 3.mysql in a table in the mysql database have an entity (entiy / pojo / domain) with its corresponding, similarly mango in the collection (table) there will be an entity with its corresponding:

// Create a table following order:

public  class ShopMongoOrder { 
    @Id    // after affixed Id annotation, generating a collection of objects mongodb, annotated fields are posted primary key is unique, not repeated
