Loading, Transporting, and Validating Spatial Data
In the previous chapter, we introduced a new data type called SDO_GEOMETRY to store spatial data. This data type can store a variety of spatial objects: points (including those obtained by geocoding address strings), line strings, polygons, or more complex shapes. Points primarily represent the locations of application-specific entities such as businesses, customers, or suppliers. Line strings and polygons, on the other hand, represent the boundaries of geographical entities such as roads, cities, or states. In CAD/CAM-type applications, line strings and polygons can represent different entities such as the layouts of buildings, printed circuit boards, or shapes of different parts of an automobile.
