Hi all ranchers,

Yes, "Drop Table" could very well be considered a database refactoring.

Um.....could you tell us why "Drop Table" could very well be considered a database refactoring?

With refactoring, you could certainly normalize an already existing database, but there are a lot of other things you can do with refactoring, too (denormalizing it, for example ).

With other words, normalization is one goal in designing a database. Refactoring is about changing the design of an existing database, whatever goal you follow by doing so.

I wonder if you could tell me that is refactoring a kind of process re-engineering based on the database with some conditions such as performance?

Can I say an UseCase is a collection of stories.

I think that a Use Case could be a story or a collection of stories that describe the events and processes

Also an exception case is also an story?

I think that exception case could be a branch or a collection of branches for that story.
And the story may be better to be defined by EBP guideline
It seems that V model is the modern one, I have seen all SDLC pictures are cycle and chain. Does the concept remain the same for V model comparing with the traditional one such as cycle?
I think that it depends on the mechanism running behind, the memory allocation, the status of memory fragmentation...etc. I think that many conditions will be included when we want to know which one is faster.

Yes, when we develop an application for the bank transaction, it will become some tips for us..... I wonder why that situation did not happen in our real live.

My suggestion is that find and read a good Java book, stay here to ask some questions when you have and share what you learn. Of course, I think you are in right way

You can add some println function to print the result out when the loop run everytime. And also you can add the counter to know more clearly, the 1 time is.....the 2 time is ......etc

Hi Kevin
The sign = is equal to the mathematics = , for example
x=1, y=2
z=x+y //The sum assign to the varaible z, and z store the value of sum
then z=3
if x=x+y
then x=3 //The same idea of previous example.
why? In mathematics, x is not equal to x=x+y, you can think the variable x is a box that you can use it to do calculation.
And how about y=x=z=1? please think about it

I do not know too ^o^ as I just copy the answer given from TA and then smile
I think that only version 1 works
Version 1

Version 2

Version 3 (Original version) ambiguous one

Do the above three version work?
I wonder that is the program missing the base case?
thanks ^o^
