| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | While the optimality of a query optimizer has a significant impact on performance of a database system, a systematic evaluation methods of the optimality has not been sufficiently studied yet. In this paper, we discuss indices for evaluating the optimality of query execution plan generation based on experimental results. | |
