A message board for scientist discussion

A computer scientist works on different research areas. When some chal- lenging problem is solved the scientist write a formal report (a paper) where all findings are carefully described. The paper can be submitted to a con- ference where a committee of experts reviews and criticises its technical content. High quality papers are selected and scientists are invited to meet and give a presentation of their findings. A conference is great opportu- nity where a scientist can present his paper to other scientists and receive feedback from them.

You are asked by the conference organiser to build a message board system. The system should allow a scientist to open a discussion about his research topic. Each research topic contains a set of messages posted by the scientists.

In the following the main functionality of the system are described:

  • each scientist can create exactly one research topic
  • each scientist can see all research topics created by other scientists;
  • each scientist can read all messages posted on a research topic;
  • each scientist can post a new message

Each message will be posted together with his writer and the date. In the following there is an example of a research topic and some mes- sages:

The student should select an appropriate architectural style in order to design the message board system. Once the architectural style is selected the student should provide a component based diagram. (25% of the total marks).

The student should describe the protocol used to implement the message board system. More specifically s/he should describe all messages exchanged among components and all rules of interaction (25% of the total marks).


The student should provide the system architecture (5% of total marks) and the reason for the selected architecture. S/he should also provide a java implementation of the message board (45% of the total marks) Note: If we have 5 scientists we can have a maximum amount of 5 research topic (one for each scientist).
