Development of today's advanced applications is increasingly being accomplished using multi-faceted modeling. For example, the areas of simulation and workflow modeling generally need data modeling as a foundational capability. In addition, simulation modeling and workflow modeling can be used together, synergistically. Based on the experience of the LSDIS group in developing systems and models, we have found that establishing rich linkages between disparate models works better than having one comprehensive unified model. In addition, we agree with the consensus that two dimensional models are generally considered to be easier to create and understand than one dimensional models. Furthermore, just as richly linked text is referred to as hyper-text, richly linked diagrams may be referred to as hyper-diagrams. Two modeling toolkits, METEOR Designer and the JSIM Modeling Toolkit, illustrate the advantages of using such approaches.
