I am a computer science and technology major, and now I am a sophomore. I want to minor in subjects related to my major. What should I learn?

Computer-related, nothing more than: network technology, you are a girl, it seems not suitable unless you learn the management of operating system; Software development, I can't help it if I don't like it. Otherwise, I would still recommend this direction, because now all major cities are developing into big software cities, such as Nanjing, which is building a famous software city. There should be many employment opportunities and development space. Large database, this direction can only be recommended to you, whether it is Oracle, DB2 or SQL Server, you can learn and study. As a database administrator, you shouldn't have manual labor like web workers, and it's not software development. You don't like it. One more thing, the older the DBA, the more popular he is. Unlike programmers, you have to be a project manager when you are old. The last direction, CG direction, needs the content of your personal artistic cells.
