Business expansion: three-tier architecture and three-tier architecture 1. What is the three-tier architecture first to see the title? The three-tier architecture is actually: ① Presentation layer: receives user input and presents the output to the user, And access security verification, and correctness of the input d

thinkphp3.2.2 Common class architecture problem analysis, thinkphp3.2.2 architecture In this paper, the common class architecture of thinkphp3.2.2 is analyzed. Share to everyone for your reference. The specific analysis is as follows: Before 3.13 Many projects all use the front and back common class, under Lib/action creates the baseaction as the public inherits

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

1. The software development process is divided into several steps: defining issues, requirements analysis, planning architecture, software architecture (or higher-level design), detailed design, coding and commissioning, unit testing, integration testing, integration, system testing, assurance maintenance2. Build activities include: detailed design, coding, commissioning, integration, developer Self-test, u

: This article mainly introduces the first chapter: the overall architecture of the high-performance Web macro architecture. if you are interested in the PHP Tutorial, refer to it. The following blog posts will provide you with a relatively simple macro-architecture solution and detailed implementation and deployment tutorials. The preceding cluster environm

Some problems occurred recently when determining the project architecture model.ArticleAnd design. The following documents and designs are recorded for future Summarization: 1. enterprise application architecture model-patterns of enterprise application architecture Trial (enterprise application architecture patterns

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

If you say Taoxin potter, high availability is even more important than high performance. Why?Because you optimize the performance of the system 10 times times, your boss may say: "Xiao Dong Ah, good job."However, if you are responsible for the module, Zooey will be down, hey, you know.Availability Metrics99%-----website year unavailable for less than 88 hours99.9%---website year unavailable for less than 9 hours99.99%---website year is less than 53 minutesHigh-availability architectures most In

Python three-tier architecture description, python three-tier architecture A three-tier architecture usually divides the entire business application:Presentation layer, Business Logic Layer, and Data access layer ). The purpose of differentiation is to "High Cohesion and low coupling.High Cohesion and low coupling are the concepts in software engineering, the cri

Overall Architecture Analysis of muduo library and muduo Architecture Analysis Muduo is a high-quality Reactor network library, which adopts one loop per thread + thread loop architecture. The code is concise and the logic is clear. It is a good model for learning network programming. Muduo code is divided into two parts: base, net, and base to implement some bas

Simple web layer-3 architecture system (3rd edition), web layer-3 Architecture Today is the third edition. As we did a few days ago, we still need to optimize the code. The three-tier architecture is an idea. Whether the overall system security and high performance can be ensured depends on whether the code is properly written, whether the logic is rigorous. Ye

In the previous article I talked about the front and back of the separation of some views, this view is from a macro point of view, no concrete landing to achieve, today I will continue the topic of the previous article, from the front-end of the architecture design point of view of the front-end separation of a specific implementation of the program and I originally conceived a great change, But the core idea has not changed, is the control layer bel

Large-scale Internet architectureThe general idea of solving the problem is to divide and conquer (Divide-and-conquer), divide the big problem into several small problems, conquer. In the architecture practice of large-scale Internet, this kind of thought is not reflected.Architectural goals Low cost: The value of any company exists in order to gain business benefits. If possible, expect everything to be low cost. High performance: Site p
