Astrid C. Schauss,Heidi M. McBrideerepresentation, organization, query processing and optimization..Due to the complexity and volume of spatial datasets, access methods are required to guarantee acceptable query processing performance. Usually, spatial access methods work on object approximation instead of the detailed object spatial报复 发表于 2025-3-30 14:49:24

Indu S. Ambudkar,Hwei L. Ong,Brij B. Singhil from the spatial database perspective; algorithms, analys.Modern applications are both data and computationally intensive and require the storage and manipulation of voluminous traditional (alphanumeric) and nontraditional data sets (images, text, geometric objects, time-series). Examples of such任意 发表于 2025-3-30 23:18:21

Jennifer H. Gromek,Arik Dvircase, and a number of very efficient methods have been proposed. However, in a distributed database system we have to take into consideration the communication overhead, in addition to the CPU and I/O cost, especially when the size of each object is not negligible. Four query evaluation strategies wfigment 发表于 2025-3-31 06:03:34
