hierarchyid SQL Server 2008

I want to store t开发者_如何学运维he regional information of a customer, for this, I will create the following tables

1. Country
2. State
3. District

But using hierarchyid in SQL Server 2008, I think I can store the information in a single table called Region. Am I right?

If Country, State and District share the same columns than a tree like structure would fit your needs. You could use hierarchyid or just a self referencing foreign key
