) Dmitri Boulanger Ulrich Geske GMD-FIRST, Rudower Chaussee 5, 12489 Berlin, Germany email: fdmitri,geskeg@first.gmd.de Abstract Using the logic programming system Minerva, Java and DMBS Oracle for development of a GIS-oriented constraint database systems is discussed. The central topic is a possibility to develop systems, which are approaching industrial standards. Namely, a technology for building applications, which need high quality graphical interfaces, which use data stored in commercial SQL databases and which enjoy advantages of of logic programming and constraint solving is the main goal. A number of important basic elements of the corresponding toolkit, which is currently under development, are introduced. Key Words: logic programming, Java, object-oriented programming, declarative semantics, constraint database systems, persistence, GIS applications 1 Introduction For a large class of important applications a declarative logic-based knowledge representation is a crucial ..
