o A database user $($or role$)$ is a user $($or role$)$ to which the system administrator can assign database privileges. An application user $($or role$)$ is a user $($or role$)$ created and recognized by an application and cannot be directly assigned database roles or privileges. In multi$-$tier environments, an authenticated application user must eventually be mapped to a database user or to a database role in order to access database objects. Read "Considerations for Using Application$-$Based Security" and discuss how a database user can be mapped to application user$($s$)/$role$($s$).$ You can describe the consequences on the security of the whole system, its flexibility and performance $($using connection pools$).$
