Hi

I have a complex application that I'm working on splitting up a bit, I'm a little way through but wanted to ask a question. My middle-tier has around 25 data-objects so far, all linked to a main application object.

Now, what I want to know is if what I'm doing, is a good idea. Rather than create new instances of data-objects on the forms, I call a method in the (middle-tier) application object that returns a reference to the data-object, this way, if the object is updated by one form, it will always be reflected because it is a continuously running single instance.

Is this good practice? Or is it better to create objects freshly?

Thanks in advance
