LDT: a Logarithmic Distributed Search
- …We propose LDT, a new Scalable Distributed Search Tree for the dictionary problem, as an alternative to both random trees and deterministic height balanced trees. Our scheme exhibits logarithmic update time, either constant or logarithmic search time for single key queries and output sensitive query…

DSL: Accommodating Skip Lists in the SDDS Model
- …We propose DSL, a new Scalable Distributed Data Structure for the dictionary problem, based on a version of Skip Lists, as an alternative to both random trees and deterministic height balanced trees. Our scheme exhibits, with high probability, logarithmic search time, constant reconstruction time…

Categorical Range Queries in Large Databases
- …In this pape r e int r duce the categor214 (a.k.a. chr omatic) r) ge quer2L (CRQs) in the context oflar1P disk-r esident data sets, motivated by the fact that CRQsar conceptually simple and emer4 often in DBMSs. On the basis of spatial data str uctur3N and R-tr4L in par ticular e p r pose a multi-tr…

LR-tree: a Logarithmic Decomposable Spatial Index Method
- …this paper, we present LR-trees, a new efficient scheme for dynamic manipulation of large datasets, which combines the search performance of the bulkloaded R-trees with the updated performance of R # -trees. Experimental results provide evidence on the latter statement and illustrate the superior…

Signature-based Structures for Objects with Set-valued Attributes
- …Aiming at the efficient retrieval of objects with set-valued attributes, we introduce three variations of a new method in order to satisfy subset and superset queries. Our approach is to combine the advantages of two access methods, that of linear Hashing and of tree-shaped methods, on which other s…
