发明名称 System and method of optimizing database queries in two or more dimensions
摘要 A method and system for storing and retrieving spatial data objects from a spatial database is discussed. The system stores multi-dimensional objects within the database by determining their position in a multi-tiered coordinate system. One each object has been assigned to a particular coordinate, the object is further assigned to one of many overlapping sections within the coordinate system. Each object is assigned to a particular section of the coordinate system depending on its overall size and position.
