On Querying In Distributed Spatial Object Databases
Orlando Karam
There is a lot of interest in Geographical Information Systems. They require spatial data types. The complex nature of spatial data makes the Object Oriented approach to modeling the more appropriate for them. So, for databases that contain spatial data, an object oriented database is better suited.
Also, spatial data presents special opportunities and challenges for distribution. Spatial databases for GISs are usually very large. Also, the data is geographically distributed already, so it is more natural to distribute it.
There has been a lot of work on querying in OO databases. Spatial data, however presents special characteristics that ask for a somewhat different approach. Distribution, of course, adds more difficulties to the query process.
In this paper we will discuss some of the issues that affect querying in each of the areas (distributed, spatial, object oriented) and its intersection. Some experiences will also be presented.
