Software engineering is mainly about learning programming, which has higher requirements for foreign languages and mathematics and lower requirements for physics. A foreign language should be proficient in reading foreign materials, and the mathematical relations behind various things should be abstracted mathematically.

Software engineering is a discipline that studies the construction and maintenance of effective, practical and high-quality software by engineering method. It involves programming languages, databases, software development tools, system platforms, standards, design patterns and so on.

In modern society, software is used in many aspects. Typical software includes e-mail, embedded system, man-machine interface, office suite, operating system, compiler, database, games and so on. At the same time, almost all industries have computer software applications, such as industry, agriculture, banking, aviation, government departments and so on. These applications promote economic and social development, and also improve work efficiency and life efficiency.
