You have a database that is denormalized. Users make frequent changes to data in a primary table.
You need to ensure that users cannot change the tables directly, and that changes made to the primary table
also update any related tables.

a table-valued function

D.
the TRY_PARSE function

E.
a stored procedure

F.
the ISNULL function

Using an Indexed View would allow you to keep your base data in properly normalized tables and maintain
data-integrity while giving you the denormalized “view” of that data.
