I didn't find that. Which edition, which page? (Or even: which book?)

Analysis is about investigating the problem - making sure that you understand it, and therefore solve the right problem.

Design is about creating a solution to the problem.

Did that help?

Design is just creating conceptual solution to the problem . not the implementation .

That could be true, depending on your definition of "design". Others' definition for the word "design" might very well differ from yours. After all, the source code is not the implementation of the solution, is it not? Isn't it correct that the source code is not what the computer is executing? It's not even the bytecode that's the implementation. The computer executes machine code.

Source code is just as much "design" as a UML diagram is, for example. It's just design on a lower, more concrete level.

You might be interested in checking out some of the hits Google provides for "the source code is the design".

You might want to consider questioning the concept of analysis and design phases. See Phases Examined for a discussion.

I didn't see anyone mentioning *phases*, but even as a preemptive strike, this is always a good reminder...
