Software engineering (SE) is the profession that creates 
and maintains software applications by applying 
technologies and practices from computer science, project 
management, engineering, application domains and other 
fields.

Software engineering, like traditional engineering 
disciplines, deals with issues of cost and reliability. 
Some software applications contain millions of lines of 
code that are expected to perform properly in the face of 
changing conditions, making them comparable in complexity 
to the most complex modern machines.

Software Engineering is a profession which deals from 
designing , coding and testing and maintenance of the 
software.  In other words it creates and maintenance 
software applications...

Monitering and measuring the strength of the development 
process

systematic rules and procedures that we follow in 
developing the software application.

Software engineering 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.
The term software engineering first appeared in the 1968 
NATO Software Engineering Conference and was meant to 
provoke thought regarding the current "software crisis" at 
the time. Since then, it has continued as a profession and 
field of study dedicated to creating software that is of 
higher quality, more affordable, maintainable, and quicker 
to build. Since the field is still relatively young 
compared to its sister fields of engineering, there is 
still much debate around what software engineering actually 
is, and if it conforms to the classical definition of 
engineering. It has grown organically out of the 
limitations of viewing software as just 
programming. "Software development" is a much used term in 
industry which is more generic and 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 who rated "software engineering" as the best job 
in America in 2006.
