Do not add complexity if it is not necessary.

The design pattern mentioned here is the pattern in software design, mainly refers to the object-oriented software design. Compliance with the design model can effectively improve the maintainability and reusability of
What kind of solutions are we going to talk about? How can we design a good design scheme? These problems are the issues that should be paid attention to during the preliminary design of software development.
When talking about software
Software Interface Design Principle original address: http://www.uml.org.cn/jmshj/200802015.asp
For application software, a basic reality is that the user interface is user-oriented. Users need applications developed by developers to meet their needs and are easy to use. The main principles of user interface design

Graphical user interface: The above functions can be integrated into a GUI interface based on Qt.
1) Think about the development of which module you are best at or interested in, and write on your blog.2) In addition to programming, you can contribute to a software project in a variety of forms, such as team management, requirements analysis, functional definition, algorithmic

Simulation of I2C bus multi-master communication research and Software Design
Author:■ Zheng Xuyang, Xi'an University of electronic science and technology, Li Bingbing, Huang Xinping
Abstract:This paper introduces the principle of multi-master communication simulating I2C bus, and proposes a new implementation method. This method uses delayed receiving comparison to implement arbitration, so that common Mic
In the software development process, the analysis is finished, is the software design.
The design phase of software engineering includes: design, code writing and software testing.

After the software is developed, there are only two groups to contact him. One is a user and the other is a developer. Therefore, when designing software, the two groups should consider simultaneously and weigh the key points of each design point from each angle.
The developed software is intended for users and use
You're still in the groove. How unreasonable is the prototype diagram given by the product manager?Do you still think how simple it would be if I designed this software?I often wonder,On the basis of satisfying the user's needs,How simple can our software be? recently want to do a personnel attendance system, located in small and medium-sized enterprises, the boss or personnel use, the size of the enterpris
Before I take this course, the code that I write in my mind and practice is still in a small project, and perhaps a simple project can solve most of the problems. But after this semester's study, I have a new understanding to the software development. When I think that some problems can be solved by programming, it is not only to look at the specific code implementation phase, but need to use a similar to the soft

Input boxWe can easily associate the prototype of the input box because it retains the shadow of the real world, both in shape and in operation:– Fill in the vacancy information vs. "Label + input box" combination in the form– Blanks can be filled in, the size of the white space depends on th
The development of software user interface has gone through the process from simple to complex, from low to advanced, the value of user interface in software system is more and more high. Thanks to the development and popularization of the Internet, the technical threshold of software development is declining, and most softwa
Overview DesignProfile design is an important phase of translating user goals and requirements into a specific interface design, where we need to get the design and data structure of the software (including mobile applications and websites) from the needs analysis of the previous phase.It is usually the complexity of t

This study is mainly in the design process of the inspiration method and design practice of some experience.For detailed programming work, it is normal to expect deterministic behavior because software design is nondeterministic.

To better elaborate the relationship between software humanized design and technical content, I personally think that we should start from the purpose of developing software. The software we refer to here should be commercial software for the majority of users, the developme
