<programming> (RAD) A loose term for any software life-cycle designed to give faster development and better results and to take maximum advantage of recent advances in development software. RAD is associated with a wide range of approaches to software development: from hacking away in a GUI builder with little in the way of analysis and design to complete methodologies expanding on an information engineering framework. Some of the current RAD techniques are: CASE tools, iterative life-cycles, prototyping, workshops, {SWAT teams}, timebox development, and Re-use of applications, templates and code. {RAD at BSO/Den Haag (http://riv.nl/origin/company/denhaag/RAD.HTM)}. ["Rapid Application Development", James Martin]. (1995-09-23)

Rapid application development (RAD), also called rapid application building (RAB), is both a general term for adaptive software development approaches, and the name for James Martin's method of rapid development. In general, RAD approaches to software development put less emphasis on planning and more emphasis on an adaptive process.

An application program (software application, or application, or app for short) is a computer program designed to carry out a specific task other than one relating to the operation of the computer itself, typically to be used by end-users. Word processors, media players, and accounting software are examples.

application program

<programming, operating system> (Or "application", "app") A complete, self-contained program that performs a specific function directly for the user. This is in contrast to system software such as the operating system kernel, server processes, libraries which exists to support application programs and utility programs. Editors for various kinds of documents, spreadsheets, and text formatters are common examples of applications. Network applications include clients such as those for FTP, electronic mail, telnet and WWW. The term is used fairly loosely, for instance, some might say that a client and server together form a distributed application, others might argue that editors and compilers were not applications but utility programs for building applications. One distinction between an application program and the operating system is that applications always run in {user mode} (or "non-privileged mode"), while operating systems and related utilities may run in supervisor mode (or "privileged mode"). The term may also be used to distinguish programs which communicate via a graphical user interface from those which are executed from the command line. (2007-02-02)

<programming> (SDLC) Any logical process used by a {systems analyst} to develop an information system, including requirements, validation, training, and user ownership. An SDLC should result in a high quality system that meets or exceeds customer expectations, within time and cost estimates, works effectively and efficiently in the current and planned Information Technology infrastructure, and is cheap to maintain and cost-effective to enhance. {US DOJ SDLC (http://usdoj.gov/jmd/irm/lifecycle/table.htm)}. (2000-12-24)

In systems engineering, information systems and software engineering, the systems development life cycle (SDLC), also referred to as the application development life-cycle, is a process for planning, creating, testing, and deploying an information system.SELECTING A DEVELOPMENT APPROACH.

Il rapido sviluppo (The Rapid Development) is an apostolic letter signed by Pope John Paul II on 24 January 2005; it mainly addresses those who are involved in communications.
