The development of educational software faces different problems. One of the major problems is how to find an appropriate way of visualization. The problem discussed in this paper is the visualization of a complex data structure for learners. For this problem, two requirements can be considered to be most important from a semantic point of view: a learner should be able to easily navigate the data structure of a learning software, and the visualization should improve the understanding of the underlying model.
A suitable technical solution has to provide the necessary flexibility. For applicability in different problem domains, the separate implementation of semantic and visualization aspects is required. In addition, a visualization technique should be able to support database interfaces, as databases are an efficient way to store complex data.
The solution presented in this paper is developed for a common technical environment. It is implemented by a framework of Java classes and tested in practice. The solution can be re-used for other problem domains. The first part of the paper deals with semantic modeling issues in cost accounting and presents some aspects of the underlying object model of the educational software Joker. The second section describes the software environment of the solution. The following two parts explain the concept and implementation.
