Answer / krithiga hari
Generation Data Groups or GDGs are a group of data sets
which are related to each other chronologically and
functionally.
Generation 0 references the current generation.
Generation -1 references the generation just before the
current generation.
Generation +1 references the generation just after the
current generation.
MODELDSCB is a model prototype which contains the
specification for the DCB subparameters for all data sets
that will belong to the GDG. Each time a data set belonging
to that GDG is created, it will use the DCB subparameters
specified in the model prototype.

GDG stands for generation data group. It is a dataset with
versions that can be referenced absolutely or relatively. It
is defined by an IDCAMS define generation datagroup execution.

Answer / guest
GDG is Generation data groups to maintain versions of a
file.It can be daily, monthly or early. This will be
created using IDCAMS with no of version of the GDG.
MODELDSCB is the one we can use some other GDG as a model
to create a new GDG.
