Northwind Design Modification

[tbrogdon]

Just as an example, how would I modify Northwind if every order could
be made by multiple employees and I also needed to track how many
hours of a day those employees worked on a given order? In other
words there could be multiple employees listed in the orders table (by
line item for instance) and I also want to track how many hours of a
workday those employees spent to produce their input to any given
order.

Thanks,

Tim
