Redis has always been a component that I want to study well, but previously limited to work scenarios that didn't really make sense to use. But at the moment, Redis acts as the primary cache component to buffer server pressure. Therefore, this sequence is mainly based on the actual work encountered in the design and development of the redis, and gradually, in order to be rational, there is no misleading anyone.Before I begin, I will share the relevant content mainly from the following points:1.

Demand must be ready before you begin to construct a thing. Much of what is described earlier in this book is how to know these requirements and ensure that they are correct.The diagram in the book is very concise and tells us the relationship between demand analysis and system analysis in the development process. In the early stages of development, or in the preparation period, demand activities dominate, we need to make a lot of detailed analysis of the existing information, to find out what o

The growth rate of the object type is fitted by least squares bas
