What is a Generation Data Group (GDG)?


2 Answers

answered By Mswami   0  

A generation data group(GDG) is a group of related datasets, usually created in chronological order.  Using a generation data group to control the creation and retention of this type of dataset group greatly simplifies data management.  Before creating the first generation of a generation data group, two steps are required.  First, the generation data group base, which contains the rules for managing the group, is defined using AMS.  Second, a model must be created for the DCB parameters of the individual datasets to be created.

Generation Data Group is a group of chronologically or functionally related datasets. GDGs are processed periodically, often by adding a new generation, retaining previous generations, and sometimes discarding the oldest generation.
