The previous article is also produced under the needs of the user. I have never thought about it in this way (not there is no idea, just not paying attention to such a fine). It didn't make it so confusing before realizing it. Later I thought it was mainly because I didn't have a further analysis of users' needs. He proposed to crop the image local area, so requiring the software personnel to be more vague First, we must figure it out, what kind of image is cut, followed by the internal structure of the image, and finally how to implement the operation of the image. In fact, this will return to the software engineering, first understand the needs, and then do system analysis. . . . With demand, then how to do it, I think this is the system analyst or the project manager is going to do (I am afraid in China, I can't reach this requirement, just like me, one blue to the end!), Transforming user demand into a language that programmers can understand, how to translate, I think about the process as follows (this is a little experience of doing projects, not the theory of the book): 1, need to involve what kind of knowledge, For example, what kind of image or standard 2, use the program language or what is the development platform, such as the image operation section of the VC, with the top two foundations, the implementation of the demand is not difficult :) Many aspects of Dongdong stayed later and share it with you, I have to eat!
