Basic Principles of Software Engineering)

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

The method and practice of software engineering theory

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

Discussion on Software System Development from Engineering Practice

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

Software product line engineering methods-four main methods and principles

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

On five ways of benefiting from agile engineering practice

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

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

Reading "Software Engineering-theory method and Practice" eighth chapter experience

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
