Subj:   Re: Difference between ARCMAIN format and Universal format
 
From:   Dave Wellman

Hi,

The quick answer to your question is "chalk and cheese" (but that may only make sense to people from the UK!).

They are completely different.

An ARCMAIN backup file:

- is not intended to be read by anything other than ARCMAIN

- contains data in 'internal' format, i.e. how it is stored in the database, so a DATE field is in the backup file as a 4 byte integer

- retains compression

- (probably) retains encryption/encoding if you're using tools which do that to your data

- the dat ais transferred a block at a time rather than nominally row at a time


The 'universal format' basically contradicts all of the above.

Does that help?


Cheers,

Dave
