Software Web Development Scenario What is Web Programming? Programming is the intricate art of telling a computer what to do. "You mean when I say, ‘Give me back my research paper you stupid machine’, that I’m programming". Oops, no. Programming is giving written instructions in a logical manner that the computer can understand. Essentially, you give the computer small steps of instructions, and the computer goes down the list, executing each one in order. Programming allows you to make new software and have the computer do new things. Web site programming is the same except you write applications or web pages that are used by a web browser. The good news is that web site programming can be easy! This page will help you understand, what is programming, and why you might want to do web site programming. Web Site Programming is the practice of writing applications that run on a web server and can be used by many different people. Many applications work really well as a web application. Some examples of popular web applications include Flickr, Gmail, and Google Maps. You are able to upload and view pictures, send email and lookup directions using these web applications and they are all made possible through web site programming. Web development is a broad term for the work involved in developing a web site for the Internet (World Wide Web) or an intranet. Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services. A more comprehensive list of tasks to which web development commonly refers, may include web design, web content development, client liaison, client-side/server-side scripting, web server and network security configuration, and e-commerce development. Among web professionals, "web development" usually refers to the main non-design aspects of building web sites: writing markup and coding. For larger organizations and businesses, web development teams can consist of hundreds of people (web developers). Smaller organizations may only require a single permanent or contracting webmaster, or secondary assignment to related job positions such as a graphic designer and/or information systems technician. Web development may be a collaborative effort between departments rather than the domain of a designated department. The World Wide Web has become a major delivery platform for web development a variety of complex and sophisticated enterprise applications in several domains. In addition to their inherent multifaceted functionality, these web applications exhibit complex behavior and place some unique demands on their usability, performance, security and ability to grow and evolve. However, a vast majority of these applications continue to be developed in an ad-hoc way, contributing to problems of usability, maintainability, quality and reliability. While web development can benefit from established practices from other related disciplines, it has certain distinguishing characteristics that demand special considerations. In recent years of web development there have been some developments towards addressing these problems and requirements. As an emerging discipline, web engineering actively promotes systematic, disciplined and quantifiable approaches towards successful development of high-quality, ubiquitously usable web-based systems and applications. In particular, web engineering focuses on the methodologies, techniques and tools that are the foundation of web application development and which support their design, development, evolution, and evaluation. Web application development has certain characteristics that make it different from traditional software, information system, or computer application development. Web development takes into account many security considerations, such as data entry error checking through forms, filtering output, and encryption. Malicious practices such as SQL injection can be executed by users with ill intent yet with only primitive knowledge of web development as a whole. Scripts can be exploited to grant unauthorized access to malicious users trying to collect information such as email addresses, passwords and protected content like credit card numbers.
