Skyline query processing
This thesis deals with a special subset of multi-dimensional set of points, called the Skyline. These points are the maxima or minima of the complete set and are of special interest for the field of decision support. Coming from basic algorithms for computing the Skyline we will develop ideas and algorithms for “on-the-fly” or online computation of the Skyline. We will also extend the concept o...
متن کاملMulti-Dimensional Skyline Query Processing
Introduction In many applications, a huge number of geometric, geographic or spatial objects are need to be stored, managed, and retrieved. As examples, some of the traditional applications are listed as follows: • Geographic Information Systems (GIS), which help users to organize their work in many areas, including military applications, environmental information systems, urban planning and so...
متن کاملSkyMap: A Trie-Based Index Structure for High-Performance Skyline Query Processing
Skyline queries have become commonplace in many applications. The main problem is to efficiently find the set of Pareto-optimal choices from a large amount of database items. Several algorithms and indexing techniques have been proposed recently, but until now no indexing technique was able to address all problems for skyline queries in realistic applications: fast access, superior scalability ...
متن کاملAGiDS: A Grid-Based Strategy for Distributed Skyline Query Processing
Skyline queries help users make intelligent decisions over complex data, where different and often conflicting criteria are considered. A challenging problem is to support skyline queries in distributed environments, where data is scattered over independent sources. The query response time of skyline processing over distributed data depends on the amount of transferred data and the query proces...
متن کاملA Survey of Skyline Query Processing
Living in the Information Age allows almost everyone have access to a large amount of information and options to choose from in order to fulfill their needs. In many cases, the amount of information available and the rate of change may hide the optimal and truly desired solution. This reveals the need of a mechanism that will highlight the best options to choose among every possible scenario. B...
