Does SF implement proper layered separation of concerns (SoC), such as the presentation (PLL), business (BLL), and data layers (DAL)?



Additionally, does the BLL use a Domain Model pattern with a separate Repository pattern for mapping entities to data access operations?



Also, does the PLL use an SoC pattern, such as MVC, MVP, or PM?



And finally, can I use dependency injection?



Thanks.

Hi Bill - welcome to the forum.



I was thinking of you this morning when I posted the tip in the winforms section about changing the parentclass of a control already on a form. I'm finding this subclassing in code stuff to be one of the most interesting and in a lot of ways most useful things I've run across in switching from Fox to .NET.



Just to expand a little on what I alluded to in that post : once you have created a whole bunch of business objects in your app you may decide you want to create your own baseBO subclass of the microfour business object. You just go into your current business objects and change one line of code. Whoooa.



Be sure to check out some of the great tutorial stuff Les Pinter has put up on his website.



Folks, Bill is coming in from a VFP/Maxframe background, so anybody who speaks Maxframe, you might want to give him tips that help the mental shift.

Hi Bill.

I don't speak Maxframe, I used to speak Codemine.

But anyway, welcome to the forum!

Hi Ivan,



Thanks! Never used Codemine but I did a couple projects with the original version (from the book) of CodeBook! The client (back in Pittsburgh) is still using the application!

Charles,



Drew had a terrific utility in Maxframe that allowed you to assign the parent class of any object on a form or class at any time. I got into the habit of just tossing labels, text boxes, etc on a new form and then changing them all to the project specific versions after they were all there. Made things really quick. (spoiled me also!)



This brings up a question that may be in the docs but I have just started, so bear with me. When building a new project in VFP I would always have "bills-company" class libraries that were subclasses of the Maxframe class libraries. Then I would subclass the "bills-company" classes for each project. I found this gave the the most flexibility but never seemed to impact performance negatively. Does this sound like a good plan for SF?
