Figure 3-6
This illustration describes subgroup inheritance of read/write access.
WESTERN_REGION is the parent group. Subordinate to that are three
subgroups: WR_SALES, WR_HUMAN_RESOURCES, and WR_FINANCE.
Subordinate to WR_FINANCE are two other subgroups: WR_ACCOUNTS_RECEIVABLE
and WR_ACCOUNTS_PAYABLE. If an administrator grants a user read
access to WESTERN_REGION, then the user has read access to all subgroups
of WESTERN_REGION. If the administrator grants the user write access
to the WR_FINANCE subgroup, then the user has write access to all subgroups
of WR_FINANCE.
