Does anyone have a link(s) to a good article on how to map associations between objects as is pertains to communicating with the database? For example An employee has an office which to my way of thinking would equate to two objects employee and office but the database would have three tables employee, office, and a table called workstations that would be what offices are assigned to each employee. Most of the articles I've found are dealing with how to use nhibernate, llgen, etc... or deal with it in an abstract example with no implementation details. Any help would be appreciated
