Secure object ownership by using Db2 roles

MoyenneNiveau 1Revue manuelledb2-zos

Description

Db2 roles can be used to control access to enterprise objects in a way that parallels the structure of the enterprise. It is recommended that you use roles to separate object ownership from individual users and manage context-specific access outside of user privileges. Assigning object ownership to a role prevents authorization IDs from obtaining implicit ownership privileges.
