Hi,

Can anyone give me the architecture details of GRE exam online exam
simulator.

In this exam, the questions will be popping up very randomly..
with varying difficulty level...

i want to know, whether this kind of simulator, makes use of any
database
or does it makes uuse of the flat file, to store the questions..

please clarify my doubts..

Thanks and Regards
HariKiran

If you have a stable set of exam questions, there is no reason to
use a database. A flat file in the XML format is editable and
flexible. Unless you have a truly monsterous set of questions,
keeping the entire set in memory as a DOM is entirely feasible
and so much simpler than a separate database.

I downloaded a sample exam for the "GRE EXAM" and ran it.
It uses macromedia flash and does not pop-up anything, it goes
from question 1 to 2 etc to 37 or whatever.

If you are asking about what to do in java, I would recommend a
List such as.

static List<String> sArray = new ArrayList<String>(32);

Hi,

The actual requirement in the project is:
1) we have a huge collections of questions for example 30000.
2) the examamination goes for 120min,
3) In an exam, totally 150 questions are givn to the student.
4) those 150 questions are given randomly and it should not repeat.
5) In My application, i want to store the students results info as well
6) That application should give me the report on my performance, after
2 to 3
exams.
7) i am not using any servlets, and any servers, it is a complete
standalone application.

please tell me for this kind, DB or flatfile is a suitable solution.

Thanks and Regards
HariKiran
