Abstract
In this paper, we present an object-oriented spatial database system called KROSS. It makes the most of the object-oriented concepts of the ObjectStore DBMS such as the inheritance mechanism, object identity, and complex objects. We propose a spatial signature (SAS) data model in order to support spatial object types and their polymorphic operations, and design a spatial object-oriented query language (SOQL) for handling spatial objects. SOQL provides an integrated mechanism for the graphical display of spatial objects and the retrieval of objects. To support an efficient hybrid query evaluation, we use an object-driven method for processing hybrid queries.
