Comparing Between 2 schema

We can compare two schema with the help  of the below queries:

 compare the two users in terms of tables

SELECT TABLE_NAME FROM ALL_TABLES
WHERE TABLE_NAME NOT IN
(SELECT TABLE_NAME FROM ALL_TABLES WHERE OWNER='EMP1')
AND OWNER='EMP2';

compare the two users in terms of objects 

SELECT OBJECT_NAME||' '||OBJECT_TYPE FROM ALL_OBJECTS
WHERE OBJECT_NAME NOT IN
(SELECT OBJECT_NAME FROM ALL_OBJECTS WHERE OWNER='EMP1')
AND OWNER='EMP2';

when we transfer data from one schema to other schema and we want to verify them after successful transfer.
