dc.description.abstract | Concurrency control, distribution design, and query processing are some of the important issues in the design of distributed databases. In this paper, we have studied these issues with respect to a relational database on a local computer system connected by a multi-access broadcast bus. A broadcast bus allows information to be distributed efficiently, and hence simplifies the solutions to some of these issues. A transaction model that integrates the control strategies in concurrency control and query processing is proposed. In concurrency control, the lock, unlock, and update of data are achieved by a few broadcasts. A dynamic strategy is used in query processing, as less data are transferred when compared to a static strategy. The status information needed in dynamic query processing can be conveniently obtained by broadcasting. Lastly, some NP-hard file placement problems are found to be solvable in polynomial time when updates are broadcast | en_US |
