Properties of Design Patterns 1002 18 A pattern addresses a recurring design problem that arises in specific design situations,and presents a solution to it. a Patterns document existing,well-proven design experience. Patterns provide a common vocabulary and understanding for design principles. Patterns are a means of documenting software architectures. Patterns support the construction of software with define properties. Patterns help you to manage software complexity. Institute of Computer Software 2022-2-27 Nanjing University
