Several months ago I started a thread with the title "What is/is not
considered to be good OO programming" which started a long and
interesting discussion.
I have condensed the arguments into a single article which can be
viewed at

I fully expect this to be the start of another flame war, so sharpen
your knives and get stuck in!

I'm looking for people's opinions and feedback regarding the design of the
application tier, and how to best logically separate out the Data Access
from the Business Object's. Per the Microsoft prescriptive architecture
documents, they recommend creating a completely separate logical Data Access
Tier of components. Then creating a separate tier of Business Objects that
consume them.
My first question is...what does this actually buy you...

Hi,
I'm working with the ObjectDatasource and the application is getting more
and more chatty. Is there a way I could make the ObjectDatasource support
multiple DataTables that could be retrieved as one Dataset? I'm wondering
how others out there work with ObjectDatasource?
The only option I now see to get this fixed is to manually make the call to
the Web services, retrieve the Dataset and assign the datatable to the
controls (Or can...

Hopefully this will make some sense.. I have a database that has around 50
tables - I thought about putting each table in a class and the data
connection in a class then I could manage the (tables) classes with one data
connection. The business logic would open the database class then whatever
table class is needed, the close the tables and the connection.
The other way would be to open a data connection in each class. Since

You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it.

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
