An UML Approach to Overcome Issues of Concurrency in Distributed SystemsKeywords: Dead Locks , Starvation , Mutual Exclusion , Communincation , Time , Heterogenity , Token Passsing , Centralized Approach Abstract: A Distributed System is a collection of Independent Computers that appears to its Users’ as a single entity or Single System. These Independent Systems collaborate together to achieve a common goal. They communicate with each other via a network. Concurrency is one common characteristic of Distributed Systems. They help in achieving parallelism. There are issues of Concurrency in Distributed Systems. The main intention of this research is to uncover the issues of Distributed Systems in its design phase so that the cost incurred in the later stages for detecting and rectifying those issues can be reduced. This paper discusses the issues of concurrency in Distributed System and proposes a model that overcomes the issues. Generally Distributed Systems are modeled using Deployment Diagrams but in this paper we discuss the drawbacks of using Deployment diagram in showing concurrency in Distributed System and we provide a model using the Object Diagrams that overcomes the listed Drawbacks.
