At the beginning, the author explains why modeling is required. Next, he describes four key structural analysis model tools, which are well-known.DFD(Dataflow digoal),ERD (entity relationship digoal),STD(State Transition Divisor),SC (structure chart) The following is a simple description. 1. DFD (dataflow digoal) DFD diagram is used to describe the

underlying things affect the performance of the application in unexpected ways, such as the inability of some programs to take full advantage of the cache, resulting in degraded performance. such as unnecessary calls to excessive system calls, resulting in frequent kernel/user switching and so on. Here is just for the following content of this article to do some foreshadowing, about tuning there are many things, I do not know more than know, I hope we can learn together progress.The Performance
