A message board for scientist discussion
A computer scientist works on di erent research areas. When some chal-
lenging problem is solved the scientist write a formal report (a paper) where
all ndings 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 ndings. 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
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-

The student should describe the protocol used to implement the message
board system. More specically 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).
