  1. Dynamic Queries for VisualInfomation Seeking Ben Shneiderman Departement of Computer Science, Human-Computer Interaction Laboratory and Institute for Systems Research University of Maryland 1993

  2. Généralités (1/3) • But : interroger des Bases de données complexes • Les langages tels que SQL ne sont pas toujours bien adaptés. Dynamic queries

  3. Généralités (2/3) • Solution proposée : les requêtes dynamiques (dynamic queries) • Définition : les requêtes dynamiques décrivent l’utilisateur interactif qui contrôle les paramètres visuels des requêtes Dynamic queries

  4. Généralités (3/3) • Les requêtes obtenues directement pour la manipulation et la démonstration de résultats graphiques est très avantageuse dans beaucoup de situations • trafic aérien • location de maisons Dynamic queries

  5. Exemple : table des éléments chimiques Dynamic queries

  9. Evaluation • Evaluation des resultats obtenus Dynamic queries

  10. Avantages • Présentation visuelle de comportements des requêtes • Présentation visuelle des résultats • Rapide, incrémental et actions réversibles • Sélections par pointeurs • Immédiate et feedback continue Dynamic queries

  11. Inconvénients • Matériels et logiciels ne sont pas toujours bien adaptés. • Algorithmes pas toujours efficaces pour une performance rapide des reponses attendues. • Utilisation d’affichage graphique rapide qui n’est pas toujours disponible. • Requêtes élaborée (group by, string matching, etc.) ne sont pas complêtement traitées • Pour les handicaps visuels, besoin d’autres alternatives Dynamic queries

  12. Perspectives :Requêtes dynamiques aujourd’hui ? • Dang, G., North, C., and Shneiderman, B. (April 2001)Dynamic Queries and Brushing on Choropleth MapsProc. International Conference on Information Visualization 2001, 757-764. IEEE Press (July 2001). Dynamic queries
