To avoid tuning, we propose a reasonable default value for the disk-buffer size with a small and acceptable performance loss. The experimental results validate our arguments.

Near Real-Time Data Warehousing Using State-of-the-Art ETL Tools,reshment can no longer be performed in off-peak hours only. In particular, the source data may be changed concurrently to data warehouse refreshment. In this paper we show that anomalies may arise under these circumstances leading to an inconsistent state of the data warehouse and we propose approaches to avoid refreshment anomalies.
