What lies behind the concept of refactoring to patterns?
It implies the transformation of existing applications according to software design patterns. A pattern is based on an abstraction of a group of similar software designs that is further refined and at the end constitutes a model that contains the most relevant characteristics of the original applications. Patterns are obtained with a logical inductive process that has been applied to real-life application designs. Software design patterns are also enriched with good design principles and standards that will allow the user to obtain a better product when the pattern is applied. Patterns can assist users with creating large-scale applications and with resolving recurring design problems with proven and highly effective guidance. When an application is refactored according to design patterns, the resulting structure of the application can be understood as a derivation of the pattern(s) applied; this reduces the future development and maintenance risks.
