The term application development is often used to refer to the activity of computer programming, which is the process of writing and maintaining the source code, whereas the broader sense of the term includes all that is involved between the conception of the desired application through to the final manifestation of that application. Therefore, application development may include research, new development, modification, reuse, re-engineering, maintenance, or any other activities that result in the finished application.
