    16 These arrangement are possible in Oracle as well, but they implies the storage of multiple SDO_GEORASTER objects linked to as many SDO_RASTER table. A complex coverage can lead to hundreds of table in the database. With WKT Raster you can store a similar raster arrangement into a unique table.
