well i am design a stor room application
could you all geven me advice
how to do that.
First write down a description of the problem your application is trying to solve. Poor problem definition, IMO, is the major reason why most projects are never completed.
Then write down a description of what a solution should be able to do.
From these descriptions, pick out the nouns, verbs and relationships between your nouns. This should tell the important classes, methods,interfaces and class relationships required.
I suppose you have already decided which language you are going to use for this?
