Seven Principles of Software Design The general principles of design patterns are as follows: 1.Open-closed principle ):A software entity should be responsible for extended development and should be closed for modifications. when designing another module, the module should be extended without being modified. in other

General principles of design pattern adherence:1. Open-Close principle (open-closed Principle, OCP): a software entity should be developed for expansion and closed for modifications. The point is that when designing a module, the module should be extended without being modified. In other words, It should be possible to change the behavior of the module without having to modify the source code, and to extend

Software design requires a Historical View Wu Yu Taiyan Network Studio During the National Day holiday, I went to visit Zhao zhouqiao, which is described in our elementary school textbooks. The arch bridge that has existed for more than 1400 years. To be more precise, Zhao zhouqiao was established in 605 AD and was established in 1407. In the meantime, it has experienced 10 floods, 8 wars and multiple eart

This is als

determine the abstractions that are not obvious and describe these abstractions.2) determines the granularity of the object.3) Specify the object interface. An interface is a collection of all the operations that an object provides.4) Describes the implementation of the object. Programming the interface, not the implementation.5) Use the reuse mechanism. The combination of objects is preferred instead of class inheritance.6) The structure of the associated run time and compile time.7)

Schlumberger pipesim 2011.1.1 oilfield Pipe Network Software Pipesim describes the fluid in the black oil model and component model. The black oil model can be used for Calculation and Simulation of three phases: oil, gas, water, gas-liquid, gas-liquid, and single-phase liquid.The component model can be used to simulate the calculation of hydrocarbons with different chemical components.The biggest feature of pipesim is the integration and openness of

In 1973, Peter Freeman, an AmericanArticleAutomation software design has the assumption that, if there is such a machine, when we tell it what software we need, it will immediately meet our requirements and automatically generate what we needProgram. From the user's point of view, the automatic software

inflexible, the demand analysts always want to understand all the requirements of users. After understanding the requirements, we assume that all the requirements are understood and then design and code them, as a result, the software cannot handle new attributes flexibly in the future. To solve this problem, we believe that using user configuration and templates can not only reduce the time required for

During software design, the degree of detail of analysis and design, as well as design deficiencies and transitional design problems are usually encountered. Generally, the purpose of design is to grasp the degree of
