Spatial and Geographic Databases Spatial databases store information related to spatial locations,and support efficient storage,indexing and querying of spatial data. Special purpose index structures are important for accessing spatial data,and for processing spatial join queries. Computer Aided Design(CAD)databases store design information about how objects are constructed E.g.:designs of buildings,aircraft, layouts of integrated-circuits Geographic databases store geographic information(e.g.,maps): often called geographic information systems or GIS 8 Database System Concepts,5th Ed. 24.8 @Silberschatz,Korth and SudarshanDatabase System Concepts, 5 24.8 ©Silberschatz, Korth and Sudarshan th Ed. 8 Spatial and Geographic Databases Spatial databases store information related to spatial locations, and support efficient storage, indexing and querying of spatial data.
