Re: Data Dictionary

I wouldn't use that. Here's from the help:

The Create Data Dictionary (CRTDTADCT) command creates a data
dictionary.  A data dictionary must be created before the user can
use the Interactive Data Definition Utility (IDDU) to describe and
create database files.  The user can create a data dictionary with
IDDU or with the CRTDTADCT command. More information is in the IDDU
Use book, SC41-5704.

IDDU? Not in this century. Here's from Wikipedia:

A data dictionary is a set of metadata that contains definitions and
representations of data elements. Within the context of a DBMS, a data
dictionary is a read-only set of tables and views. The data dictionary
is database in its own dictionary. Amongst other things, a data
dictionary holds the following information:

   * Precise definition of data elements
   * Usernames, roles and privileges
   * Schema objects
   * Integrity constraints
   * Stored procedures and triggers
   * General database structure
   * Space allocations

So it's more than a Field Reference File, though that would be a
start. It's basically documentation that you want, right?

HI,
  We have new file layouts to use in our EDI process and I have been told to 
create them, along with a Data Dictionary.

  I have never created one before and only used one very very briefly many 
years ago.

  I did a search in the archives but did not find much.

  As I am stumbling along on the Create Data Dict. command, I would love to see 
any examples of how to set one up.

  THe data is EDI PO that is coming to us in 6 separate files from a 3rd party 
VAN.

  They are calling these flat files. The fields, are all alpha.

  Do I enter all of the potential fields into the Data Dictionary? Or only the 
unique fields that will be referenced?

  In what ways are the Data Dictionary different from a Field Ref. file?

  Any and all help would be tremendously appreciated.
  Thanks,
  Mike
