Design patterns for software development of the importance of self-evident, code reusable, maintainable, scalable is always the pursuit of software engineering! For me, a javascript person, it seems difficult to understand design patterns, and it may not even be used for Chettu only, with a small amount of interaction,

no difference, but the problems will be exposed in the development stage. Let's look at two basic design principles. [Simplified aggregation] The design principle of streamlining aggregation is undoubtedly the most important. Some Software Engineering Methodology books often guide us in UML business modeling,"No technical implementation issues need to be considered at this stage"According to this guiding p

I hate "design patterns" (probably because I learned Oo from OMT). Oo is actually compromised by design patterns. The idea of "Design Pattern" is that he first sets out a set of flowers and shelves there, and then teaches in a general way such as "How to get together with l

[WPF series] basic learning-WPF design patterns overview, wpf-wpfIntroduction The "Design Pattern" is something cool for programmers to pick up, And it truly makes programer of the beginner Design Pattern intoxicated. Too many experiences tell us that "everything must be done in an appropriate way and we must learn to

object respectively, they will callshowMethod to generate different execution results. The object polymorphism reminds us that "what to do" and "how to do" can be separated, even if a search map is added in the future,renderMapThe function still does not need to be changed, as shown below: Var sosoMap = {show: function () {console. log ('start rendering soso map') ;}}; renderMap (sosoMap); // output: Start rendering soso Map In this example, we assume that each map API provides a method namedsh

development, principles, Patterns, and Practices"in a book. The dependency reversal principle is defined as follows: dependency reversal principle (Dependency inversion Principle, DIP): Abstract should not be dependent on details, details should be dependent on abstraction. In other words, you want to program for the interface, not for the implementation. You can use high-level interfaces as much as pos

【Abstract]The principle of the design pattern is that the module should be open to expansion, but the modification should be closed. The module should try not to modify the original ("original", which refers to the originalCode) Code. So how can we expand? Let's look at the factory model "factory pattern": Suppose Zhongguancun has a hacker who sells pirated disk and wool film. We designed a "CD sales management software" for him ". Why should we

The term "Design Pattern" is widely used not only in C ++ but also in other computer programming languages. The famous Design Model Book head first has already sold well. "Big talk Design Model" also sells well. It's really hard for people who are engaged in computer programming to think about it. After learning a C ++

data type and string type into the dual pipeline of this link, to write structured data to a disk file, as shown in: 　 This is the major role of the link. The stream processing process by the stream processor must all have streams. If the streams processed by the stream class are classified, they can be basically divided into two categories: The first array, String, file, etc. This is called the original struct. Second, a stream of the same type is used as a link stream class, called a link pi

Reading this book makes it easy to understand and understand, so that you can quickly understand the design model. It is indeed a good book. This allows you to inadvertently understand and deepen Oo, as well as the advantages of the design pattern. In the purification process at, you can improve your understanding of t

modified, the data structure that accepts the operation can remain unchanged. The visitor mode is suitable for systems with relatively undetermined data structures. It frees the coupling between the data structure and the operations acting on the structure, allowing the operation set to evolve freely. The visitor mode makes it easy to add new operations, that is, to add a new visitor class. In the visitor mode, the related behaviors are concentrated in a visitor object, rather than scattered in

are three major ideas to improve performance: cache, splitting, and parallel. On top of the three ideas, there is another general idea: Find the performance bottleneck and try to optimize it.6. The idea of caching has been well discussed by Lao Zhao today. At each layer, there are cache Implementation ideas and solutions at each level, with advantages and disadvantages. It would be even better if we could talk about the common characteristics of the cache mode. It may be concluded that the CPU
