Oracle Database Discussions

Hi,
I want to migarte Array data type of Postgresql to Oracle.
I have a table with 3 columns having array data type.
Can i go with Nested Tables?
If yes then, Is there any performance loss?

I have below table in postgre and i want to migrate it in Oracle.
CREATE TABLE EMP_DETAIL
2 ( "ID" Integer PRIMARY KEY,
3 "NAME" Text,
4 "DESCRIPTION" ARRAY,
5 "CITY_ALLOC" ARRAY,
6 "LANGUAGE" ARRAY
)
/

Please suggest the best Approach...

Thanks in advance.
