GOF "design pattern" is described in the strategy mode:
Define a series of algorithms that encapsulate them one by one and make them interchangeable with each other. The strategy mode allows the algorithm to vary independently from the customer who uses it.
The strategy model is based on the following principles:

Windows File Association and open method list-modify registry strategy and file association registry strategy
Here are all ways to modify the registry. After searching for the Internet for half a day, some of them only have the method to add file associations, but they have not been added to the open method list. Some have the method to add files to the file list, it is used with the control panel-> folder
Webpage color strategy (white) and webpage color strategy
White physical brightness is the highest, but it gives people a cold feeling. As the color of paper and wall in life, white is the most commonly used webpage background color. Under the background of white, most colors can achieve good performance. White gives people the feeling of being white, bright, pure, objective, truth, simple, holy, just, brig

1. What is Reg?
The reg file is actually a registry script file. You can double-click the reg file to import the data to the Registry. Using the reg file, we can directly modify the Registry. Its registry operations are not restricted by the Registry Editor. Therefore, the Registry Editor is more powerful and flexible. In addition, the reg

Vim's learning curve is quite large (see the learning curve of various text editors). Therefore, if you see a lot of VIM command classification at the beginning, you will lose interest in this editor. The following article is translated from "Learn Vim Progressively". I think this is t
JS and design pattern ------ Strategy pattern StrategyI. general summary 1. I talk about the policy mode, also known as the algorithm cluster mode, which defines different algorithms and can replace them with each other, this mode makes the algorithm changes independent of the customers who use the algorithm. The policy mode is similar to the factory mode. The policy mode is relatively simple and easy to understand, and can be switched freely at runti
Strategy Mode:
Define a series of algorithms, encapsulate them one by one, and they can replace each other. The strategy mode enables the algorithm to change independently of the users who use it.
Specifically, key features of the policy model include:
Intent: You can use different business rules or algorithms based on the context. Problem: the selection of the desired algorithm depends on the user who send
9.1 informatization strategy and enterprise management strategy
Different enterprises have different focuses on their business strategies in different periods. Therefore, the demands for informatization vary at different stages. If the enterprise's strategic focus is on product upgrades, the application of CAD, PDM, Capp, GT, GAM and other information technologies becomes more urgent. If the enterprise fo
