A Filter Flow Visual Querying Language and Interface for Spatial Databases
In this paper a visual approach to querying in spatial databases is presented. A filter flow methodology is used to consistently express different types of queries in these systems. Filters are used to represent operations on the database and pictorial icons are used throughout the language in filters, operators and spatial relations. Different granularities of the relations are presented in hi...
متن کاملVISIONARY: a Viewpoint-based Visual Language for Querying Relational Databases
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 exter...
متن کاملVisual Strategies for Querying Databases
A number of interfaces, based on different techniques which better exploit the human senses, have been recently suggested and implemented so enlarging the bandwith of the man-machine communication channel. The availability of graphical devices at low cost has given rise to a large diffusion of visual interfaces. The database field is particularly suited for such interfaces mainly because the da...
متن کاملA Data-Flow Approach to Visual Querying in Large Spatial Databases
In this paper a visual approach to querying in large spatial databases is presented. A diagrammatic technique utilising a data flow metaphor is used to express different kinds of spatial and non-spatial constraints. Basic filters are designed to represent the various types of queries in such systems. Icons of different types of spatial relations are used to denote the filters. Different granula...
متن کاملA Visual Language for Web Querying and
As XML is increasingly being used to represent information on the Web, query and reasoning languages for such data are needed. This article argues that in contrast to the navigational approach taken in particular by XPath and XQuery, a positional approach as used in the language Xcerpt is better suited for a straightforward visual representation. The constructs of the patternand rule-based quer...
