Query processing in spatial databases containing obstacles
Despite the existence of obstacles in many database applications, traditional spatial query processing assumes that points in space are directly reachable and utilizes the Euclidean distance metric. In this paper, we study spatial queries in the presence of obstacles, where the obstructed distance between two points is defined as the length of the shortest path that connects them without crossi...
متن کاملQuery Processing in Spatial Databases
IntroductIon Spatial data management has been an active area of intensive research for more than two decades. In order to support spatial objects in a database system several important issues must be taken into account such as: spatial data models, indexing mechanisms and efficient query processing. A spatial database system (SDBS) is a database system that offers spatial data types in its data...
متن کاملQuery Processing in Spatial Network Databases
Despite the importance of spatial networks in real-life applications, most of the spatial database literature focuses on Euclidean spaces. In this paper we propose an architecture that integrates network and Euclidean information, capturing pragmatic constraints. Based on this architecture, we develop a Euclidean restriction and a network expansion framework that take advantage of location and ...
متن کاملAn Approach to Query Processing in Homogenously Distributed Spatial Databases
Query processing in distributed environment is basic need of many organizations in order to process huge amount of data in less amount of time. There are many approaches provided for parallel query processing in distributed environment. This paper presents the approach which does the parallel query processing in 4 steps. Firstly query fragmentation is done by using SQL parsing, then query redir...
متن کاملApproximate Query Processing in Spatial Databases Using Raster Signatures
Traditional query processing provides exact answers to queries. However, in many applications, the response time of exact answers is often longer than what is acceptable. Approximate query processing has emerged as an alternative approach to give to the user an answer in a short time. The goal is to provide an estimated result in one order of magnitude less time than the time to compute the exa...
