The performance of data-parallel algorithms for spatial operations using data-parallel variants of the bucket PMR quadtree, R-tree, and R+-tree spatial data structures is compared...
As video data is penetrating many information systems the need for database support for video data evolves. In this paper we present a generic data model that captures the structu...
We address the problem of finding parallel plans for SQL queries using the two-phase approach of join ordering followed by parallelization. We focus on the parallelization phase a...
Advanced technical applications like routing systems or electrical network managementsystems introduce the need for complex manipulations of large size graphs. Efficiently support...
MapBase is a laboratory information system that has been supporting a high-throughput genome-mapping operation for the last three years. We chose to build MapBase around a C++-bas...
