Abstract:
Existing design methods used for developing webcentric
systems are mostly adapted from methods for
designing traditional software systems. Web-centric
systems however differ from traditional software
systems, in terms of both organizational and technical
characteristics. Effective design methods for webcentric
systems need to address these characteristics
specific to web-centric systems. This paper proposes a
design method for web-centric systems. The de-sign
process comprises three steps: prototyping,
information modeling and sys-tem architecture design.
The method is differentiated from existing design
methods in that the design process commences from
user interface prototyping. Information modeling
activities are further enhanced in this method. To cope
with the complexity of web systems, each design step is
partitioned into both structural modeling and
behavioral modeling. The design method is illustrated
by applying the method to the design of a commercial
web application.
