How to detect whether DB changes done

[WebEngel]

Hi,

I would like to detect whether any changes have been done to the DB?

A change is a rating change, category assignment and so on.  Not a change is (in my eyes) clicking around and viewing pictures or exporting them.

Motivation:
I have a PC and a Laptop and use Robocopy to copy the DB file between the machines.  Of course I plan to always use one instance as read only and do changes in the other one.  For example, I may be on a business trip with my laptop and then categorize pictures during long train rides.  Once back, I copy the DB to the desktop and will import pics there.  However, sometimes I forget whether I have changed something.  That's where I would like to it look up.

I have tried the log file and did find passages where I changed ratings or categories.  But I found the passages impossible to search with an editor.

Any idea?

Any other recommendations for my workflow?

Thanks,
Martin
