Design And Implement Of A Distributed Computing Scheme Based On UML And Design Patterns

One flavor of distributed computing has received a lot of attention lately, and it will be a primary focus of this situation--an environment where you can harness conveniently idle resourses of hundreds, or thousands of networked systems to work together on a particularly processing-intensive problem which only can be accomplished by super computer before. At present and in the predictable future distributed computing will be an active and promising domain.The purpose of this paper is giving a distributed computing scheme which is simple in concept and can be used expediently. And exspecially it is a scheme which has no relations with the concrete task.Based on the study of traditional distributed processing technology and other software technology the paper brought forward a concise solution to build the platform. After the basic theories of OOP(Object Oriented Programming) and UML(Unified Modeling Language) are introduced, by using Object Oriented method the distributed computing platform is analyzed and designed using UML as a tool, several kinds of diagram and detailed documentation are given. This paper adopts some design pattern that has been proved to be efficacious in practice process, which makes design clear and design time shorter. Owing to those technologies the system get good reusability and agility simultaneously and it is convenient to be extended.After the system was coded and tested, the usage of the platform was introduced in detail. Finally as examples two experimental program was developed, the result and conclusion was given. According to the practice and it's result the distributed computing platform satisfies the anticipant request and has good effectivity.
