A software engineer applies principles of software engineering to design, develop, maintain, test and evaluate software and systems. They work for businesses, government agencies and non-profits. Most software engineers work 37-40 hours per week in an office setting, but may sometimes work remotely or odd hours depending on clients. Software engineering can be divided into ten subdisciplines and involves developing information systems through stages of the system development life cycle. An information system collects, organizes, stores and communicates information, and can refer to either computer systems or just software. Information systems in organizations are influenced by the organization's IT department.

3. A software engineer is
a person who applies
the principles of
software engineering
to the design,
development,
maintenance, testing,
and evaluation of the
software and systems
that make computers
or anything containing
software work.

4. Most software
engineers work as
employees or
contractors. Software
engineers work with
businesses,
government agencies
(civilian or military),
and non-profit
organization.
Employment

5. Work
Most Software Engineers
work 37 to 40 hours per
week. This job is office-
based, and most of the
work is done during
normal office hours, but
can sometimes lead to
working away and
working late or during
weekends, depending on
where and when the
client is situated. The job
can also be done at home
or anywhere a computer
is set up.

7. Software engineering
can be divided into ten
sub disciplines

19.  An information system is any
organized system for the collection,
organization, storage and
communication of information. A
computer Information System (IS)
is a system composed of people
and computers that processes or
interprets information.The term is
also sometimes used in more
restricted senses to refer to only
the software used to run a
computerized database or to refer
to only a computer system.

20.  Types of information system
The "classic" view of Information
systems found in the textbooks
in the 1980s was of a pyramid of
systems that reflected the
hierarchy of the organization,
usually transaction processing
systems at the bottom of the
pyramid, followed by management
information systems, decision
support systems, and ending with
executive information systems at
the top. Although the pyramid
model remains useful.

22.  Information technology
departments in larger
organizations tend to strongly
influence the development, use,
and application of information
technology in the organizations.
A series of methodologies and
processes can be used to
develop and use an information
system. Many developers now use
an engineering approach such as
the system development life cycle
(SDLC), which is a systematic
procedure of developing an
information system through stages
that occur in sequence.
