*Goal:*
The stated goal of this project is to "apply object-oriented and parallel database technology to the task of implementing a parallel GIS system capable of managing extremely large (multi-terabyte) data sets such as those that will be produced by the upcoming NASA EOSDIS project. [1]"

*Overview:*
Paradise is an extended object-relational database system: not only does it support the standard data types, but it also has "built-in support" for vector and raster data (i.e., raster, polygon, polyline, point, circle data types) [3].

*Features:*
   * Employs parallelism
   * All data types, both standard and GIS, are implemented as ADTs (in C++)
   * GIS data types implemented:
      * Vector data: Paradise includes point, polygon, polyline, swiss-cheese polygon, and circle ADTs
      * Raster data: Paradise supports 8-bit, 16-bit and 24-bit pixel sizes for raster data

*Concerns:*

*Evaluation:*
   * 

*Notes:*
   * Supports clipping of raster files to a polygon (vector file)
