Demand analysis is the last phase of a software-defined period, and its basic task is to accurately answer "what the system must do." ”

turns of the analysis, and can not only choose a time range of twists and turns, Select at least one curve with more than two twists and turns. If you select only one twist, after automatic association, you will find that many items have a correlation of 100. This analysis does not make sense, because only one of the twists and turns of the time range is too small.

discussion on monitoring and analysis of key indexes in software performance testing
first, the software performance test needs to monitor which key indicators.
The purpose of software performance testing is mainly as follows: three.
Ø evaluate the current performance of the system to determine whether the system meet
limitations, database access performance settings, etc. often become a constraint on software performance, but these factors are obviously not the user's most concern, we need to pass a number of settings before testing to minimize the impact of these factors.
In addition, the user is more concerned about which part of the system performance situation will also affect the scope of work. If the link is a new system, and some of the link is already a m

The most difficult part of developing a software system is to accurately describe what to develop. The most difficult conceptual task is to compile detailed technical requirements, including all interfaces for users, machines, and other software systems. At the same time, this
