I am going to use a contrived example: one headquarter has one-or-many contacts. A contact can only belong to one headquarter.

TableName = Headquarter

Column 0 = Id : Guid [PK]
Column 1 = Name : nvarchar(100)
Column 2 = IsAnotherAttribute: bool

TableName = ContactInformation

Column 0 = Id : Guid [PK]
Column 1 = HeadquarterId: Guid [FK]
Column 2 = AddressLine1
COlumn 3 = AddressLine2
Column 4 = AddressLine3

I would like some help setting the table primary keys and foreign keys here?
How does the above look?
Should I use a composite key for ContactInformation on [Column 0 and Column1]?
Is it ok to use surrogate key all of the time?
