Realtime(Synchronous) Chat service

This is the chat service where users can chat in a Chatroom(one to many) and also can send a message to a particular user (one to one chat)

In this pic the users can send message is Chatbox..
on the ryt side, text field show the online users!








in this pic... we can see that sudipta is sending the message to me..NOT IN CHATROOM.

it is the example of one to one chat!



Now we hav to implement tha designing portion of chatroom! where users can use our chat application like Gmail or facebook chat!!

ASYNCHRONOUS MESSAGING SERVICE

**** ASSUMPTIONS:

• cookies are enabled in the client side. ( this assumption could have been done away with by using encodeURL(..)

EXAM management... variable number of questions for each exam...

For the exam management system...

I have made an observation:

The number of questions for each question may vary...

So, I wanted to use something like an array...
but thats isnt possible in databases it seems.

so,
according to the srs...
we have an EXAM table.. which contained the arr_questions and arr_answers.

we could do one thing:

leave out the arr_questions and arr_answers from the exam table.. ( the other attributes remain intact)

we'll use another table called:

QUESTIONS( question_id,exam_id, question,answer)

hence, exam_id will reference the EXAM table...  question_id will be the foreign key...

howzzat...??
