Maybe I have read the previous articleArticleAfter I listed that part of the information, I still have many friends who do not know about the domain-driven design.

On the system architecture design of the biggest problem, in fact, is the allocation of responsibilities, allocation of reasonable, the implementation will be very flexible, the contrary will make the structure is very chaotic.The life cycle of software can be summarized into four basic processes, analysis, design, implementation, testing, of course, this is only the most sketchy expression.
