=> how to create db connection
=> explain your project
=> functionality and flow of project
=> How was testing done give some scenario
=> how was project implemented.

Student -8

- describe the project. asked some questions about the reports generated.
- what is DFD? Draw 0 and 1st level DFD.
- can u see the entities and attributes in DFD.
- what are entities? types of entities? set entitiy?
(well I forgot about set entity)
- why didnot I use EJB? I replied I don’t have all the concepts clear in case of EJBs. I know one should not give answer like this but my mind got totally blank.
- wite syntax for connection setup.
- what is active-x control(didn’t do full justice with this one).
- difference between servlet class, normal java class and container class.
- which testing technique have you used? what is white box testing? which technique under white box testing?
- which case tool I have used for testing? this question doomed me. because I had not used any specific case tool.
Student-9
Some questions are:1) No:of modules and their names
2) SRS

1.    Personal questions: -
first couple of questions were about self intro and stuff
2. Explaining the project: -
the examiner asked me to explain my project
3. Questions regarding the project: -
like what are normal forms, up to what level is the project normalized, paradigm applied, DFDs, write an SQL statement etc. (Nothing in depth about the project… so after doing the whole project it sounded a bit too simple actually… being asked about the basics)
4. Questions that are distantly related to the project
like what is security, what is hacking, what do u understand by firewall, how do you set up a firewall and what does it do

5. Questions not related to the project:-
like wht is the protocol for file transfer over the internet and what is TCP –IP… wonder why those questions were asked coz my project wasn’t a web based application.

What is Data Dictionary.
Explain Testing and its methods.
What is Normalizations and its levels.

It was my experience and i also want to share my friends experience. He asked the same questions to other and some more questions such that

What is Code Efficiency.
What is Robustness.
Explain any Cost Estimation Model like COCOMO and what are their inputs.
Explain some SQL Queries.
Some Part of Coding.

Technical questions were on following
-Explanation of DFD,Flowcharts and diagrams. Some students were asked to draw it again on paper
-Explanation of coding (randomly selected) or writing again on paper
-Questions on SQL basics like Queries, stored procedure,trigger. Asked to write example
-Testing fundas. Asked to write test cases and test plan for given example
-Client – server architecture and how it is implemented in project
-If students got any suggesstions during approval , studnets were asked how they improved and implemented the suggessions
