Moving towards Real Business Object Management
If you extrapolate the ideas in the preceding section, you might start to think "Why couldn't the manager perform the actual data base updates and deletes as well?"
If the instance list manager #EMPMNGR has methods like UpdateListDetails and DeleteListDetails that work on the employees' in the instance list, why couldn't it have methods named UpdateEmployee and DeleteEmployee that updated or deleted the actual database rows in a centralized way, and then automatically reflected the change into the instance list as well?
Indeed it could,but that's getting into the area of true business objects managers, which is a bit beyond the scope of this document.
