Computers, networks, smartwatches, smartphones, vehicles, video games and the countless apps that fill our lives rely on software to function. These digital products and many others are the creations of software developers. They are the creators behind these programs.
Software development is a process that creates an application from the initial idea to the point of release. It is a method of development that starts with a thorough needs analysis, then transforming the user’s desires and needs into a functioning software system. The Software Development Life Cycle (SDLC) defines the steps in this process. Adherence to this framework allows developers to develop software with higher quality as well as lower costs and shorter time to produce than other methods.
Every software development endeavor must include testing. It ensures that the applications work in accordance with specifications and are not prone to errors. This may include functional testing, regression testing, compatibility testing and load tests depending on the scope of the application.
Performance testing is used to determine an application’s performance time under normal and peak load conditions, and its capacity to scale. It is used to determine the hardware and network capacity required to host an application.
The demand for software developers is growing as new technologies are created that require sophisticated programming. Examples include the internet of things, which lets devices such as cars, homes and industrial machines are connected via sensors and microprocessors, as well in artificial intelligence-powered programming that lets software perform tasks like emulating human decision-making and learning.
