Advancement in information technology has been tremendous in the recent years. Distributed computing concepts are being applied to the database systems as well, leading to the development of distributed databases.[5] A distributed database is a collection of multiple logically interrelated databases distributed over a computer network. With the making of distributed databases rose the problem of deadlocks, concurrency and management of databases. In an operating system, a deadlock is a situation which occurs when a process enters a waiting state because a resource requested by it is being held by another waiting process, which in turn is waiting for another resource.[4] If a process is unable to change its state indefinitely because the resources requested by it are being used by another waiting process, then the system is said to be in a deadlock.Concurrency refers to the process of simultaneous accesses to the database by various processes. One needs to synchronize the accesses to ensure consistency and avoid deadlocks.[4] In this paper, we discuss the various deadlock detection techniques and explain a new approach developed to detect and solve deadlocks.
