ASSIGNMENT TASK (40 POINTS)
1) Develop and test a Web services based application that meets the following requirements applying
SOA design principles.
a) Basic requirements and assumptions
i) The application should be developed using the .NET programming environment. However,
you are free to use any programming language you are comfortable with but supported by
the .NET development environment.
ii) The system to be implemented is a ‘CONVERSION’ service that can perform based on
user input and preferences, the following conversions: temperature (Centigrade to
Fahrenheit), distance (Kilometres to Miles), and height (Inches to Centimetres).
iii) The system should implement both forward and reverse conversions. (e.g., Centigrade to
Fahrenheit and Fahrenheit to Centigrade) depending on user preference.
iv) The system should be implemented as a complex service
that includes a controller/master
service that is responsible for interacting with the client application.
v) A response should be sent back to the client and displayed on the screen with all user
interaction through a GUI.
vi) Your design should incorporate SOA principles

The figure below shows a possible architecture for the system to be developed.

b) NOTE:
1) The client does not have knowledge of the individual web services. It must make
use of the services of the controller for consuming any web service.
2) ONLY
the controller has knowledge of all available web services.

Your submitted solution must comprise of a set of documents:
(i) VS2010 project files
(ii) A basic user manual including test data: input and output, and screenshots of the
working application.

E
XTRA CREDIT (5 POINTS)
