Abstract. The Evolutionary Geometric Near-neighbor Access Tree (EGNAT) is a recently proposed data structure that is suitable for indexing large collections of complex objects. It ...
B-tree and index into two layers of abstraction. In addition, this paper provides algorithms for (i) concurrency control and recovery including locking of individual keys and of co...
Abstract. To achieve acceptable query response times in data warehouse environments, the data have to be pre-aggregated according to the need of the applications and stored redunda...
—We present a scheme for view-dependent level-of-detail control that is implemented entirely on programmable graphics hardware. Our scheme selectively refines and coarsens an ar...
Abstract. In this paper we present new concurrent and recoverable B-link-tree algorithms. Unlike previous algorithms, ours maintain the balance of the B-link tree at all times, so ...
