Software development is the processes which involves creating software programs, representing all the steps throughout the Systems Development Life Cycle (SDLC). By creating software programs can improve design, product management, and project management. It is also known as a Software Development Life Cycle (SDLC). SDLC technologies support the design of software to meet a business need, the development of software to meet the specified design and the distribution of software to production.
The waterfall model, the original SDLC method generally follows these steps in order:
• Identification of software
• Analysis of the software specification
• Detailed information of the software requirements
• Software design
• Programming of software required
• Testing of Software
• Maintenance of Software
1) Identification of software
These ideas of Identification of need can come from market research including new customers, existing customers, sales prospects, other internal software development staff. 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.
Planning is the main objective of each and every activity/phase, where we have to discover things that belong to the project. An important step in creating a software program is to extract the requirement analysis.
Once the requirements are specified, the design of the software can be established in a software design document. This involves high-level design of the main modules with an overall picture (such as a block diagram) of how they fit together.
4) Implementation, Testing and Documenting
Software Development includes Implementation, testing and documenting and Software testing is an integral and important steps of the software development process.
5) Deployment and maintenance
Deployment is directly start after whole the code is tested, which is approved for release and sold or otherwise distributed into a production environment. This involves installation, customization, testing, and possibly an extended period of evaluation. Maintenance involves maintain all the processes which comes under the phases of Software Development.
