Factory Pattern: Factory Pattern is a frequently used pattern. Classes implemented according to Factory Pattern can generate instances of one of a group of classes according to the provided data. Usually, this group of classes has a common abstract parent class and implements the same methods, but these methods perform different operations for different data. First of all, we need to define a base class. Subclasses of this class implement methods in the base class through different methods. Then you need to define a factory class that can generate different subclass instances according to conditions. After getting an instance of a subclass, developers can call methods in the base class regardless of which subclass instance is returned.
It can also postpone ontology instantiation until it is really needed. For an ontology object that takes time to instantiate, or an ontology that is too large to be stored in memory when not in use, we can postpone instantiating the object.

Visitor mode is to encapsulate some operations applied to a certain data structure. Once these operations need to be modified, the data structure that accepts this operation can be saved unchanged. Visitor mode is suitable for systems with relatively stable data structures. It reduces the coupling degree between data structures and operations acting on data structures, making the set of operations relatively free to change. The specific structure diagram is as follows:
