used to simplify system-level software development, such as operating systems, user interfaces, and language processing. Typical examples include macapp and Microsoft's MFC.(2) middleware integration framework. It is used to assemble distributed applications and components. Typical examples include Microsoft's DCOM, Alibaba oft's RMI, And OMG's CORBA.(3) enterprise application framework. It is used in various application fields, such as telecommunications, manufacturing, and finance.It can be d

Research on layer-3 Architecture Concept of three-tier architecture User Interface presentation layer (USL) Business logic layer (BLL) Data access layer (DAL) Bll separates usl from dal and adds Business Rules Role of each layer 1: Data access layer: mainly refers to the operation layer for raw data (in the form of storing data such as databases or text files), rather than raw data, th

C/S architecture C/S architecture can also be seen as a fat client architecture. Because the client needs to implement the vast majority of business logic and interface display. In this architecture, the part of the client takes a lot of pressure because the display logic and transaction processing are included, to me

This post is used to record some of the good information about the design learning on the Internet that will continue to be updated. http://www.tech-q.cn/forum-28-1.html Web idea-Architecture design http://www.cnblogs.com/sunli/Internet system Architecture related Blog Http://hi.baidu.com/injava/blog Internet, search engine, system architecture, Java E

1. Architecture and framework design levels are different like hardware design, software design is divided into different levels. Typical software design levels are as follows: In this figure we can see that the framework is between micro-architectures and application level. DEISGN patterns is a micro-architectures-level design, and the framework is formed by multiple design pattern and other micro-architectural elements. The objectclasses, Micro-arch

1. Software Architecture Style A core issue of software architecture design is the ability to use repetitive architectural patterns, that is, the ability to achieve architecture-level software reuse. This means that the same architecture can be used in different software systems. For this purpose, scholars began t

The root of software complexity comes from the complexity of thinking. Three-tier architecture look at three-tier DDD Implementation detailed architecture look at Code Business Domain persistent layer (data layer) testing and use example complete code download Handy weapon Library: Fluent nhib.pdf Nunit Git (GitHub) For the tools involved in this article, see the previous article: My.

Large Web site technology Architecture (i)--large-scale website architecture evolutionEach pattern describes a problem that recurs around us and the core of the solution to the problem. This way, you can use the program again and again without having to do repetitive work.The so-called site architecture model is to solve the large-scale web site with high concurr

The previous article introduced the basic architecture diagram of Spring Cloud cloud service architecture, and we built the code based on the architecture diagram. Based on the concept of micro-service design, combined with spring Cloud's own service discovery, governance, configuration management, distributed and other excellent solutions, we use MAVEN technolog

The previous article introduces the integration of Spring Cloud service architecture-Enterprise distributed micro-service Cloud architecture diagram, which we build according to the architecture diagram. According to the micro-service design idea, combining some excellent projects of spring cloud, such as service discovery, governance, configuration management, r

The Jsse supports SSL and TLS protocols and provides functions related to data encryption, message integrity, and peer authentication.Client and server applications that use the following se

Three-tier architecture, three-tier architecture and mvc difference The three-layer architecture includes the presentation layer (UI) and business logic layer(BLL (Business Logic Layer ))Data Access Layer (DAL) and Object Library (Model) 1.

The data here is a combination of the information posted by nvidia and the data provided by NVIDIA in various seminars and school courses. There

Recently, I have begun to design a Service Release and governance framework. I have some experiences with the code of several mainstream frameworks, such as Alibaba Dubbo, netty at the transport layer, and tomcat at the container layer. The classic object-oriented analysis and design book explains why design is divided by hierarchy and the advantages of reading books and summarizing so many frameworks, there are some basic architecture design pattern

Computer Systems A Programmer ' s perspective Second EditionWe have seen a processor must execute a sequence of instructions,where each instruction performs some primitive operation, such as addingThe numbers. An instruction are encoded in binary form as a sequence of 1 or more bytes.The instructions supported by a particular processor and their byte-level encodingsis known as its Instruction-set architecture (ISA). Different"Families" of processors,

Document directory Game Logic Sound Graphics Output The second article is too simple. I will not translate it when I get started with Android development. The third article is about the basic game architecture. Our Android program can run. You may want to know what kind of program is a game. Let's talk about my understanding. The following table shows the architecture of a game. Game

To. NETArchitecture Design-Chapter 4-Business Layer layered architecture (Part 1) In the previous article, we discussed two business logic models: Transaction Script and Active Record. This article describes the Domain Model and Anemic Model. Note: No matter how difficult the technology is, we still have to implement the technology in a down-to-earth manner. I also hope that my friends will continue to support this series. This topic is as follows:
