First off this is a great reference for passing data between the Data Access
and Business Layers:

I use my own classes in the Business layer. I want to keep the Data Access
layer from requiring these classes so I tried passing a Datarow between the
layers and it seems to work good for me. Constructing the datarow in the

Hi all,
I'm currently designing an n-tier application and have some doubts about my
design.
I have created a Data Access layer which connects to the database (SQL
Server) and performs Select, update, delete and inserts. I use dataset
objects to pass data to and from the DAL.
In my GUI (windows forms), I use databinding to bind controls to a datatable

Hi all,
I'm designing my DAL layer(s) for our suite of applications and I'm
designing myself in circles, it's gotten to the point where each idea just
mixes me up more :)
We have 3 loosely related applications and I would like to use an assembly
for the DAL in each of them. I have thought of using a single assembly for
all of them with several different classes for providers/application
specific code, thought of a separate assembly...

I'm relatively new to ASP.NET 2.0 and am struggling with trying to find the
best naming convention for the BAL and DAL objects within my database. Does
anyone have any recommendations or best practices for naming my objects?
I currently have all my type classses simply called "JobSummaryClass" or
"JobDetailsClass". These classes simply contain the public properties and
the get/set functions for the object. Is this an appropriate naming...

Just wondering if it's standard practice to make DAL classes STATIC (in a
Windows Forms). Doing so would make sense to me because DAL methods are
typically called quite frequently - certainly the case for DAL "Helper"
classes - plus DAL objects/classes generally maintain no state. Seems like a
good case for STATIC classes to me.
It has been recommended to me to put the entire DAL, into a separate .DLL.
Is that standard practice too?

Hi all,
I was wondering about where this code should go.
Basically i have several tables in my database, when i add a row to a
particular table, i will need to also add other entries in other
tables.
I would consider this to be code that should be in the BOL? Am i right
in thinking that?

Hey
ASP.NET 2.0
I'm designing the DAL (Data Access Layer) of my web application. I want
every table to have a strongly typed object as wrapper arround the table. So
that for example if the DAL found 3 records in the table then it sends a
generic collection of 3 objects to the BLL (Business Logic Layer).
But here is the problem:

First, just in case, BLL = Business Logic Layer and DAL = Data Access
Layer.
I guess this is really a question about architecture. I believe there
are many architect here.
Software architecture is sorta new to me. I searched a little and did
find this:

I've finally gotton board with TDD (test driven development) and wow is it
effective! I went from sceptic to True Believer with my first effort.
My question: According to the various books and articles I have read about
TDD, a good unit test does not rely on the database or other such
external/environmental conditions. More generally, a good unit test is
atomic and makes as few assumptions about its runtime environment as
possible. But...

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...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
