Answer to Question 1

In the context of database security, schema refers to the ownership of database objects. Users can be assigned to a schema much as they can be assigned to a role. Then permissions can be granted on the objects of the schema. The effect is much the same as using a role. In addition, schema can be assigned to roles, so that a role can contain both permissions and ownership of objects.

Answer to Question 2

Assigning permissions to individual users can be complex and hard to maintain. Roles allow you to create sets of related permissions that usually map to the ways various users work with the database. For example, a Human Resources role would contain all the permissions that those working in that department would need. Users can be dropped from or added to a role without needing to change the permissions.

Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.
