Analysis of Implementation of Distributed Database using Colored Petri Nets (CPN)

Abstract

As internet is everything nowadays, the need for storing the information and retrieving the information from different locations is very difficult. To overcome this problem the concept of distributed database came into existence. Here the copy of data is stored in different locations and time required to retrieve data from those locations is less. In this paper we describe communication in the distributed system among some managers. Here the managers should save their database unique. Whenever there is an update it should be reflected to remaining managers in the system and inform them to perform the same update. Here we illustrate three basic concepts i.e., concurrency, conflict and causal dependency. This idea is implemented using the concept colored petri nets (CPN). The implementation of this is analyzed by the software called CPN tool which uses Colored Petri Net ML for assertions and net impressions. This paper also consists of the case study of distributed database and explains the colored petri net concept.
