Testlet 1
Scenario 3
Application Information
You have two servers named SQL1 and SQL2. SQL1 has SQL Server 2012 Enterprise installed.
SQL2 has SQL Server 2008 Standard installed.
You have an application that is used to manage employees and office space. Users report that the application
has many errors and is very slow.
You are updating the application to resolve the issues. You plan to create a new database on SQL1 to support
the application. The script that you plan to use to create the tables for the new database is shown in Tables.sql.
The script that you plan to use to create the stored procedures for the new database is shown in
StoredProcedures.sql. The script that you plan to use to create the indexes for the new database is shown in
Indexes.sql. A database named DB2 resides on SQL2. DB2 has a table named EmployeeAudit that will audit
changes to a table named Employees.
A stored procedure named usp_UpdateEmployeeName will be executed only by other stored procedures. The
stored procedures executing usp_UpdateEmp!oyeeName will always handle transactions.
A stored procedure named usp_SelectEmployeesByName will be used to retrieve the names of employees.
Usp_SelectEmployeesByName can read uncommitted data. A stored procedure named
usp_GetFutureOfficeAssignments will be used to retrieve office assignments that will occur in the future.
