THE PARSING OF GEOMETRY FIELD FOR ORACLE SPATIAL

Oracle Spatial is a module that manages the spatial data in oracle database and it uses SDO_GEOMETRY field to store spatial data and the advanced functions of oracle spatial, such as indexing and query based on the storage mechanism of the field. This paper parses the components of SDO_GEOMETRY field and presents the storage methods of points (including the compound point), lines (including the compound line) and polygons(including the compound polygon) in SDO_GEOMETRY field, which could be some references to those who want to access spatial data by programming.
