  • Abstract
Distributed database system technology is one of the major developments in information technology area. It will continue to have a very significant impact on data processing in the upcoming years because distributed database systems have many potential advantages over centralized systems for geographically distributed organizations. The continuing interest in distributed database systems in the research community and the marketplace and the introduction of many commercial products indicate that distributed database systems will play a more important role in data processing and eventually will replace centralized systems as the major database technology in the future. The availability of high speed communication networks and, especially, the phenomenal popularity of the Internet and the intranets will undoubtedly speed up the transition process. Some challenging problems must be solved before the full potential benefits of distributed database technology can be realized. Among them is query processing (including query optimization), one of the most important issues in distributed database system design. The query optimization problem in large-scale distributed databases is NP-hard in nature and difficult to solve. In this study, the query optimization problem is reduced to a join ordering problem similar to a variant of traveling salesman problem. We explored several heuristics and a genetic algorithm for solving the join ordering problem. Some computational experiments on these algorithms were conducted and solution qualities compared. The computation experiments show that heuristics and genetic algorithms are viable methods for solving query optimization problem in large scale distributed database systems.
