Research of spatial database based on spatial database engine
SPIE Proceedings, 2007With increasing demands of GIS applications system in a complex, integrated, and other areas, the spatial data are required rapid growth for the systems, and users are more and more on the demand spatial data. The method which traditional documents express spatial data is obviously unable to meet these needs.

Spatial database research has continued to advance greatly since three decades ago, addressing the growing data management and analysis needs of spatial applications. This research has produced a taxonomy of models for space, conceptual models, spatial query languages and query processing, spatial file organization and indexes, and spatial data mining.

Genericity in Spatial Databases
2000In 1980, Chandra and Harel investigated, in the context of the relational database model, which queries are “reasonable”. They characterized this class of queries by means of the concept of genericity, which has since taken a central position in the theory of computable queries.
