3.0 System Development: During the
development period of the System, it is
very important to generate sufficient
information on the requirements, which
would l;iye enough input to the dc;.signer

2.0 An approach: System study involves
Analysis, Design and Postulates. It is a
fact-that the prediction of Performance
of a system is not feasible during its
hypothetical state. One way is to build a
Proto-type. It is known that analysis
gives the operational aspects, design
conforms of meeting of the system-
requirements, and test and evaluation
brings out the behavioral portion. Hence,
it is preferable to have a Proto model
that gives the system boundaries,
identifies the entities, attributes and
activities of the system. The data shall
provide the attributes and the
relationships of the activities.

The advanced technologies in the oompuJr science have given us opportunities to include sophisticated
