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 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 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...
متن کاملFinding Superior Skyline Points from Incomplete Data
The skyline query has proven to be an important tool in multi-criteria decision making and search space pruning. A skyline query returns the subset of points from a multidimensional dataset that are not dominated by any other point. Due to its wide applications, skyline query and its variants have been extensively studied in the past. However, skyline computation for incomplete domain, where po...
