On Modeling and Analysis of Multidimensional Geographic Databases
نویسنده
چکیده
A Data Warehouse is a centralized repository of data acquired from external data sources and organized following a multidimensional model (Inmon, 1996) in order to be analyzed by On-Line Analytical Processing (OLAP) applications. OLAP tools provide the ability to interactively explore multidimensional data presenting detailed and aggregated data. The results of analyses are the basis of strategic business decisions. It has been estimated that about 80% of data in databases contains geo-referenced information (Franklin, 1992). Geographic Information Systems (GISs) allow memorizing, analyzing and visualizing geographic data. OLAP systems reduce geographic data to simple textual data. Therefore, they do not present any carABSTRACT

متن کاملA Web-Based Tool for Spatio-Multidimensional Analysis of Geographic and Complex Data
Spatial OLAP (SOLAP) integrates spatial data into OLAP systems, and SOLAP models define spatial dimensions while measuring spatio-multidimensional operators. In this paper, the author presents the concepts of geographic and complex measures that allow integrating geographic and complex information as subjects of analysis in spatial data warehouses. The concept of geographic measure extends the ...
متن کاملOn the Requirements for User-Centric Spatial Data Warehousing and SOLAP
Data warehouses and OLAP systems help to analyze complex multidimensional data and provide decision support. With the availability of large amounts of spatial data in recent years, several new models have been proposed to enable the integration of spatial data in data warehouses and to help analyze such data. This is often achieved by a combination of GIS and spatial analysis tools with OLAP an...
متن کاملSpatiotemporal Data Modeling and Management: A Survey
Many data objects in the real world have attributes about location and time. Such spatiotemporal objects can be found in applications such Geographic Information Systems (GIS), environmental data management and multimedia databases. Traditional relational database technology is not suitable for managing spatiotemporal data, which are multi-dimensional with complex structures and behaviors. Spat...
