VisualMOQL: A Visual Query Language for Image Databases
Vincent Oria, Bing Xu, M. TAMER ÖZSU · 1998
Since most multimedia database systems are built on top of object or object-relational database systems, they inherit the underlying query facilities. The approach we present in this paper is in two steps. The first step is to design a multimedia query language that will be used as an internal language. The second step is to define an equivalent visual query language and a translator to translate a visual query into a query in the internal query language.
