An evaluation of sampling-based size estimation methods for selections in database systems

The results of a performance study of the representative sampling-based size estimation methods in database management systems are reported in this paper. Major performance measurement includes estimation accuracy, the amount of sample taken, and the coverage. The impact of skewed data on the performance is also discussed. These results allow a better understanding and assessment of sampling estimation methods and determine the suitability of different methods under different situations.<>
