What is the logic of the sales model diagram?

The logic of the sales model chart is to arrange according to the specific sales, and draw the corresponding graphics from big to small, so that the data corresponds to reality.

Through subjective consciousness, with the help of entity or virtual representation, it constitutes an object that objectively expounds the morphological structure (object is not equal to object, not limited to entity and virtual, plane and three-dimensional).

Model ≠ Commodity. Any object is a model in the process of research and development before it is defined as a commodity. When the model and specifications are defined and matched with the corresponding price, the model will be presented as a commodity.

Broadly speaking, if one thing can change with another thing, then this thing is a model of another thing. The function of the model is to express the attributes of different concepts. A concept can make many models change to varying degrees, but only a few models can express the nature of a concept, so a concept can change the expression form of the nature by quoting different models.

When the model is associated with things, it will produce a framework with attributes, which determines how the model changes with things.
