What is the best book to learn software engineering ?

Question

(DFD-UML)

Answer 1

If you're looking to learn the principles behind everything as well I can't recommend a book more than:

Software Engineering by Ian Sommerville.

I think it's on the 9th edition now, I have the 8th and it's still relevant so if you shop around you should be able to get a bargain.

I used it as a 2nd year Computer Science student at University, and have used it since, and still use it teaching undergraduates!
