Oracle
In Oracle, we use VARCHAR2 for JSON. PostgreSQL also supports the JSON data type. For more information about how to use JSON in PostgreSQL, visit https://www.postgresql.org/docs/11/functions-json.html.
Oracle can support geometric data via the SDO_GEOMETRY data type. This type allows you to define points, lines, and polygons but works a bit differently than MySQL. For more details, visit https://docs.oracle.com/en/database/oracle/oracle-database/18/sqlrf/Data-Types.html#GUID-022A5008-1E15-4AA4-938E-7FD75C594087.
XML: Oracle supports XML data type using XMLTYPE. XMLTYPE implicitly stores the data in a CLOB data type column. A CLOB data type stores large character data up to 2 GB in size.
