thanks.for sugesting google.actually i just want to disscuess those..if u dont knw ..does not matter.

He knows the answer - but he is right to say that the questions look like homework. If you want to discuss these subjects then you might like to phrase the questions in such a way that it looks like you are discussing the subject out of genuine interest rather than as an answer to a homework question.

I'll do your homework for $50 a question. Google is cheaper.

I want to know the answers of these qustions are these true or false.....in both cases provide justification...thanks (a) testing of non web based software system is completly different from based software system.? (b) design phase of object oriented system need more cost and effort than design phase of functional oriented system? (c) message passing features of object oriented paradigm play an important role in effecting effecincy of object oriented system? (d) maintanance of file based system is cheaper in terms of time and effort than data based system.?

Yes. One you test over the web, the other you don't.
rao raja wrote:
(b) design phase of object oriented system need more cost and effort than design phase of functional oriented system?
No. An object oriented system doesn't need much design you can just get stuck in and code away. A procedural based system needs lots of planning and design to decide on the properties and methods of all those procedures!
rao raja wrote:
(c) message passing features of object oriented paradigm play an important role in effecting effecincy of object oriented system?
No. All object oriented systems are pretty useless at passing messages. This forum is an object oriented system and look at how craply most messages are passed here? (See OP for evidence)
rao raja wrote:
(d) maintanance of file based system is cheaper in terms of time and effort than data based system.?
No. File based system have lots of files, database systems usually only have one database. One vs many, easy answer! That'll be $50 please. PS If google gives you a different answer to any of these its lying!

ROTFL - of course I *know*. But, if you want discussion, you need to lead off. If you want homework answers, you're in the wrong place.

The reason I didn't answer is, if it's his homework, he's not going to learn anything by copying your answer, now is he ?

Defining testing? As a general concept, testing is making sure something works as specified.
rao raja wrote:

Again design is a bit of a generalization. A more detailed design is going to cost more time and resources than a top level design.

Depends on who is doing it and who built the file system. I've spent many a hour fixing flat file based systems, where as something like SQL Server has lots of tools alreafy built in.

Testing is a waste of time, because you'll never discover all the problems. It's much more efficient to ship an untested product and have your customers report the problems.

Design is expensive and pretty much worthless. What you want to achieve is the longest development cycle possible due to continual rewrites so that you can continue drawing a lucrative salary and the venture capitalist funding your company can continue writing off business losses on his taxes.

OOP message passing is archaic technology. Current trends are moving toward quantum principles in which the receiver gets the message before the sender sends it.
rao raja wrote:

Definitely. A flat file based system is much cheaper to maintain since you don't have to worry about indexing, performance, optimization, clustering, distributed servers, etc. All you need is a big hard disk, and hard disk prices are plummetting. Just last week my client discovered he could buy a 400GB hard disk for the same price that a 320GB hard disk was selling for six months ago.

There are no right and wrong answers to those questions if you give your reasoning - they seem pretty subjective to me.
