Hello !
Beginner's question:
What ist the easiest way to store and save objects in a file generated
by a C++ program, by using the "standard C++ library" and/or "Standard
Template Library ( STL )" ?
So I would like to generate some objects ( of different classes ) with a
C++ program and would like to make it permanent / persistent, so that

Hello all,
I am developing an interface system for an application I was written. This
interface will connect to other system to share information. I would like
to use
xml and xsl to generically describe each interface. The trouble I am having
is that it seem that if you export in xml by table then it is impossible to
combine the xml tables files back together in a hierarchical fashion. I can
do it programmatically but I would like to...

Hello,
I'm trying to understand how to map hierarchical XML data to relational
database tables, but I seem to be missing something. I'm not a database
expert, but I know the basics. XML seems so much more intuitive to me,
though.
Anyway, let me make up an example: Say we have an address book, in XML
format, that is to be uploaded by a customer and then mapped into relational
database tables. I would start by creating an XML Schema...

Hi,
I have a very simple question.
In what cases are relational databases necessary?
Are they really necessary in cases where only a
single type of query is to be performed based on one unique
field or can we just put all fields together in a single database
and just access them through that unique field?

Hello,
I need to take a set of input tables and create an XML output file. The
format of the XML output must be user-definable and must be intuitive
enough for non-techies to use.
input table(s) + SomeSchemaDefinition ==XML file
I have seen examples of XML file generation with fixed scope. For
example, if input table (called customer) is as follows:

Hi,
I am working on a program to archive data to disk.
At what point is it best to use a relational database like MySQL as
the backend instead of a C program alone?
Thanks to any and all replies.

I started playing with python a few weeks ago after a number of years
of perl programming and I can say that my first impression is,
unsurprisingly, quite positive. ;)
The reason I am writing here is that I can't seem to figure out how to
save/restore python objects into a relational database. The way I
used to do it in perl was to 'freeze' the object before storing it
into the database and 'thaw' it before restoring it. (For those not...

I have made a simple python module to handle SQL databases:
https://fedorahosted.org/pySQLFace/wiki
Its goal to separate relational database stuff (SQL) from algorythmic
code (python). A SQLFace is a facade initialized with a configuration
file (XML). It provides callable command objects for each sql query.
The call substitutes template variables with its parameters, and
returns the result of the query.
I would like to get some opinions...

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...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...
