ORM Basics

Let's first introduce the basic concepts of Vona ORM:

1. Entity: Defines the basic fields of an entity
2. Model: Defines the relationships between entities and provides methods and tools for operating the database. The methods provided by the Model can automatically infer the required type structure based on the relationships of entities
3. Migration and Changes: Used for database schema changes and data initialization

These basic ORM concepts were explained in the introduction to the API. See:

• API: Entity
• API: Model
