The Paradise project is attempting to apply the technology developed as part of the SHORE and Gamma projects (Gamma is a parallel relational database system developed at the University of Wisconsin) to the task of storing and manipulating geographic data sets. Currently, many geographic information systems (GIS) use relational database systems to hold their data. While such systems are excellent for managing business data they are a poor match for the modeling needs of a GIS which must be capable of storing and manipulating much more complex objects such as polygons and polylines. Instead, Paradise employs an object-oriented data model, providing a much better match to the type needs of a GIS. Another significant difference from current GIS systems is that Paradise employs parallelism to facilitate executing and processing large data sets such as satellite images. The target hardware platform for the project is a cluster of 64 Sparc 20s connected with ATM.
