Software Design refers to the process of conceiving, specifying, documenting, and creating the underlying structure of a software or system. It involves coding, which is a key task performed by professional programmers who translate design concepts into a functional application. The category also includes aspects of application design, a practice that conceptualizes the visual and interactive elements of an application, often executed by application developers. The term 'Michael Kappel' could refer to a notable figure in this field, possibly a renowned software designer or programmer. The category also encompasses programmers and people as software design is a human-centric field, requiring a team of skilled individuals for execution.
