In this paper we study the integration of Model Management and Hypertext systems to
produce a Hyper Model Management System (HMMS). Model Management Systems constitute
a class of software that is designed to support the construction, storage, retrieval, and
use of models in the context of decision support systems (DSS). Hypertext systems allow
users to split information into data fragments which the user can browse to find information
by taking non-linear paths in computer based texts. It has been suggested that DSSs
should be conceived as environments which support decision making. We support the view
that such environments can be readily provided for the subtask of model management by
hypertext systems. The different kinds of model knowledge can be captured within different
types of nodes and the relationships among these can be maintained by hypertext links.
In this paper we describe some aspects of model management where hypertext will have
a significant impact. However, plain hypertext is ineffective in dealing with the dynamic
nature of information in model management tasks where data is revised, models executed,
and reports are created on the fly. Dynamic domains require dynamic hypertexts. In this
paper we also study the requirements for dynamic hypertexts. These can be satisfied within
the class of generalized hypertext systems by using special hypertext nodes and links which
we describe. We explore different architectures to integrate MMS and Hypertext systems to
obtain HMMSs. This paper emphasizes the need for a shift to integrated Model Management
environments and proposes hypertext as an integrating technology.Information Systems Working Papers Serie
