Database replication based on group communication systems has recently been proposed as an efficient and resilient solution for large-scale data management. However, its evaluati...
This paper presents an architecture for resource sharing in Personal Networks (PNs). Resources are not necessarily in the same authentication domain and the group that uses them is...
In this paper, we consider a generic model of computational grids, seen as several clusters of homogeneous processors. In such systems, a key issue when designing efficient job al...
Query optimization is used frequently in relational database management systems. Most existing techniques are based on reordering the relational operators, where the most selective...
Multidimensional aggregation queries constitute the single most important class of queries for data warehousing applications and decision support systems. The bottleneck in the ev...
