What is role in DB2?

In DB2, a role is an object of database that group various privileges together and can be assigned to groups or user by GRANT statement.

In the context of DB2, a “role” refers to a database object that is used to group together a collection of privileges or permissions. Roles provide a way to simplify the management of permissions by allowing you to assign a set of privileges to a role and then grant that role to one or more users. This helps in managing permissions more efficiently, especially in situations where multiple users need the same set of privileges.

Roles can be used to simplify the assignment and maintenance of permissions, and they can be especially useful in large database environments where managing individual user permissions can become complex.

To summarize, a role in DB2 is a named collection of privileges that can be granted to users, simplifying the administration of permissions in a database.
