1. Warehouse Style In the repository style. There are two different components: the central data structure shows the current state. The independent component is executed on the central data storage. The interaction between the warehouse and the external component is greatly changed in the system. If a process execution is triggered at a certain time in the input stream, the repository is a traditional database. On the other hand, if the current state of the Central Data Structure triggers the pr

Hello everyone:As a software developer, I'm sure everyone has thought about the question: Why is the performance of the native Godson processor so different from Intel's processor performance in the same period? Why is domestic open source software development far less than abroad? ------is our software developer's own lack of literacy? Or is it the hardware perf

Concurrency Mode Two models designed to share resources among multiple threads or processes: · The Active Object design mode separates method execution from method calls. The purpose is to enhance concurrency and simplify synchronous access to objects residing in the control thread. · The monitor Object Design Pattern synchronizes the execution of Concurrent methods to ensure that there is only one method running within the object at the same time. It also allows the execution sequence of

First introduce the side-slip menu, and the main content page.The slide-by menu is registered in the first oncreate of the software. and set parameters, such as slide-slip mode and the number of pixels sliding.2. Write the layout file for the

The three mainstream Web services implementations currently known are:REST: Representational state transitions (software architecture style)SOAP: Simple Object Access ProtocolXML-RPC: Remote Procedure Call protocolBrief Introduction: REST: Characterize state transitions (representational states Transfer), using a standard HTTP method (Get/put/post/delete) for Web services to abstract the services of all WEB

Layer 3: Business, IT implementation, and Interaction The future software should be a service provider in the traditional industry, and the future software should be highly interactive. Therefore, based on these two aspirations, we have come up with a three-layer architecture of future software. Or three major pieces

Abstract: Software philosophy, software path, silver bullet, Wolf, software architecture, see: top ten proposition programming rules for eliminating wolf in sequence Sage said: Gu Shen does not die is called Xuan. The door to xuanjicang is the root of Heaven and Earth. It is useless if it is stored. The key to ap

release it explicitly when exiting the critical section. 2) inflexible and inefficient. Depending on the context in which the application is running, different lock types are required for implementing the critical section. However, if the lock primitive is hard-coded to the software in every place in use, it is completely unnecessary and time-consuming to change the primitive. These modes can alleviate the above problems to simplify serialization

service and adapts to the presentation layer. Here we will talk about macro services and microservices. Macro services have some coarse-grained services. A user's usecase operation, such as an e-commerce order, CreateOrder is a macro service, rather than fine-grained goods inventory check and order legality. The corresponding microservice is sometimes called an Application Service). It is represented by the logic details of the problem domain, such as the fine-grained services such as inventory

more than ten years. However, while the industry is evolving, some of the things that asterisk, such as the basic concept of channels, flexible call handling using dial plans, still support the development of complex telephony systems. there is one area where the asterisk architecture has not been handled too well, that is, how to make the system scalable across multiple servers. The asterisk development community is developing a partner project call

Hierarchy in Software System Architecture About the layered structureAs we all know, the classic three-tier structure includes the data access layer, business logic layer, and presentation layer. Of course, if you continue to expand, it can also be divided into four layers, five layers ...... I believe that many people have used it and many people have written it. But why is it so difficult for some people

There are no software development companies that do not use a three-tier architecture or higher-level architecture. For example, if your project team has three people. If a layer-3 structure is used, the job can be split into one person as the UI Layer, one person as the data access layer, and one person as the business logic layer. Everyone is responsible for

MVC to your application, and because of the strict separation of the model and the view, it is also difficult to debug the application. Each component needs to be thoroughly tested before it can be used. Once your components have been tested, you can reuse them without scruple.Based on my personal experience, since we have divided an application into three parts, using MVC also means that you will be managing more files than before, which is obvious. It seems that our workload has increased, bu

http://blog.csdn.net/horkychen/article/details/46612899From the point of view of architecture design (so-called composition theory), software systems are modules and interfaces.The module (Hierarchy/component) determines the division of labor, and the interface determines interaction.An API is the definition of an interface. The modules do not need to be concerned with the implementation of other modules, o

according to the configuration file (Struts-config.xml) Delegate the request received by Actionservlet to the appropriate action handler. In the business layer, the spring IOC container that manages the serviced component is responsible for delivering the business model component to the action and the component's collaboration Object data Processing (DAO) component to complete the business logic and to provide container components such as transaction processing, buffer pooling to improve system
