An excellent architect always has a good balance between the merits of various solutions and the corresponding cost, which is the architect's rich experience and broad knowledge system. The message-based software construction model is the architect's necessary knowledge point, this article will describe the model's evolution process in detail. Remember the first time I was dealing with the company's software

Purpose:
The Software Overview Design Manual is an important document in the development of "vyy". The work done is to convert the data flow diagram in the requirement manual into the software structure and da
interpretation of the material is not transparent, so let us beginners are vague concepts, understanding wrong, very regrettable. ”"Ah, I always thought that MVC is a three-tier architecture, it seems really wrong." So what exactly is the three-storey? ”"I have not told you already." You see, whether it's an application WinForm, or a Web page program aspx, they're mostly for doing. ”"For the interface to display and process, yes, they can be seen as
and Web service technologies are typical point-to-point structures.
Interactive Software
Model-View-controller (Model-view-controller)
When the user interface of the application is very complex, and the requirements of the user interface are easily changed, we can abstract the interaction type software into three kinds of component units, the model, the view and the controller, whic
" technologies, we must first clarify three issues.
First, what is the C/S structure.
The C/S (Client/Server) structure is a well-known client and server structure. It is a software system architecture. It can take full advantage of the advantages of both ends of the hardware environment, and assign tasks to the client and server, thus reducing the communication overhead of the system. Currently, most appli
: Data and operations. In C language, struct is only a collection of data. We can use a function pointer to simulate struct as a "class" that contains data and operations ". The following C program simulates the simplest "class ":
# Ifndef c_class# Define c_class struct# EndifC_class{C_class A * a_this;/* This pointer */Void (* Foo) (c_class A * a_this);/* behavior: function pointer */Int A;/* Data */Int B;};
We can use the C language to simulate three features of the forward Obje
-called power management properties, you can configure the system in different power modes (such as AC power, battery, etc., because the spiral machine is a PC, so there is no battery-powered option), in the inactive state, how long after The system shuts down display, or enters the sleep state.This article will focus on the various nouns mentioned above, describing their meanings and how they are implemented in the kernel. Before you begin, explain the meaning of these words.
Shutdown,
c/s--client/ server, simply speaking, the client computer needs to install proprietary software to communicate more servers, just like QQ. Mainly through the mechanism of the message to pass (of course, can also write their own protocol, the game is done.) )
b/s--Browser/service side , you can communicate with the server as long as you have a browser, no need to install a dedicated client, communication protocol using the HTTP protocol ... Like WEBQQ.
Software architecture is more important than writing code. The architecture design of the software system requires how the components of the design system are divided, how the components interact, and the logical, physical, and sy
data structure error (variable initialization, address overflow, etc.), boundary condition error, module interface error, code independent path error, improper handling of exception, etc., which involves the detailed unit test and integration test;5. The errors caused by the software design architecture, such as the caching mechanism, need to be considered in te
operations on specific data. The class contains two categories: Data and operations. In C language, struct is only a collection of data. We can use a function pointer to simulate struct as a "class" that contains data and operations ". The following C program simulates the simplest "class ":

Writing C # for Visio two development of a series of articles, are written some experience and technical knowledge of the sharing, this article continues to explore the development of some of the experience, mainly introduces the next WinForm interface design and Visio software architecture design. Let's take a look at
the parent class, the post-condition (that is, the return value of the method) of the method is stricter than that of the parent class;
Dependency inversion principle:
Invert dependency to dependency Interface
Upper-layer modules should not depend on lower-layer modules. They all depend on an abstraction;
Parent classes cannot depend on child classes. They all depend on abstract classes;
Abstraction cannot depend on or depend on abstraction;
Interface isolation principle:
The dependence of a
Abstract:
The database is the foundation of the system. If you need to change the fields of the database frequently, or even modify the table and table relationship, I believe that no one will be able to cope with it several times! Because of the changes in the database structure, not only the changes in the database itself, but also the code at the entity, data operation, logic, and performance layers must be modified. What's more troublesome is that if a large amount of old data already exist
Architecture Design for rest
REST (representational state Transfer) is a lightweight Web service architecture style that is significantly simpler to implement and manipulate than soap and XML-RPC, and can be implemented entirely through the HTTP protocol, Cache caching can also be used to improve responsiveness, performance, efficiency, and ease of use over the S

In the previous article, we initially learned about the OO design. The most unique feature of the OO design is the way he views the needs. In this way, we do not need to rush to determine which processes the software needs to implement, which functional points should be designed, and which pictures should be made. Instead, we need to focus on some more basic conc
