| Abstract: |
The new era of business intelligence and web data warehousing has brought in new research and development issues, whereby it is imperative to have an efficient refresh process for the information in the XML warehouses. Existing strict real-time or static timestamp-based refresh mechanisms are no always efficient. In this paper, we propose to build a waiting queue to make the XML warehouse refresh processes discrete, base on (i) Level of Criticality (LoC), (ii) Impact on Reports (IoR), and (iii) Frequency of Appearance (FoA). Our experimental results have shown the effectiveness of our proposed method.
