tailieunhanh - Lecture Software engineering - Chapter 1: Software and software engineering

Chapter 1 - Software and software engineering. This chapter presents the following content: Software is designed and built by software engineers; software is used by virtually everyone in society; software engineers have a moral obligation to build reliable software that does no harm to other people; software engineers view "software" as being made up of the programs, documents, and data. | Chapter 1 Software & Software Engineering Slide Set to accompany Software Engineering: A Practitioner’s Approach, 7/e by Roger S.

What is Software? Software is: (1) instructions (computer programs) that when executed provide desired features, function, and performance; (2) data structures that enable the programs to adequately manipulate information and (3) documentation that describes the operation and use of the programs. What is Software? Software is developed or engineered, it is not manufactured in the classical sense.

What is Software? Software is developed or engineered, it is not manufactured in the classical sense. Software doesn't "wear out." Although the industry is moving toward component-based construction, most software continues to be custom-built. Wear vs. Deterioration Software Applications system software application software engineering/scientific software embedded software product-line software WebApps (Web applications) AI software Software—New Categories Open world computing—pervasive, distributed computing Ubiquitous computing—wireless networks Netsourcing—the Web as a computing engine Open source—”free” source code open to the computing community (a blessing, but also a potential curse!) Also (see Chapter 31) Data mining Grid computing Cognitive machines Software for nanotechnologies Legacy Software software must be adapted to meet the needs of new computing environments or technology. software must be enhanced to implement new business requirements. software must be extended to make it interoperable with other more modern systems or databases. software must be re-architected
