Re: Data Dictionary

["Michael Ryan" <michaelrtr@xxxxxxxxx>]

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?
