I have the following classes:

public class InventoryItem 
{ 
     private Usage[] usages = new Usage[12]; 
     virtual public Usage[] Usages { get { return usages; }} 
     virtual public string Name{get;set;} 
} 

public class Usage 
{ 
     virtual public double Quantity{get;set;} 
     virtual public string SomethingElse{get;set;} 
}

I know that Usages.Length will always be 12. I think it would be best to store it in the DB like so:

Name nvarchar(64), 
Usage_Quantity_0 float, 
Usage_SomethingElse_0 nvarchar(16), 
Usage_Quantity_1 float, 
Usage_SomethingElse_1 nvarchar(16), 
... 
Usage_Quantity_11 float, 
Usage_SomethingElse_11 nvarchar(16),

How can I get this done?
