System modeling is widely used in all aspects of modern life. In today's Internet era, complex distributed systems play an important role in modern production. The purpose of this paper is to study the application of UML language in distributed system modeling. Firstly, it discusses the importance of distributed system software model from a scientific point of view, considers the definition of distributed system, discusses the theoretical basis and development requirements of distributed test system development, and puts forward a scientific model. Comprehensive application of unified modeling language UML, combined with CORBA distributed computing technology to build a distributed test system modeling. Analyze system components and extended views, and implement a grade management module. It can be concluded that the modeling method in this paper is an effective method, which provides a reference for the development of the distributed examination system.
