Which comes first? The database schema or class design?
I'm used to developing the database tables and fields based on the
functional requirements of an application, so it makes sense to me to model
my objects on the database schema, and their methods on the SQL/stored
procs. Most of what I read suggests starting with the class. Am I doing it
wrong?

The only correct answer here is probably: it depends.

Hello Mike,
I suppose it depends on many factors, there is no one golden question.
if it's data-centric app - then from schema;
I prefer to start from schema, because the DB is the bottom of your app and
changing the schema is more costly rather regenerating your classes for it.
the advantage of this is that u have the robust and powerfull db schema and
afterthat u can tune it on the conceptual level (with classes)

I had done reasearch on your query, It's Concluded that Class comes
first and then design is mapped with the Classs. so what u think, is
it OK!!!!!!!!!!!

I know both are pretty much the same and it comes down to personal choice.
But I have to make the choice for the team. Things so far that I am
considering
1. XML documentation in C# -- thats good.. not there in VB.net??
2. Some language features of VB.Net like Redim(makes it easier for
developers), but not good enough reason.
3. C# is in more like standard languages and key words used are more

INTRO
The phrase "decimal number" within a programming context is ambiguous. It could
refer to the decimal datatype or the related but separate concept of a generic
decimal number. "Decimal Number" sometimes serves to distinguish Base 10
numbers, eg "15", from Base 2 numbers, Eg "1111". At other times "Decimal
Number" serves to differentiate a number from an integer. For the rest of this
post I shall only use either...

Hello,
Are there any recommendations for which Windows python version to use? I'd like to
see a pros-and-cons description of each, given that different uses might dictate
different versions. The versions I know (and there are surely more) are:

I have Visual Studio Tools for Office (VSTO) and the SS 2005 Developer
that comes with it, all of which I can install on my local XP box.
1. Which one do I install first, VSTO or SS 2005 Developer??
2. Regardless of which one is installed first, what's the best way
after that to move or copy database objects like tables, queries,
reports, etc. from the XP/developer box to an SS 2005 Server??
Thank you, Tom

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,...
