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

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

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

The following content is both my understanding and the translation of the content, the title of the translation is:N -tier architecture, including two aspects of the architecture. On the one hand, N-tier 's physical architecture, on the one hand, is the logical architecture of n-tier . In general terms, the physical

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.

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
According to Linda Rising's book pattern almanac, there are more than 70 known architecture models. This is only a lot of statistics, including a lot of patterns that are generally considered to be design patterns, such as bridge, facade, interpreter, mediator and other models are generally considered as design patterns, however, in many cases, it can also be used as an architecture model, so it is often us

Most engineers, including architects, started from the micro-architecture. Micro-architecture refers to the rationality of design and implementation in a local field, for example, the rationality of writing a sort program to achieve the complexity of time space, at the same time, it has reached a reasonable standard in terms of code readability, scalability and maintainability.

ExampleTo demonstrate how the layered architecture works, imagine a scenario, such as Table 1-4, in which the user sends out a request to get the customer's information. The black Arrow is the request stream that obtains the user data from the database, and the red arrow shows the direction of the return of the user's data. In this example, the user information is made up of customer data and an array of orders (orders placed by the customer).The user
