Reasons for a 3-tier achitecture for the WEB?
(NOTE: I said, WEB, NOT WINDOWS.
DON'T shoot your mouth off if you don't understand the difference.)
I hear only one reason and that's to switch a database from SQL Server to
Oracle or DB2 or vice versa... and that's it.... And a lot of these
enterprises don't need it as they already know what database they are going
to use and they don't plan on switching in and out database in the first...

We've been developing a web site using 3-tier architecture for 18
months now.
There is a common layer that defines the classes - using XML schemas.
The data layer acts as a wrapper to 3 databases - SQL Server, Oracle
and AS400.
The business layer exposes web services which communicate with the
front end, ASP.Net. All 3 tiers are on different boxes. This works
well.
Now I am leading a team to build a winforms app. I need some advice as

I am developing a Windows Forms application in VB.NET that will use .NET
remoting to access the data tier classes.
A very simple way I have come up with is by creating typed (.xsd) datasets.
For example dsParts.xsd and including that in the data tier. I then will
create a class that looks like this
Public Class CPart
Inherits dsParts

I'm writing a winforms database application in C#. I've come across a lot of
stuff lately about "N-Tier" architecture.
Can anyone give me a simple explanation of N-Tier? The descriptions that
I've found online are chock full of lingo that I simply don't know. I need
the "N-Tier" for Dummies description. Talk to me like I'm in kindergarten.
Of course, I'm particularly interested in how N-Tier relates to creating a
winforms database...

My application uses a class to access to the dataBase, there are several
ones who are bussines objects (and uses the first one to work with the
database) and, finally, I have the interface objects.
Actually, I don't have any sql embebbed in the code so I'm working with
stores procedures in SQL Server.
Can I say that this is a n-tier (4 in this case) application?
Thank you very much.

Developing a new app and am trying to make this my first truly
OOP/3-Tier app. I understand the principles of the presentation,
business, and data layers. I do, however, have some questions on where
certain functionality should be placed and how some things should be
implemented.
Let's use a simple example such as an application to manage customer
records (customer_id, first_name, last_name). I'd have a Customer
business object with ID,...

Hi folks,
In an N-tier application, what is the possible values of N??? I'm not
kidding, I just interviewed with a programmer today, and he started the
"2-tier application" conversation. From then on, I heard about "5-tier
application" and then "7-tier application".... I do know what is a
3-tier application, but what about 2, 5, and 7??? Does 2-tier means a
"Client-Server" application model? What about 5 and 7???
Would you please...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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,...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
