Within predifined packages the user can create classes with their attributes and polyhierarchical relations to other classes without changing the database or application. A lot of surfing tools, adaptable import and export interfaces and a sophisticated selection tool help to easily access data. Thus MORIS is a system suitable for many areas of environmental research and control.Text/Conference Paper
