The purpose of this assignment is to alter and apply the trigger code to the Person.Person table in the Adventure Works database.

First, amend the trigger code (below) to fire correctly on the "Person.Person" table. Next, apply the trigger code provided below to the "Person.Person" table to track the number of modifications of data for the table. Check that the trigger worked by updating four records in the "Person.Person" table. Create a Word document which includes the altered trigger code, result table, and a screenshot of the fired trigger results.

• Add the "Title" 'Mr.' to 'Ken J Snchez'
• Add the "MiddleName" 'Timothy' to 'Michael Raheem'
• Add the "Title" 'Ms.' and change the "MiddleName" to 'Heather' for 'Samantha H Smith'
• Add the "Title" 'Mrs.' and change the "LastName" to 'Thompson' for 'Lori K Penor'
