The advantages research about the SSHDWR+AJax design pattern in software developmen

At present, the framework distributed applications with its good characteristics of high cohesion, low coupling, high elastic, and easy maintenance obtained the people´s extensive concern, it based on the layers of software development, especially Struts, Spring, and Hibernate framework. The integrated SSHDWR + AJax composite frame is Designed, the design is givened that the presentation layer, the business logic and the data persistence layer. It provides a design pattern with the loose coupling, the high reliability, the easy expansion, the low development cost, the short development cycle for the development of software system.
