We are working through the MM.NET 3.5 jump starts. I am doing the business objects exercise and trying to follow what it does.

In Step 6: Enhancing the Order Business Object we declare this.PrimaryKey = "OrderID", this in the Order.cs class constructor.

What if you are using non-clustered indexes with unique declaration in order control your primary keys, rather than clustered indexes. Pretty much all our data revolve around use of an institutional identifier (like soc sec nbr, but not), so I will NOT have a contiguous set of numbers, nor ability to control assignment of this number. Clustered indexes on this value would not be a good idea. Thus our initial data model using non-clustered indexes with unique.

How will the MM.NET framework work with this? Does this.PrimaryKey have to be a true clustered index?

Thanks,
Ron.
