DB2 table vs Physical files

["Lokesh Gupta" <Lokesh.Gupta@xxxxxxxxxx>]

Hi,
I used to work with Physical Files (PF)  and this is first time when I may have 
to work
with DB2 tables. I need to pull data from As400 to windows environment (this 
could be
.net or Java) over ODBC and I have an option to use physical files or DB2 
tables. 
My question is (1) which option would be better for performance pov PF or DB2 
tables. 
I do not need to join lot of tables, it is just couple of tables and a simple 
query. 
I do not see any difference from windows side to access the data.

Secondly, Is there any data conversion involved (db2 or PF) as I am pulling 
data 
from AS400 to Windows, if yes, how will that affect the performance.


regards,
Lokesh
