In the event of a significant refactoring of entity relationships, these can be modeled visually, verified, and then imported into your application, ideally avoiding any programming changes.
还存在其他方法和形式，但是本文将集中于实体关系建模技术，因为此项技术与稍后将描述的技术更密切相关。
There are other approaches and forms, but this article focuses on the entity-relationship modeling technique because it is more closely related to the technologies described later.
