Engenharia de Software 3. Enviado por Gustavo flag Denunciar. Software, in the guise of the now-infamous Y2K bug, would fail and, as a result, stop the world as we then knew it. Computer software has become a driving force.
Software Eng, Roger Presmen
It is the engine that drives business decision making. It serves as the basis for modern scientific investigation and engi- neering problem solving. It is a key factor that differentiates modern products and services. It is embedded in systems of all kinds: Software is virtually inescapable in a modern world.
And as we move into the twenty-first century, it will become the driver for new advances in everything from elementary education to genetic engineering. Computer software is the product that software engi- neers design and build. It encom- passes programs that execute within a computer of any size and architecture, documents that encompass hard-copy and virtual forms, and data that combine numbers and text but also includes representations of pictorial, video, and audio information.
Software engineers build it, and virtu- ally everyone in the industrialized world uses it either directly or indirectly. Why is it important? Because it affects nearly every aspect of our lives and has become pervasive in our commerce, our culture, and our everyday activities. What are the steps?
You build computer software like you build any successful product, by apply- ing a process that leads to a high-quality result that meets the needs of the people who will use the product. You apply a software engineering approach. What is the work product? From the point of view of a software engineer, the work product is the pro- grams, documents, and data that are computer software.
Read the remainder of this book, select those ideas appli- cable to the software that you build, and apply them to your work. New software-driven industries have arisen and old ones that have not adapted to the new driving force are now threatened with extinction. As its importance grows, the software community continually attempts to develop tech- nologies that will make it easier, faster, and less expensive to build high-quality com- puter programs.
Some of these technologies are targeted at a specific application domain e. However, we have yet to develop a software technol- ogy that does it all, and the likelihood of one arising in the future is small. And yet, people bet their jobs, their comfort, their safety, their entertainment, their decisions, and their very lives on computer software. It better be right.
This book presents a framework that can be used by those who build computer software—people who must get it right. The engenharla encompasses a process, a set of methods, and an array of tools that we call software engineering.
It is a product and, at the same time, the vehi- cle for delivering a product. As a product, it delivers the computing potential embod- ied by computer hardware or, more broadly, a network of computers that are accessible by local hardware.

Whether it resides within a cellular phone or operates inside a mainframe computer, software is an information transformer—producing, manag- ing, acquiring, modifying, displaying, or transmitting information that can be as sim- ple as a single bit or as complex as a multimedia presentation. As the vehicle used to deliver the product, software acts as the basis for the control of the computer oper- ating systemsthe communication of information networksand eedio creation and control of other programs software tools and environments.
Software delivers the most important product of our time—information.
Software transforms personal data e. The role of computer software has undergone significant change over a time span of little more than 50 years. Sophistication and com- plexity can produce dazzling results when a system succeeds, but they can also pose huge problems for those who must build complex systems. Popular books published during the s and s provide useful historical insight into the changing perception of computers and software and their impact on our culture.
Osborne [OSB79] characterized a “new industrial revolution. As the s began, Toffler [TOF90] described a “power shift” in which old power structures governmental, educational, industrial, economic, and military disinte- grate as computers and software lead to a “democratization of knowledge.
