Web quest: Find a range of five sites each offering different business options: online shopping, electronic payments, database access, WAP sites for mobile phones. Key words for your search engine: M-commerce, T-commerce and E-wallet.

 

You may be interested in building Web applications, or in network design. This subject has you researching and working with using some technologies for designing and/or building client server applications. At the same time, you are asked to consider examining the big picture – how each application contributes to the large scale needs of an organisation – planning, policy, competitive edge, knowledge management and the need for secure electronic transactions. You may want to do some research into Object-oriented UML design work and project management that is needed for e-business applications, or into the use of extreme programming (XP) methods. One useful approach is to use rapid evolutionary prototyping.
