GeoCache

Lionel Savary, Georges Gardarin, Karine Zeitouni
2007 International Journal of Data Warehousing and Mining  
Depending on the size of the target geographical data and the number and complexity of operators in a query, the processing time may quickly become prohibitive.  ...  To optimize spatial queries over GML encoded data, this chapter introduces a novel cache-based architecture. A new cache replacement policy is then proposed.  ...  The spatial region content contains non-redundant spatial data of geographical query results, whereas the non-spatial region content contains non-spatial data of geographical query results.  ...

Hair-Oriented Data Model for Spatio-Temporal Data Mining

A. Madraky, Z. A. Othman, A. R. Hamdan
2015 International Review on Computers and Software (IRECOS)  
Traditional method to mining the spatio-temporal data is the fact that the data is stored in data warehouse in un-normalization form as union of spatial and temporal data know as tabular data warehouse  ...  Spatio-temporal data are complex in terms of number of attributes for spatial and temporal values, and the data are changing towards time.  ...  The authors appreciate the constructive comments of the anonymous reviewers, which has contributed to the improvement of this paper.  ...

BCAS: a web-enabled and GIS-based decision support system for the diagnosis and treatment of breast cancer

Guisseppi A. Forgionne, Aryya Gangopadhyay, Monica Adya, Joseph K. Tan
2001 International Journal of Healthcare Technology and Management  
For decades, geographical variations in cancer rates have been observed but the precise determinants of such geographic differences in breast cancer development are unclear.  ...  Applications of these models, however, require that the data be assembled from a variety of sources, converted into the statistical models' parameters and delivered effectively to researchers and policy  ...  The clients will generate and view reports and graphs of data stored in the MDDB server, which in turn derives the raw data from the data warehouse located at the DB server.  ...
