Principles of Design Patterns: Programming for interfaces the role of the factory model: A. In the design of an application, create or unify the creation of objects in one place (spring) B. You can add objects directly without changing the application, while also facilitating the maintenance of objects. type of factory pattern: A. Simple Factory B. Factory methods C. Abstract Factory Wedge: Say the Northeast boss home has three cars, Mercedes-Benz, BMW, Blue Lamborghinis, hired an experienced

know how to write software and how to implement it, the entire erp process is unclear. Well, we have to look for a consulting company. Well, after we find Deloitte, Deloitte says, "How do I do software, I can guarantee that the software can provide you with an erp system. Example: The production of automobiles can be seen as a builder model. The mass production of Audi and Satana cars is as follows: Code Design: Create Car. cs First: 01 public clas

First, what is abstract Factory modeAbstract Factory mode is intended to provide an interface to the client to create product objects in multiple product families, and the use of abstract Factory mode also satisfies the following conditions: There are multiple product families in the system, and the system can only consume one family of products at a time. Products that belong to the same product family can be used. 　　Product families: A family of products that are associated w

The simple factory model is one of the factory models. There are three factory models: the simple factory model, the factory method model, and the abstract factory model, that is, all object creation tasks are handed over to the factory. From the simple factory mode to the abstract factory mode, the abstract level gradually increases. The factory model consists of three parts: the factory role, the abstract Product role and the specific product role. The factory role is the core of the factory m

My understanding: replacing a model with a factory method for new operations. The factory method encapsulates the new methods of several associated classes, and does not require new multiple times for each instantiation of these classes, only the corresponding methods of the factory class are called to instantiate the classes.Combine simple examples and UML diagrams to explain the simple principle of Factory mode. first, introduction saying ten years ago, there was an outbreak, His family had
