A large company with a few database administrators $($DBAs$)$ will find it hard to cater to the needs of every end user when trying to provide the right data to the right people, at the right time, and in the right format. Using the enterprise tools and already established Intranet networks, how can DBAs make it possible for the end users to gain more access to relevant data for their jobs?

a$.$

Change the distributed database model to a more local or central system.

b$.$

Certify each end user to be a DBA.

c$.$

Build a web front end with a friendly user interface.

d$.$

Set daily backups to protect data from loss.
