The complete model describes the whole system. (Rumbaugh, Jacobson, & Booch, 2005,
p. 635)
The personal financial planning process can be supported by financial Decision Support
Systems (DSS). In general, a Decision Support System can be described as follows:
Definition 6: A Decision Support System (DSS) is an interactive, flexible, and adaptable
computer-based information system, specially developed for supporting the solution of a nonstructured
management problem for improved decision-making. It utilises data, provides an
easy-to-use interface, and allows for the decision-maker??™s own insights. (Turban, 1995)
Continuous interaction between system and decision-makers is important (Briggs, Nunamaker,
& Sprague, 1997). Interactive decision-making has been accepted as the most appropriate
way to obtain the correct preferences of decision-makers (Mathieu & Gibson, 1993;
Mukherjee, 1994). If this interaction is to be supported by a Web-based system, then there
is a need to manage the related techniques (or models), to support the data needs, and to
develop an interface between the users and the system. Advances in Web technologies and
the emergence of the e-business have strongly influenced the design and implementation of
financial DSS.
