The building code stipulates that the bedroom window should be at least 30 inches high, 20 inches long, so that in the event of a fire, the person can pass; The yellow seat on the bus is for the old and the sick, and the child is often said to be free, but it must intervene for safety. These are the principles of life that need to be obeyed. When it comes to architecture, does it need to follow some

Web Infrastructure Design Principles Classic paper "Architecture style and web-based Software Architecture Design" guide

1. Overview Dr. Roy Fielding (see Personal homepage) is the main designer of the HTTP and URI protocol issued by the IETF. HTTP and Uri are the two most important web infrastructure protocols, so Dr. Fielding is one of the founders of the Web architecture. In addition to academic excellence, Dr. Fielding has been involved in the design and development of many Open-source software. He was the developer of Libwww-perl, one of the world's earliest HTTP

Design principles in Architecture Interface Separation principle (ISP)-Java Development Technology-experience the beauty of design patterns and algorithms in architecture

: Interface high cohesion is internally highly dependent and isolated as much as possible. That is, the method of internal declaration of an interface is related to a sub-module, and is required by this submodule. Interface design is limited: If you fully follow the principle of interface separation, there will be a problem, that is, the design of the interface will be less and less, so that the number of interface increases, the complexity of the system increased suddenly, rather than the

the same result, that is, the service is idempotent. Service idempotent is sometimes natural, such as setting the user's gender as a male, regardless of how many times it is set, the result is the same, but for operations such as transfer transactions, the problem becomes complex and requires information such as transaction numbers. For service invocation validation, only valid actions can continue. Study Note 6: The core Principles and

Design principles in architecture open and close (OCP)-Java Development Technology-experience the beauty of design patterns and algorithms in architecture

Opening and closing principle OCP (Open for extension,closed for modification). The core idea of open and close principle is that an object is opened to expansion and closed to modification. In fact, the opening and closing principle means that changes to the class are made by adding code rather than altering the existing code. In other words, once the software developer writes out the code that can be run, it should not change it, but to ensure that it can continue to run, how to do this? Th
