VISIONARY: a Viewpoint-based Visual Language for Querying Relational Databases

  title={VISIONARY: a Viewpoint-based Visual Language for Querying Relational Databases},
  author={Francesca Benzi and Dario Maio and Stefano Rizzi},
  journal={J. Vis. Lang. Comput.},
The adoption of a visual interface can simplify the query formulation process in DBMSs by enabling naive users to interact with a friendly environment. In this work we propose a visual query language based on a diagrammatic paradigm, used for both data and query representation. The external data model is called vision and is made up of the visual primitives of concept and association. The external query model is based on the definition of a viewpoint, which is a perspective for accessing data… CONTINUE READING
