The answer to this will largely depend on your source(s).
Are these all databases?
One approach would be to build a webservice layer which
has specific methods to get data from each source and then
you can simply make webserive calls from your application.
Not sure if this helps but Good luck :-)

Currently we use a data adapter and a dataset for fetching
data from multiple data source.
Once we populate the data from each data source we
merge all datasets into a single dataset.
Hence if there are 50 data retrieved from 50 different
sources, we will have to have 50 adapters and datasets.
We need to know if there are any better approach to this
solution ?

Multiple database services and multiple versions on Red Hat Linux systems
The way it works is that we require a specific service script for each
database service (that is listening on each port). Each of these
services has a init script in /etc/init.d and a corresponding
configuration file in /etc/sysconfig. We use the 'chkconfig' utility to
decide if each of those services will be activated on boot or not (it
manipulates links under...

I have a people table of about 25 fields. The table is initially created each
year from 5 different sources. The records from each source are appended to the
people table. Any person may be in one or multiple sources. For those in
multiple sources, the data for a person may not be complete in any source. For
example, a person is in three sources; source#2 has the SSN and source#3 has the
membership#. For those people who are in multiple...

I am using Crystal Enterprise V9. I have a report that needs to have
multiple datasets as the datasource(s) on a single subreport (some
common lookup data I need to join to is stored in a seperate dataset).
The report is working fine with a single dataset as a datasource, but I
cannot seem to find any examples of multiple datasets as a datasource.
Is this possible?
ReportDocument.SetDatasource() seems to only take a single dataset,...

What is the best way to handle data in a multiple user environment? We
have forms that will allow users to add edit and delete data from a
table on SQL server. The data could be edited on multiple machines at
the same time. How do you keep the dataset constantly updated with
changes made to the data? I'm playing with just calling the fill method,
but it seems pretty unstable at times. Especially when deleting records,
they don't seem to...

Hi,
my existing web application(vb,asp) takes data from

Firstly, I have no problem with mail merging to Word, VB code for that
works perfectly.
On one mail merge I need to merge 15 fields of data that are from 3
seperate records.
The 3 records are all in the same table. If I use a control source that
is selecting the 3 records, all of the data is shown but spread over 3
pages in the mail merge, but needs to be listed together in one
paragraph.
Is there anyway of looping through the 3...

I am working on an N-tier application using following components:
1. Data Access Layer using DLINQ which consists of Data Context class

2. Business Logic Layer.

The problem is that I have to handle database transactions which can
span multiple tables. So where should I place the transaction code. I
think I should do it in BLL. But how do I control the transaction at...

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 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...
