to be integrated together to solve software engineering problems. This is also the responsibility of the software architect. A software architect can be understood as an engineer who does not have to fully master all sub-fields of software engineering. They are dedicated to Architecture Design and understand the differences between various engineering technologi

used in engineering application to software. The three elements of software engineering are methods, tools and processes. The main challenge of software development is the problem of legacy systems, the requirements of high-reliability software development and the change of software development mode. The professional ethics construction of software

From the perspective of engineering practice, this article describes software system development-general Linux technology-Linux programming and kernel information. The following is a detailed description. I am very happy to have this opportunity to communicate with you about software development. I should be a typical computer science class. From my bachelor's degree or master's degree to my PhD degree in t

There are many commonalities in information systems. If it is developed as a product, how can it be reused and expanded through the platform? The product line engineering method in the industry is a method for large-scale reuse. I also lived in the garden for a short time and found that the majority of technologies are concerned. In addition to technologies, there are still many issues that need to be conce

stores that can make full use of fabric and color to predict future fashions will have a competitive advantage. But with 7 times 24 hours of network connectivity and global information sharing, you've just come up with a good idea, and your competitors will be imitating it. This makes us go back to the idea that companies that can take advantage of software-building processes will have a huge competitive advantage over their competitors. The key word for this concept is "process". It is irrele

The 1th chapter summarizes the historical development and basic principles of software engineering, discusses the latest software engineering knowledge system and the code of Professional Ethics of IEEE and ACM. In the first section we divided the software into general-purpose software and custom software, and then we learned about the features of the software th

Chapter I. mainly divided into1, Software2, Software engineering3, Software engineering knowledge system4, four parts of the Code of Professional ethics of software engineering. Software is the masterpiece of human thought creation,and become a catalyst for modern human life.;The first part of the software on the characteristics of software, development and software crisis is explained, mainly describes

design pattern describes the solution of common problems in the system design process, which is summed up from a large number of successful practices.User interface design is critical to the success of a system, is a design multidisciplinary activity, and a good user interface design requires graphic artists, demand analysts, system designers, program developers, technical experts, social and behavioral scientists, and even some professionals associated with system characteristics to work toget

in the mola* and armor* systems is based on quorum, which means that the data is successfully updated on most replicas.14. The Waro mechanism is also used for replica management in Big pipe*.Iv. Log Technology1. Log technology is one of the main technologies for downtime recovery. The log technology was originally used in the database system. Strictly speaking, the log technology is not a distributed system technology, but in the

The object-oriented design phase includes architecture design, detailed design, user interface design and database design. Design activities are divided into system design and detailed design. Design principles are modular (large system decomposition into a number of small systems), coupling degree (the degree of association between two subsystems, the lower the coupling the better), cohesion (the degree of

2,34. As the title says, the program is a personal behavior, in the case of ACM, such as the topic, according to the topic to write a number of lines of code, the use of an algorithm to complete the topic requirements, just input and output is enough, this can be said to be a simple program, is to complete a program. And a software is a large project, the software has a number of components, the need for a number of different people to work together, the design of the case-form interface, the es

Software evolutionThis chapter introduces the concepts and methods of software evolution, including the characteristics of software evolution, software maintenance activities, reverse engineering and re-engineering.Software maintenance is an inevitable process. Software maintenance is the modification of software products during the operation or maintenance phase of the software, which may be to correct errors in the software or to add new functionali

Software Engineering--Evolution of theory, method and practiceOnce the software is in use, some of the exposed software problems need to be further revised and improved, while new requirements will continue to emerge, and the original requirements will change as the business changes. Therefore, the software system continues to evolve after delivery, that is, to go into the software maintenance phase, in order to ensure the long-term availability of so

Demand EngineeringThis chapter takes the object-oriented technology as the core, comprehensively, deeply and systematically introduces the tasks, processes, methods and tools of each stage of software development.Software requirements can be divided into business requirements, user requirements, system requirements, functional requirements and non-functional requirements and other types. Requirements engineering is the application of proven
