The Data Pump is a server based utility vs. the traditional
Export / Import which are client based utilities. The
Oracle Data Pump is not compatible with the Export / Import
functionality.

The Oracle Data Pump can also use NETWORK_LINK
functionality to move data and metadata from a remote
database without a dumpfile using the network technology
between the two databases.

Answer / kittu

Datapump has self tuning utilities where as in Exp/imp we need to specify the tuning parameters like buffer & record_length.

While doing datapump job data doesn't travel through the network, it will be done in server side only, so no data transformation through network

Answer / anonymous

We have parameters like parallel to assign number of workers in data pump, but not in exp/imp.
Also Data Pump uses stream pool of SGA.

Answer / rizwan

In traditional datapump exp/imp utility we can not stop the job when it's processing.
whereas in newly expdp/impdp utility we can stop and restart the job
for example, we are exporting the 5 mb size of table and,suppose we want to stop this job so it is possible in expdp but not through exp utility.
