In this paper we introduce and formally define
Query by Browsing (QBB), a scalable, relationally complete
visual query language based on the desktop user interface
paradigm and tuple relational calculus that allows the formulation
of complex queries over relational, entity-relationship,
object-oriented and XML data sources on a variety of handheld
and desktop platforms. It is to our knowledge the first visual
query language to combine the important characteristics of
usability, scalability, expressive power and flexibility. We support
these claims by demonstrating the similarity of the QBB
paradigm to the popular desktop user interface paradigm, by
relating it to relational calculus and relational algebra and
by describing Chiromancer II, a web-based implementation
of the QBB paradigm for handheld devices. We also discuss
ways in which non-relational sources can be represented and
queried and compare QBB to related work in the area of visual
query languages for a variety of data models. We finally offer
conclusions and thoughts for future work.
