How old are you ? if you dont know the answer then there is no harm to respond ....its a decency. you should know even if anybody post home work question also , then there is a way to answer ...how ? providing the relevant links/ resources .

I know the answer, because I googled for "non functional requirement" and got 31000 hits. The first hit, linking to Wikipedia, explains it quite well. > BTW, this is not a homework and i am asking about the meaning of that > keyword. .....that keyword is bit misleading .....when it says , non- > functional ....does it want to say , non - business logic ? > again ..thats also a vauge idea......this is not understandable .....i > am just aksing the interpretation of non-functional in a design . Well, that makes it more clear why you asked your question. But you should have said that in your original post, in order to get more helpful answers in the first place. > ok, suppose, i have a software design ...say ,this software would > enter some information via browser to the DB .....what could be the [quoted text clipped - 8 lines] > Remember , we are in a learning process ....and we are earning > knowledge.

I didn't say whether I did or didn't share his opinion. Good point. OK, Thomas correctly expanded the acronym, and it is my opinion that gk should do their own homework and not ask for the answers on a plate.

If it answers your question, then you don't need to ask elsewhere, you get a happy glow of achievement, and you have sharpened your skills: not bad for ten minutes with a browser.

It's a bit like M$ - the more you know, the more you are trapped in its fiendish webs of treachery. SignatureC.

It is somewhat insidious too, <http://www.google.com/search?q=google+is+your+fiend> produces the response.. "Did you mean: 'google is your friend'" I would almost have been prepared to click 'of course I mean google is my best buddy' if they offered such a button, just to keep the search engine happy, and hopefully keep my name off it's report lists to US federal agencies. Or is it all just 'Googlespeak', in action? ;-) Andrew T. >> for the answers on a plate. Google Is Your Fiend. > ^^^^^ > > I'm assuming that was unintentional, Interesting.

We might learn as a result of the discussions, but that is 'above and beyond' the groups's stated purpose. >....and we are earning knowledge. You might 'earn' that knowledge by starting a thread more along the lines of.. "whats the meaning of "non functional requirement" in a design ? My research has led me to understand ... insert current understnding here ... but I do not understand ... insert specific questions here ... " OTOH, adding something like.. "please provide an example" is more likely to provoke the response "please provide cash" Andrew T. > if you have a little bit of sense , then you could easily understand > that this is not a homework. I think you would help yourself if you put a bit more thought into /how/ you ask questions here. I remember that this happened to you once before (the "Which is not allowed in EJB programming ?" thread in September last year). The problem is that you phrased your question in a way that made it sound /exactly/ like a lazy student trying to get someone to do their homework for them -- and if you do that, then no matter how unfair the judgement may seem to you, you will get this kind of response every time. FWIW the Wikipedia acticle (that you've already been pointed to) seems quite reasonable to me. If you've already read it and it doesn't help, then by all means say so, and ask again. Anyway... > ok, suppose, i have a software design ...say ,this software would > enter some information via browser to the DB .....what could be the > functional and non-functional thingie here ? Some examples of functional requirements: What data is to be entered ? What language(s) are the data-entry screens in ? What do the data-entry screens say ? Are uses required to log in first ? How ? Some examples of non-functional requirements: How quickly must the database respond ? How many users can the system support at once ? How much downtime will be tolerated in any one year ? Some examples which are (I think) borderline between functional and non-functional: How often is a backup made ? What security provisions are necessary ? Where are logfiles written and what do they contain ? How does the system report failures to the admin staff ? -- chris On Feb 12, 10:03 am, "Chris Uppal" <chris.up...@metagnostic.REMOVE- THIS.org> wrote: > gkwrote: > > if you have a little bit of sense , then you could easily understand [quoted text clipped - 37 lines] > > -- chris Excellent answer ..criss.i was looking for something like that ......you have pointed out some points for non-functional requirements which seems a kind of performance tuning. can i think it as "some requirements" which is outside of the java coding ? for example , RAM size, DB preference etc etc ...can we call these also non-functional requirements ? Agian , thank you for such a beautiful answer. > for example , RAM size, DB preference etc etc ...can we call these > also non-functional requirements ? I think it would be more accurate to say that non-functional requirements (such as speed and reliability) would drive the system architects' decisions about those questions. Having a certain amount of RAM is not a requirement /in itself/ (not even a non-functional one); the RAM is just there so that the system can support <some number> of users (or whatever). It's the "must support <some number> of simultaneous users" which is the requirement; the choice of how much RAM to install is part of the overall system design and is chosen to /satisfy/ the requirement. -- chris > whats the meaning of "non functional requirement" in a design ? > > please provide an example http://en.wikipedia.org/wiki/Non-functional_requirements Or my favorite: http://www.google.com/search?q=what+is+a+nonfunctional+requirement Free MagazinesGet these publications absolutely FREE for up to 12 months.
