Too often, denormalization is suggested as the first thing to consider when tackling query performance problems. It is said to be a necessary compromise to be made when a rigorous logical design hits an inadequate database system. As the saying goes, “Normalize ‘til it hurts, then denormalize ‘til it works”.

When designing a database, we sometimes come across situations where there are multiple types of entities that we are modeling, but we'd like them to all have certain attributes or relations in common. Using "sub-type" tables is a simple way to implement table inheritance in SQL Server.
