In the previous article, we discussed what a schema is. In fact, these basic concepts are very important for architecture, and most people think they are aware of the concepts they are accustomed to every day, but in fact they are subconscious and not active. For example, "What is a table?" "When I do training, I often take this example to ask you, answer all sorts of strange things." This actually led to the structure of the time, the different roles

This article is the nineth of a rambling architecture column, in which Kevin takes fire as a starting point and introduces the relationship between technology, business and architecture in depth. As the authors have said, technology has always been created in the context of human settlement of the demands of the business, and the aim is to gain greater and better benefits.One day to eat with friends just to

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

Analysis of. NET logic layered architecture, analysis of. net Architecture I. Basic Knowledge preparation: 　　1. layer principles: (1) Each layer is called by the upper layer in interface mode.(2) The upper layer can only call the lower layer.(3) Dependency can be divided into loose interaction and strict interaction. 　　2. Business Logic classification: (1) application logic.(2) domain logic. 　　3. layer used

in the Agile development , we did find a framework that would enable domain experts, architects, to work together to design an adaptable ROA architecture. But I think we should think of it from another angle. ...even domain experts and architects can work together in a team, but after all, domain experts and architects are people, not gods. So, in the end, how much of the future needs change can be predicted from the current version ? This is really

by Vikas Singh on SepIn 3-layer architecture 3-layer architecture separates the application into 3 components which consists of Presentation layer business layer and D ATA Access Layer. In 3-layer architecture, user interacts with the Presentation layer. 3-layer is a linear architecture. In MVC

Write in front　　From the beginning to write code to now, has done several projects, BS and CS have, has always been a code of farming. However, as a progressive programmer, there is an ideal to become an architect. So, in peacetime work, but also actively to see a variety of books, see the Garden inside the fine article. Hope, in this pursuit of the dream of the road, can leave little bit, also is a kind of consolidation of knowledge, some share.Reading experience Soon after work, I read the fi

The previous article introduces the basic architecture diagram of Spring Cloud cloud service architecture, this article constructs the code according to the architecture diagram, according to the micro-service design idea, unifies the spring cloud own service discovery, the governance, the disposition management, the distributed and so on the project outstanding

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

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

Introduction:What does methodology mean for software development? How do we look at the methodology in software development? Can methodology become a lifeline for software development? After reading this article, these questions will be answered. In Article 1ArticleTo understand the meaning of some words in the title. What is methodology? What is agility? Why is architecture discussed? Methodology The methodology is methodology
