What is software enginering

-
Software engineering (SE) is the application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software, and the study of these approaches; that is, the application of engineering to software.[Alain Abran, James W. Moore ; editors, Pierre Bourque, Robert Dupuis. (2004). Pierre Bourque and Robert Dupuis. ed] It is the application of engineering to software because it integrates significant mathematics, computer science and practices whose origins are in engineering.[ACM (2006). "Computing Degrees & Careers". ACM. Retrieved 2012-03-05] It is also defined as a systematic approach to the analysis, design, assessment, implementation, testing, maintenance and reengineering of software, that is, the application of engineering to software.[Laplante, Phillip (2007)] The term software engineering first appeared in the 1968 NATO Software Engineering Conference, and was meant to provoke thought regarding the perceived "software crisis" at the time.[Peter, Naur; Brian Randell (7–11 October 1968)][Randell, Brian (10 August 2001)].
Software development, a much used and more generic term, does not necessarily subsume the engineering paradigm. Although it is questionable what impact it has had on actual software development over the last more than 40 years, the field's future looks bright according to Money Magazine and Salary.com, which rated "software engineer" as the best job in the United States in 2006.
