Hello,
I have posted a question related to this problem before but I never got the full understanding of the concept. I would really appreciate if someone could help me, my deadline for the design of the project is in 2 days and I'm still having doubts :(
The system I'm developing is a VB/ASP.NET web application connected to a MS SQL Server Express.
The requirement is to be able to view a report that shows actions performed on all the tables in the database.
For example, I have an Item table. Whenever an Item is inserted in the table, in the report, I want the user to be able to see the user Id of the person who added the Item + action + date time.
I have many other tables such as Department, Transaction, Item Type which also I want to keep track of the actions performed on them.
I know that I have to add a History table that will store all this, but the question is, should I add a table for each entity (Department History, Transaction History, Item Type History) ?
I've read this article on how to approach this problem using Triggers:
http://www.4guysfromro lla.com/webtech/091901-1.shtml#postadl ink
But I'm still not sure of the number of tables that should be added.
Please help :)
Thanks

Hi
I'm developing a database with access and I was ask to include in the report
the date of issue. But if the date of issue was change It should be
included in the footnote area the issue date that was originally was written
and by who. And as if it was changed several times it should be included as
well.
How can I include this historical tracking in the report?

I am writing some software that, among other things, needs to track

deleted from a mySQL table ??

I'm working on a project that will track a great deal of data forindividuals and will keep track of users for a very long time (5- 10) years. I'm looking for options as far as tracking anddisplaying changes to the data. Any suggestions for both the UIand the Data Storage aspects of tracking long term changes todata would be helpful.

Maybe this feature is already out there.
I guess you could write triggers to do some of this.
Often when designing a database I add a start_date and end_date column
to the table. The start_date is when the record was created and the
end_date is when the record expired. For UPDATES, I populate the
end_date and INSERT a new record. This allows you to track changes
though out time.
I do this so often I thought it would be a good idea for...

One of my systems grew exponentially - from 13mb to 43mb - after adding some
10 temp tables (with no data), a new form, and about a thousand lines of

good bit of code overall.
But 43mb is totally unreasonble. I can't figure out where the problem is
occurring. It was fine for a long time. I even created a new file and

Hi,
I have a question regarding best practices in database design. In a
relational database, is it wise/necessary to sometimes create tables
that are not related to other tables through a foreign Key
relationship or does this always indicate some sort of underlying
design flaw. Something that requires a re evaluation of the problem
domain?
The reason I ask is because in our application, the user can perform x

How do you maintain foreign key references with this approach?
eg, you have these 4 tables:

Hello,
I have setup an Access Database which about 7 people can enter data
into. We have had a few problems where a 'fairy' has mysteriously been
changing data in the table that they're not supposed to. I was
wondering if it was possible to find out which user is responsible for
making these changes. The database is not password protected or
anything.
Kind regards,

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...
