Oracle dump (.dmp) file format

I am wondering about how is the internal format of a .dmp file (dump file, or backup and restoration file) used by Oracle RBMS.

Does it follow any standard? Is it optimized in any way?

Thanks.

Edited:

Oracle version: 11g

  • Does it follow any standard.

    Yes - the one that Oracle defined for their export format.

    It it optimized in any way

    You can compress the data, if that's what you mean.
    See the manual for details: http://docs.oracle.com/cd/E11882_01/server.112/e22490/dp_export.htm#BABCAJHC
