What happens when DML and DDL changes impact change data?

Why is it important to track DDL in SQL Server?
Tracking changes is an essential SQL Server security task. Besides data change history, which includes DML operations (e.g. INSERT, UPDATE, and DELETE), tracking DDL changes in SQL Server, changes that affect database objects, is of high importance too. In this regard, various techniques can be used as a schema change auditing solution.
