Software Systems Vs Software Engineering. Thats the applying of engineering to software. Software engineers tend to focus more on implementing software while systems engineers work with users and domains.
It is the application of engineering principles to software development. This is a current area of joint discussion between the two communities which will affect the future knowledge in both SEBoK and SWEBoK. Thats the applying of engineering to software.
Software Engineering is the study of how software systems are built including topics such as project management quality assurance and software testing.
Whereas the software system engineers can take a salary of 93280 a year. Software Engineering is basically a team activity. Thats the applying of engineering to software. One is that computer science deals with the science behind the interaction between hardware and software systems and computational applications whereas software engineering typically deals with the engineering principles of building designing and testing software products.
