Object-Oriented Geo-Information Processing in Modulex

This paper presents some of the basic features of MODULEX, an object-oriented database programming environment, and shows how they apply to the requirements of modelling and manipulating object in a typical geo-scientific engineering application. Our approach and first experiences with object-oriented database technology in an application environment that involves objects in geodetic networks and the associated complex engineering actions on those objects are also reported. The chosen geo-scientific application environment is characterized by objects with complex structure represented as large, persistent sets, and actions whose complexity is determined not only with the complexity of objects, but also with the complexity of underlying mathematical algorithms. The importance of extensibility, inheritance and a specific form of polymorphism is also demonstrated for the chosen application environment.
