[Architecture design] DDD Experience Sharing (Part 1)
System Analysis stage (SA)
In the system analysis phase, the main task is to propose a solution to the customer's needs and analyze the system architecture. Generally, UML configuration diagrams, Suite diagrams, and other tools are used to complete system analysis. Finally, we will organize the
logic layer, encapsulate the complex processing at the underlying layer, and provide users with simple interfaces. Such examples can be seen everywhere. The facade mode is often a system architecture design. In my projects, the interface of the facade mode is implemented, providing the best solution for the decoupling of complex systems.

Introduction:We have discussed four process models for agile architecture design. In this chapter, we will summarize these four process models, the relationships between the four persons and the Agile Methodology characteristics embodied in the model are discussed. Through the description in this chapter, you can have a better understanding of the previous content.

Before we took two articles, we explained in detail the nginx principle, installation and feature components. See Load Balancing Layer Design (2)--nginx installation (http://blog.csdn.net/yinwenjie/article/details/46620711) and architecture design: Load Balancing layer Design (3)-- Nginx Advanced "(http://blog.csdn.net

As shown above, the framework mainly includes:
• MVC Development Framework
L Workflow Technology
L Users, permissions, role management
The details are detailed below. 2 MVC Scenario 2.1 View Layer Technology Scheme (view)
In the application of common development framework, it is used in the view layer: JSP, JSF,FREEMARKER,XSLT
compression, or other.
The final robust diagram is shown in Figure 8-13. The compression function also supports displaying the compression progress and canceling the compression at any time. Therefore, you have recognized the responsibilities of compressing the traveling interface and listener.
5. Only draw robust diagrams for key functions (Use Cases)
Based on the concept that "key requirements determine the architecture", functional requirements
-container, and the Request and the Response object in it are like the water flowing in the pipe, and Valve is a small opening on the tube that gives you the opportunity to get in touch with the water inside and do something extra.In order to prevent water from being drawn and not flowing into the next container, there is always a node at the end of each tube to ensure that it will flow to the next sub-container, so each container has a standardxxxvalve. As long as the link is involved in the pr
Design patterns are one of the best ways to share design ideas. Design patterns provide software architects and designers with the tools or languages they need to solve recurring problems in a systematic way to gain some experience. This series includes two sections that discuss ways to use design patterns to solve you

It is not easy to develop software that is satisfactory to users. Software architects must fully grasp the possible conflicts between various requirements and weigh requirements, different requirements are met in different categories. This article starts from understanding the complexity of the requirement types and demonstrates how to design the architecture based on different requirements through

Before explaining the system architecture design, it is necessary to supplement the concepts related to the architecture. Therefore, this blog post mainly describes the concept

How to better software architecture design, this is a software engineering field of an eternal key topic. Over the past few decades, the International Software engineering community has made great strides in software architecture design, and a large number of books, articles and literatures record the mature experience
1. OverviewThe first two times in this article, we have been talking about the construction of Nginx + keepalived. At the beginning of this article, we are going to honor the promise of the previous article, the following two articles we will introduce the Nginx + keepalived and LVS + keepalived to build a highly available load layer system. If you do not know about Nginx and LVS, see my previous two articles, "Architecture

Mobile gaming platform Server design at present there are mainly based on the socket state connection and HTTP stateless connection two kinds of architectures. Because the mobile phone users of the network traffic sensitivity and changes in the network state than the PC environment to be complex, so for card games basic use of HTTP connection architecture.
