Editor's Notes
- Hello students. Have you ever tried to build up a software. No..hmm. You are now at the right place. From today onwards we will teach you software engineering. The art of developing softwares.
- Language?? Hmm… It doesn't matter right now. Because from this course, we're focusing on learning theoretical basics and standard practices in software lifecycle. So Java, Python, PHP... we actually don't care. What we're learning here is applied to all of those languages.
- And remember, it is not only the developer who builds the software. In a software project, you will meet business analysts, testers, project managers, technical writers....and many more people. So we will learn what all of them do, to come up with a nice looking and effective software. After successful completion of this course, you will get to know software engineering principles and techniques that are used in developing quality software products.
- Before learn to develop a software, we need to know what is a software. What kind of softwares can we build. We generally define software as a set of instructions given to a computing device, that make the device work. When I say computing device, it can be your desktop computer, laptop computer, your mobile phone, a scanner, printer and even your washing machine. So it means any device which can do a computational process.
- Software you built can be held either on your computer’s hard disk or on a CD/DVD or on your pen drive. I mean any storage device you can use to store it. But to process the instructions it need to be loaded into the computer’s RAM (Random Access Memory) prior to the execution of each instruction.
- OS - OS X (formerly "Mac OS X"), Linux, Microsoft Windows An operating environment is usually not a full operating system but is a form of middleware that rests between the OS and the application. For example, the first version of Microsoft Windows, Windows 1.0, was not a full operating system, but a GUI laid over DOS. DBMSs include MySQL, PostgreSQL, Microsoft SQL Server, Oracle System Utilities : Disk cleaners, defragmentation tools, Disk Error checking tools, Performance monitors: Memory, Hard disk, CPU Security : Firewalls, Virus guards Translators: Compiler, Interpreter, decompiler
- Business : management information system software that access one or more large database containing business information Embedded software: Embedded software resides in read-only memory and is used to control product and system for the customer and industrial markets Web-based software: The network becomes a massive computer providing an almost unlimited software resources that can be accessed by anyone with a modem. Artificial intelligence software: AI software makes use of non-numerical algorithms to solve the complex problems that are not amenable to computing or straightforward analysis scientific software: They have been characterized by number crunching algorithms
