system has a lot of usability problems, if users develop habits, they will not notice them, even if you give him a better choice will be rejected. As Zhao said: Just because people get used to it. Back to Windows, regardless of its design right or wrong, if the user is accustomed to, you will think that the software should be so designed, and this does not conform to the

The difference between software engineering and computer science:Computer science and software engineering are all in the same category, and the connection between them is very close.Computer science, focusing on the basis of computers, a lot of what is more than learning but not very deep, some schools four years without direction, and some schools will be divid

After many "frameworks" are designed, You need to carry the burden of the entire framework. This is not good. The software should be able to remove unnecessary functions from the user's choice. A good software design should be able to increase or decrease. In this sense, the. net dll encapsulation mode is not as good as the Java class + jar zip package mode. A

Computers, as one of our daily equipment, once such a fault occurs, it can be imagined that the troubles we encounter, especially some cainiao friends, will be helpless in the event of a fault, the ongoing work on hand cannot be completed on time. I am confused and afraid to break the hardware and equipment, and the maintenance must bear economic losses. In fact, we don't have to worry so much. When a computer encounters a problem, it often suffers fr

It is small and exquisite design, no need to upgrade, easy to install, easy to operate, no mainframe, a press is used. With officestation™ solutions, you can enable multiple u

The design mode is just a hammer! When talking about the design model, it was almost unknown and unknown. The famous "gof" (some Chinese translated as "the four-person gang") was an amazing work. It was really "no one knows about gof in my life, and I have never learned how to design it!" However, the design model is r

Software Engineering is the development of software as a concrete project to study, mainly in the project progress, engineering quality, engineering costs and other aspects of control and grasp, pay attention to the macroscopic aspects of things. Computer science and technology, in favor of specific technical realization, technology development, and so on, in fav

Computer Science focuses on the study of hardware and computer theory, studies the science of computer and its surrounding phenomena and laws, studies the structure of computer systems, program systems (i.e. software), artificial intelligence, and the nature and problems of

OverviewDesign patterns are a set of reusable, most known, categorized purposes, code design experience Summary. Design patterns are used in order to reuse code, make code easier for others to understand, and ensure code reliability. There is no doubt that design patterns in others in the system are multi-win; Design p

What is antivirus software? Antivirus software is a virus, Trojan horse and so on all known to the computer has a harmful program code to clear the program tool. "Antivirus software" by the domestic generation of anti-virus software manufacturers name, and later because of

As we all know, design principles are the cornerstone of design patterns. When the design principles are followed, the written code becomes very flexible and can cope with changes and be easier to maintain. Of course, it is not so absolute. Next, we will briefly introduce some basic design principles, and then introduc

Every day, countless people are plagued by computer viruses. Every day, people boast about how effective the anti-virus software he uses is. Today, hundreds of computers are killed. Anti-virus software vendors do not forget to remind them to buy their genuine anti-virus software every day. Do not forget to upgrade thei

"Any problem in the computer science field can be solved by adding an indirect middle layer" This sentence almost summarizes the key points of the design of the computer system software architecture. The entire architecture is designed in strict hierarchy from top to bottom. The entire system of

30-minute understanding of Object-Oriented Design Principles Many people have read the design patterns, but Martin does not have much estimation on the object-oriented design principles (For details, refer to Agile Software Development: Principles, models and practices). In fact, the two are complementary: the
