Design and Implementation

Title: Forum Interactive Message Board (FIMB) Researchers work on different sites and when faced with some challenging problems they tend to discuss them amongst each other. You have been given the task to design such an FIMB to reduce cost of traveling and the needless creation of traffic that copying everyone on an email creates. You have been contracted to design and build such a system that would allow researchers to open a discussion about their own topics and for others to contribute as they wish. The researchers envisage the system according to the following criterion: • each researcher may post exactly one research topic • each researcher may see all research topics posted by other researchers • each researcher may read all messages contributed by all researchers on a particular research topic; • each researcher may post a new message to contribute to the discussion on any of the topics posted in addition to the following: • each message posted must include the writer’s name, time and date, i.e., Research topic: Intrusion Detection Systems Posted by: John [22/10/11 14:00] John wrote I am building a new IDS based on neural networks. …………….Comments ………….?

Design - Select an appropriate architectural style for your FIMB design. - Provide a component based diagram. - Describe the protocol used to implement the message board system with emphases on all messages exchanged among components and rules of interaction.
