QuadR-tree indexing selection engine for tuning spatial database system using mobile geographical information system technology

Abstract

The latest Mobile GIS technology is probable to manage the spatial components of daily business project, in the corporate database, and to apply proper geographic analysis efficiently in a desktop-focused application. This technology uses wireless internet for transferring process of spatial data from server to Mobile GIS or vice versa. However, the problem in wireless Internet is system bottlenecks that can slow down in the process of transferring data. One of the reasons why system bottlenecks could happen in this situation is because the spatial data is too large. The database design therefore is the most important part that must be considered. Database systems are now expected to be self-managing, self healing, and always-up. Another parts which also contribute in this problem are network, application server and web server (Kwan & Shi, 2002).
