Toward Better Support for Spatial Decision Making: Defining the Characteristics of Spatial On-line Analytical Processing (solap)

چکیده
To exploit the full potential of the spatial and temporal dimensions of a data warehouse, new tools are needed. It has been shown that OLAP possesses a certain potential to support spatio-temporal analysis. However, without a spatial interface for viewing and manipulating the geometric component of the spatial data, the analysis may be incomplete. A new category of OLAP tools, SOLAP (Spatial OLAP) tools, is presented. SOLAP tools are defined and the associated concepts are presented. A series of essential features, as well as desirable characteristics, are then described. Finally, application prototypes are described and an example of spatio-temporal analysis is presented.

It is well known that transactional and analysis systems each require a different database structure. In general, the database structure of transactional systems is optimized for consistency and efficient updates while the database structure of analysis systems is optimized for complex query performance. Non-spatial data are reorganized in data warehouses in order to support analysis and decisi...
