Computers and networks, smartwatches, vehicles, smartphones, video games and the myriad of apps that fill our lives every day – all depend on software. These digital gadgets and others are the result of software developers. They are the brains behind these programs.
Software development is the process that creates an application from the initial idea to its release. It is a systematic process that starts with a thorough requirements analysis, which transforms user requirements and desires into a fully functional software system. The steps that are involved in the process are laid out in the Software Development Life Cycle (SDLC). The framework’s strict adherence allows developers to develop superior software that is more reliable, less cost and shorter time to produce than other methods.
Every software development project has to include testing. It helps ensure that applications are working as per specifications and are free from defects. Based on the scope of the application it could include functional testing, regression, compatibility, and load testing.
Performance testing is used to determine the application’s response time in both peak and normal load conditions, and its ability to scale. It determines the capacity of the network and hardware required to host an application.
The latest technologies that require sophisticated software programming are continually emerging and bringing more demand for developers. Internet of Things, where devices such as cars, homes and industrial equipment communicate via sensors and microprocessors. Also artificial intelligence-powered software that allows software to complete tasks like mimicking decision-making and learn.
