In fact, the focus of this blog is not to introduce a three-tier architecture, but to focus on MVC and help understand MVC. After studying for so long, MVC finds that there are many misconceptions about it, and today it's time to sort out the MVC.MVC is Model-view-controller, which m-v-c each representative of what, I think even if I do not list everyone also know the chest. Because too familiar, as we have learned three layers of

IntroducedMVP This architecture has been the focus of discussion in the Android development community, and everyone has their own analytical understanding of the controversy. Until Google officially releases a project built with the MVP structure on GitHub. It feels like it's time to analyze.Introduction to the MVP architectureThis is not the focus of this article, so excerpt from Li Jiangdong's blog postIntroduction to the MVP architectureFor an appl

In terms of what a pattern is, the word from architecture is defined in this way: "Each pattern describes a problem that constantly repeats around us and the core of the solution to that problem." This way you can use the program over and over again without having to do repetitive work. " The key to the pattern is the reusability of the pattern, and the repeatability of the problem and the scenario that leads to the solution.Perhaps the Internet produ

Today, my colleague asked me what is the use of web service in the system? What is the difference between it and the general direct writing on the client? What are the advantages? It is really interesting to answer this question. Since I have asked this question, it means that there are some preconditions for not reaching an agreement. It is easy to explain the technology itself. Therefore, we should first clarify the background of recommending the use of the SOA

High concurrency Server Architecture Evolution of large website architecture Three server requirements: High Performance: rapid response to a large number of requests High Availability: uninterrupted, automatic failover occurs, which is called fail over (Failover) Scalability: Cross-machine communication (TCP) In addition, any network system structure can be abstracted into a C/S

Recently, the company requested that the architecture of a product be changed from two layers to three layers (the reason is: For security review, a three-layer architecture is required because the database port is only open to the server ), when I heard it, I fainted. The initial architecture of the product was three layers. Later, due to various requirements du

In the technical documentation, we often find that topology, architecture, and struct are not strictly differentiated. Sometimes we can see that a topology becomes a pure echure, and sometimes a struct becomes a pure echure.From a rigorous point of view, how should we define and distinguish them for correct use? My personal understanding is as follows: 1. the focus of topology is network deployment, such as the distribution of data centers. architechu

Advantages and disadvantages of C/s architecture:Advantages1. Because the client is designed independently, it can realize the personalization2. Because the client needs to be installed, it can not need to be installed and loaded repeatedly3. Because the client is independently developed, it has the ability to design the client securely4. If you encounter different operating systems, you need to develop a set of clients for different operating systemsDisadvantages1. Because the client is not req

The last section of the "large-scale Web site Architecture Evolution", today to talk about the structure of the model, what is the model? Each pattern describes the core of a problem and problem solution that repeats itself around us, so that you can reuse the program over and over again without having to do repetitive work, and the key to visible mode is repeatability.The goal of the Web site architecture
