Re: Question About DDMF

[Pat Barber <mboceanside@xxxxxxxxxxxxxxxx>]

DDM does not not care where or how a file is updated.

It's only purpose in life is to "point" where the file
in question is physically located.

The program opening the file doesn't know or care where
the file is located.

Bad system design using DDM files will create a LOT of system
overhead that can not be fixed.

A program running on development machine updating a file on
the production machine "might" or "might not" create heavy
traffic. That depends on (1) Line speed (2) number of updates

If you are attempting to read and write thousands or millions
of records on every update, the overhead will be incredible.

machine to read only? Gotta stop updating through DDMF.
