Wouldn't it be great if your HR folks only had to put in HR-SQL.mydomain.com for the database connection in their reports? They wouldn't have to remember it was on server Nile and they certainly wouldn't have to change their reports if you migrated their database from the Nile server to the server named Danube. In DNS there are two easy ways to do this.

A lot of people are storing large quantities of e-mail addresses in their systems. Since a large percentage of any system's user base is going to be supplying e-mail addresses from a few of the vastly popular providers (such as GMail and Hotmail), we are storing the "@gmail.com" and "@hotmail.com" parts of those addresses on disk over and over and over again.

When you are inserting, updating, or deleting records from a table, SQL Server keeps track of the records that are changed in two different pseudo tables: INSERTED, and DELETED. These tables are normally used in DML triggers.
