What are Software Design Principles?
Software design principles represent a set of guidelines that helps us to avoid having a bad design. The design principles are associated to Robert Martin who gathered them in “Agile Software Development: Principles, Patterns, and Practices”. According to Robert Martin there are 3 important characteristics of a bad design that should be avoided: • Rigidity – It is hard to change because every change affects too many other parts of the system. • Fragility – When you make a change, unexpected parts of the system break. • Immobility – It is hard to reuse in another application because it cannot be disentangled from the current application.
