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 کاملProcessing Skyline Queries in P2P Systems
Efficient query processing in P2P systems poses a variety of challenges mainly resulting from the strict decentralization and limited knowledge. Particularly with regard to queries involving ranking, top-N or skylines, existing approaches for centralized systems cannot be applied easily to P2P environments. In this paper, we focus on the problem of efficiently processing skyline queries in larg...
متن کاملWithin Skyline Query Processing in Dynamic Road Networks
The continuous within skyline query is an important type of location-based query, which can provide useful skyline object information for the user. Previous studies on processing the continuous within skyline query focus exclusively on a static road network, where the object attributes and the conditions of roads remain unchanged. However, in real-world applications, object attributes and road ...
متن کاملEfficient Parallel Skyline Query Processing for High-Dimensional Data
Given a set of multidimensional data points, skyline queries retrieve those points that are not dominated by any other points in the set. Due to the ubiquitous use of skyline queries, such as in preference-based query answering and decision making, and the large amount of data that these queries have to deal with, enabling their scalable processing is of critical importance. However, there are ...
متن کاملDistributed Spatial Skyline Query Processing in Wireless Sensor Networks
Spatial skyline queries can be used in wireless sensor networks for collaborative positioning of multiple objects. However, designing a distributed spatial skyline algorithm in resource constrained wireless environments introduces several research challenges: how to distribute the computation of distances to multiple events in order to compute the skylines efficiently, accurately, quickly, prog...
