-14, with little meaning.7. Do not pay attention to the details:The preliminary design should not pay attention to details. For example1. Only the object name is identified for each object, and its properties and methods are not recognized.2. "Current Account Pin user interface", which may be a dialog box, Web interface, character terminal interface, but the robust diagram does not care about these details.3. Are entity objects such as "customer data"

The computer software industry is a young industry born in 1950. It has only a history of more than 50 years. In contrast, architectural design can be traced back to the Egyptian pyramid era thousands of years ago, or even earlier. Therefore, computer software designers can learn a lot from architects. There are obvious similarities between the

Memory is an important module in the Integrated Design of SOC (system on chip, on-chip system) and a significant proportion of cost in SOC. The software and hardware design of memory management is an important part of SOC Software Architecture

the subsequent article in-depth analysis, extraction design structure and design skills of the essence, for the vast number of software industry colleagues to share. 2. Basic knowledge of SCA specification The SCA programming model is highly extensible and language neutral, and it is easy to be extended to various implementations of language technology java,c+

servers are used, when one server goes down, only part of the data in the system is unavailable, not all. Therefore, database splitting can not only use multiple servers to share the load pressure on the database, but also improve the overall availability of the system. There are two ways to split data::Vertical Split and horizontal split.1.1 Vertical Split Vertical splitting refers to splitting the data tables accessed by each module into different databases according to the system function mo

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

to more reasons for its changes. This will lead to dependency between duties and affect each other, greatly damaging their cohesion and coupling. A single responsibility usually means a single function. Therefore, do not implement too many function points for the class to ensure that the entity has only one reason for its change. Therefore, the core of the SRP principle is to require only one change to the class. classes that violate this principle should be reconstructed, for example, separa

1) physical architectureThe purpose of the physical architecture is to determine the topological structure of physical nodes and physical nodes. The physical nodes include servers, PCs, dedicated servers, software installation, deployment, and writing, and system software selection; the Topological Structure defines the relationship between physical nodes. 2) Op

The Open Web SSO project provides core identity services as the infrastructure of security components to achieve transparent single-point login. The main goal of this project is the web layer, which provides the foundation for seamless integration of different web-based applications. These applications can enable different identity libraries and platforms, for example, based on web or application server. This project provides Sun Java (tm) System Access Manager Code.

Practice of one-time invoicing Software Architecture (I) -- Overview 1. Structure Based on experience, we can find that an interface is always one piece. Each piece contains some basic controls (such as buttons, text boxes, and date controls), as well as a grid control and tree control, if each block is called a region, it becomes an item. In this way, we can abstract the interface into two base classes

The Open Web SSO project provides the core identity service as the infrastructure of the security components for transparent single sign-on. Its primary goal is the Web layer, which provides the foundation for seamless integration of different web-based applications that enable different platforms, such as web-based or application servers, to be based on different identity libraries.
