NEBULA: A P2P Based Cooperative Spatial Database Prototype

摘要：

In order to integrate heterogeneous spatial data sources to enhance spatial data share and interoperation, the P2P computing technologies were introduced to implement a prototype system of cooperative spatial database named NEBULA. By dynamic and self-cooperative features derived from P2P computing, this cooperative spatial database prototype made individual spatial databases united to achieve users global spatial queries. Many P2P middleware technologies such as global resource directory, global query decomposing and sub-queries execution management were introduced to achieve the P2P spatial database system. Benefited from the P2P cooperative system, users can submit spatial queries in a global view regardless of where the spatial data store and how the spatial processing occurs. Lastly, a sample was also provided to show the entire workflow of the P2P spatial database prototype.
