent en combinant des techniques de rétro-ingénierie, de transformation et d'intégration de schémas. Cet article présente les fondements d'une approche interactive et outillée mettant en oeuvre ces principes.

Several research projects are being led in this field, and more generally in the mobile guiding domain. PDAs do suffer limitations, especially when it comes to user interaction and display of information. That's why bringing sound enhancement can improve the usability and user-friendliness of PDA-based applications.

These requirements are formalised into a conceptual schema of the application domain, that has proved ...

In this process it is assumed that the end-user, with minimal training, is able to sketch a prototype interface of the future application, from which the conceptual model of the application domain can be derived semi-automatically. In particular, the information contents of the electronic forms can be extracted and conceptualised through reverse engineering and integration techniques to significantly contribute to the conceptual schema of the future database.
