Join spaces , soft join spaces and lattices
The aim of this paper is to initiate and investigate new (soft) hyperstructures, particularly (soft) join spaces, using important classes of lattices: modular and distributive. They are used in order to study (soft) hyperstructures constructed on the set of all convex sublattices of a lattice.
متن کاملSpatial Join
DEFINITION Spatial join operation is used to combine two or more datasets with respect to a spatial predicate. The predicate can be a combination of directional, distance, and topological spatial relations. In the case of nonspatial joins, the joining attributes must be of the same type, but for spatial joins they can be of different types. Usually each spatial attribute is represented by its m...
متن کاملJoin Constraints
Many application domains involve constraints that, at a conceptual modeling level, apply to one or more schema paths, each of which involves one or more conceptual joins (where the same conceptual object plays roles in two relationships). Popular information modeling approaches typically provide only weak support for such join constraints. This paper contrasts how join constraints are catered f...
متن کاملClone Join and Shadow Join: Two Parallel Algorithms for Executing Spatial Join Operations
With the growing popularity of spatial applications, there has been a signiicant increase in the use of database systems for storing and querying spatial data. Spatial data is now readily available from a variety of sources including government mapping agencies, commercial sources, satellite images, and simulation outputs. As this trend continues, applications continue to execute increasingly c...
متن کاملCyclo-Join: A Join that Spins without Getting Dizzy
By leveraging modern networking hardware (RDMA-enabled network cards), we can shift priorities in distributed database processing significantly. Complex and sophisticated mechanisms to avoid network traffic can be replaced by a scheme that takes advantage of the bandwidth and low latency offered by such interconnects. We illustrate this phenomenon with cyclo-join, an efficient join algorithm ba...
