In the previous article, we discussed what a schema is. In fact, these basic concepts are very important for architecture, and most people think they are aware of the concepts they are accustomed to every day, but in fact they are subconscious and not active. For example, "What is a table?" "When I do training, I often take this example to ask you, answer all sorts of strange things."
