Web Application Development

Software development is the development of a software product. The term “software development” may be used to refer to the activity of computer programming, which is the process of writing and maintaining the source code, but in a broader sense of the term it includes all that is involved between the conception of the desired software through to the final manifestation of the software, ideally in a planned and structured process. Therefore, software development may include research, new development, prototyping, modification, reuse,re-engineering, maintenance, or any other activities that result in software products.Software can be developed for a variety of purposes, the three most common being to meet specific needs of a specific client/business , to meet a perceived need of some set of potential users , or for personal use. Embedded software development, that is, the development of embedded software such as used for controlling consumer products, requires the development process to be integrated with the development of the controlled physical product. The need for better quality control of the software development process has given rise to the discipline of software engineering, which aims to apply the systematic approach exemplified in the engineering paradigm to the process of software development.

The sources of ideas for software products are legion. These ideas can come from market research including the demographics of potential new customers, existing customers, sales prospects who rejected the product, other internal software development staff, or a creative third party. Ideas for software products are usually first evaluated by marketing personnel for economic feasibility, for fit with existing channels distribution, for possible effects on existing product lines, required features, and for fit with the company’s marketing objectives. In a marketing evaluation phase, the cost and time assumptions become evaluated. A decision is reached early in the first phase as to whether, based on the more detailed information generated by the marketing and development staff, the project should be pursued further.

Consistency in Software

In order to ensure that software can evolve in a way that maintains its inherent multi – dimensionality, one must ensure that the different dimensions evolve together in a consistent manner. Software has too many dimensions to combine within a single framework. A good mechanism should not be geared to a specific problem such as ensuring the consistency of a UML class diagram with the source code. Instead it should be flexible enough to handle the broad range of dimensions that are actually involved in software development.
