You discover the following performance problems in the database. The performance of the application
queries against the
OrderDetail table is poor. The maintenance tasks against the database, including index defragmentation,
take a long time.
You need to resolve the performance problems without affecting the server performance.
What should you do?

A) Create an additional table named OrderDetailsHistory for data older than three months. Use the following Transact-SQL statement. CREATE TRIGGER trgMoveData ON OrderDetails AFTER INSERT AS INSERT INTO OrderDetailsHistory SELECT * FROM OrderDetails WHERE DATEDIFF( m,OrderDate,GETDATE ()) > 3

C) Create an additional table named OrderDetailsHistory for data older than three months. Partition the OrderDetails and OrderDetailsHistory tables in two parts by using the OrderDatecolumn. Create a SQL Server Agent job that runs every month and uses the ALTER TABLE...SWITCH Transact-SQL statement to move data that is older than three months to the OrderDetailsHistory table.
