A new model for the development of information systems
thesis
posted on 2010-11-23, 11:26 authored by Shwan MoubarakThe most commonly used systems specification and design techniques in commercial
computing are described and compared; Information Engineering as proposed by James
Martin, A Framework for Information Definition-Muitiview proposed by Wood-Harper et al,
Real-world Modeling as described by Jackson, Structured Analysis and Design as In Demarco,
Yourdon and Constantine and Output-Oriented Structured Requirement Definition proposed by
Orr. In addition, system prototyping is discussed, including the role of prototyping in large
software development projects and as a tool for the design of human-computer interfaces.
Other areas described and discussed include decision support systems (DSS) and knowledge
based management support systems. The context is in the design and development
approaches for DSS, prototyping for DSS, expert system for DSS and the integration of DSS
and information system. The design and development of human-computer interface is also
discussed in relation to user Interface complexity and adaptive interfaces. Further, the
important issue of user involvement and support within the development process Is discussed.
Thus, weaknesses of current approaches to the system development process are identified and
a new model for the development of information system is proposed. In proposing the model,
data and functional analysis structured method and methodology for decision support systems
(DSS) development is presented including guidelines for the development of knowledge based
DSS. The new proposed model is put to test in the design, development and implementation of
large integrated commercial systems including DSS. Results and discussion on the use of the
model is reported with special consideration to the users' and developers' view of the model.
Finally the objectives of this research program are examined in relation to what has been
achieved during this program of research. The prospect of using the model for the
development of information systems are concluded with references to current and future goals.
