Efficient Query Processing in Geographic Information Systems by Beng Chin Ooi

By Beng Chin Ooi

This monograph describes equipment for extending relational database platforms for geographic functions. The ways that a relational database procedure is supplemented with unconventional spatial indexing constructions, extra spatial subsystems and question processors are defined in nice aspect. The paintings provides an intensive survey of current spatial indexing innovations and a taxonomy of the extensions to the multidimensional indexing buildings. an intensive experimental research of spatial indexes is gifted. The paintings covers the next components: - the layout of geographic details structures (GIS) - prolonged question languages for GIS - spatial indexing mechanisms - question processing concepts. the writer provides his personal skd-trees and prolonged question optimization options. The survey of spatial indexing constructions for non-zero sized items presents a framework for employees within the box of spatial info platforms to judge spatial entry tools. the dignity of question optimization will help figuring out of the position of that subject in GIS.

Modular Ontologies: Concepts, Theories and Techniques for Knowledge Modularization

This publication constitutes a suite of study achievements mature sufficient to supply an organization and trustworthy foundation on modular ontologies. It provides the reader a close research of the cutting-edge of the examine zone and discusses the new options, theories and strategies for wisdom modularization.

Advances in Object-Oriented Data Modeling

Until eventually lately, info structures were designed round diverse enterprise services, similar to debts payable and stock regulate. Object-oriented modeling, against this, constructions structures round the data--the objects--that make up a few of the enterprise features. simply because information regarding a selected functionality is restricted to 1 place--to the object--the approach is protected against the results of switch.

Introduction To Database Management System

Designed particularly for a unmarried semester, first direction on database structures, there are four elements that differentiate our booklet from the remaining. simplicity - in general, the expertise of database platforms could be very obscure. There are

2010). 2 Advanced CSP Approaches On the basis of the static CSP approach, numerous extensions have been implemented in order to improve expressiveness and the efficiency of the underlying reasoning algorithms. An in-depth analysis of existing CSP variants is beyond the scope of this book; however, we will now discuss some representative ones that have found their way into commercial configuration environments. Dynamic Constraint Satisfaction Configuration tasks very often include variables that do not have to be taken into account in specific configuration contexts.
