You have two database servers SEMPand SACCT. The database in the SEMPserver maintains the employee information and the database in the SACCTserver maintains the accounts payable information.
The employees submit the expense reports to the accounts payable department. A user of the accounts payable database wants to extract the employee information from the database in the SEMPserver for cross-verification.
Which schema object enables the user to access the information from the remote database?
