Support batch assignment, and the $fillable attribute needs to be defined in the model to ensure security; 4. Provide strong relationship support, such as one-to-one, one-to-many, many-to-many, etc., and you can access the associated data through method calls; 5. Integrated query constructor, where, orderBy and other methods can be called chained to build queries; 6.
