This paper deals with today’s state of the art in spatial database modelling. In particular, it discusses visual languages and related research. Major trends are described and an innovative language, termed sec- ond generation, based on a new concept called Spatial PVL is presented. This Plug-in for Visual Languages is used to extend the object-oriented standard language UML, and is implemented in a new freeware CASE tool called Perceptory.
