[AccessD] exporting one to many tables into flat file

[Rocky Smolin]

1toM is hard to represent in a flat file.  The many should, in theory be
strung out in columns but the problem is how many columns to allow for? For
a CSV file the problem is not as great because you can just create a string
of the primary fields, and keep on concatenating the Many values (the
Organizations) to the end of the string, separated by commas. You should end
up with a nice CSV file with the records each containing a different number
of fields.  

Which of course, means on the import, you need to parse the string and
extract the n number of organizations.  Since it's a CRM app with , I
assume, some kind of import function that may be problematical since an
import function typically wants to see a consistent number of fields in an
import file.

If the CRM app is based on a database into which you can push data then a
stand-alone importer would work.  But, of course, at that point you could
just push the data right from the MDB into the CRM database.  Is that an
option?

If, however, you need to use the CRM imported, and the importer needs a
consistent record with the same number of fields in the same place, , then I
think your solution is to create an export record with one Organization per
record.  Would that work?

I have a project where I need to export some of the data from a relational
database (MDB) to a comma delimited file for import into web based CRM
program which utilizes a flat file. The client data will now have one row
with a "tag" field for each organization that it is related to (some of
these clients are linked to hundreds of organizations). I'm l looking for
suggestions on how best to approach this:

 

Client 1toM > Phone > Mto1 PhoneType

Client 1toM > ClientOrg <Mto1 Organization

 

Thanks in advance,

John B
