Dictionary entity in Database Design

Source: Internet
Author: User

Today, during the analysis, I found something that I often encountered before. I think it is necessary to put forward it specifically. This is called a dictionary entity.

I dare not say how to define this entity. What I want to talk about is how to distinguish it:

  1. This entity does not depend on any other entity
  2. This data can only be used as the basis for selecting other data, not as the selected object.

For such entities, it is necessary to list them separately. In engineering practice, it is usually a bridge between coding and database design.

You are welcome to discuss it in depth!
