| Abstract: | The emergence and extensive application of design patterns provide an effective way to achieve high cohesion and low coupling of software modules.Observer pattern is a pattern that reduces the coupling of software modules.The application of Observer pattern may help to develop the information system agilely.The paper introduces the basic theory of Observer pattern as well as its implementation method,discusses the active role it plays in improving software expansibility and adaptability by describing the application of Observer pattern in the development of Alarm Processing System.At last,the application advantages and disadvantages of Observer pattern in software design are analyzed. |
