Physical Data Modeling for Multidimensional Access Methods
Despite the fact that the database community has proposed a vast number of indexing methods over the years, no standard physical data model has been established like it has been achieved on the conceptual and logical level. How to optimize a given data model by using various indexing methods is still the ‚trade secret‘ of the database administrators. Only recently, some approaches have been tri...
متن کاملEecient Access Methods for Multidimensional Data
Interest in multidimensional data has been steadily rising in the database community. Storage and subset retrieval of multi-dimensional data is necessary for scienti c, geographic, temporal and business data. Our research has concentrated on developing techniques for e cient loading, retrieval, and update of multi-dimensional data. Current commercial systems (with the exception of one) do not s...
متن کاملMultidimensional Access Methods: Trees Have Grown Everywhere
This paper is a survey of work and issues on multidimensional search trees. We provide a classification of such methods, we describe the related algorithms, we present performance analysis efforts, and finally outline future research directions. Multi-dimensional search trees and Spatial Access Methods, in general, are designed to handle spatial objects, like points, line segments, polygons, po...
متن کاملZoning Multidimensional Access Methods for Analytical Database Applications
In emerging analytical database applications that deal with large sets of multidimensional static data sets, the performance of the query system significantly depends on the performance of its access methods and the underlying disk system. In recent years, hard disks are manufactured with multiple physical zones, where seek times and data transfer rates vary significantly across the zones. Howe...
متن کاملLocality of Corner Transformation for Multidimensional Spatial Access Methods
The geometric structural complexity of spatial objects does not render an intuitive distance metric on the data space that measures spatial proximity. However, such a metric provides a formal basis for analytical work in transformation-based multidimensional spatial access methods, including locality preservation of the underlying transformation and distance-based spatial queries. We study the ...
