Evaluation and demonstration of array database management systems using national geospatial data (RDA-ArrayDB)
In the project RDA-Array DB, we will evaluate two array database management systems (DBMSs) using national geospatial data. The aim is also to demonstrate, how those systems store and retrieve multidimensional geospatial information, and how they carry out simple geospatial analysis tasks.
