For a search for all "Fred Green" material, wouldn't it be just a matter of printing:
(a) All of Fred Green's Events
(b) All of Fred Green's Characteristics (not discussed yet)
(c) All mentions of THIS Fred Green in anyone else's Event list
(d) All mentions of Fred Green in a global Event list

event, so I cannot see why you would want to link it to other people for later retrieval with the same wording - as if it was *their* event

representations of the instructions and trying to imagine what goes where - or wondering why we cannot get Access cannot do a particular thing.
So if a prototype in VB can be made to work, then it's just a matter of translating the VB written instructions into MS Access mouse clicks etc., and if that doesn't work, just use the slower VB code in partnership with Access.

*program* to do - not what you want a relational database to do. Some
or all of the work might be done more easily ~outside~ of a relational
database - or even outside of MS Access altogether. In some cases a
sophisticated relational database would work 100 times faster than VB
but hey, will genealogy people be complaining if they have to wait for
1000 milliseconds instead of waiting only 10 milliseconds for something to pop into view?

The question of where information should be stored depends on the program design, or whether there are both personal-use databases, as well as large industrial-strength databases. Smaller amounts of data could be stored in simple csv files, and large amounts in MS Access or separate csv files that are called when needed.

A much better version of the VB program has been uploaded to the Files section of this group's website. It's called "GENEVENTS2"
It can be used to store literally anything that one could ever imagine because users can add their own categories for Events, Facts or Relationships between people.
Any date system can be used, but if full automatic sorting is required for print-outs, then we need to use the YYYY,MM,DD format. If however some dates are not in the correct format (and order in a printout) then they can be simply re-positioned by Copy/Paste in the print-out panel.
If "Connected People" are required for event descriptions, then just click on their names and they will be automatically inserted.
If Sources of information are required for events etc, then they simply need to be entered with the event.
The program has a concise Help section in the Menu, so most questions will be answered there.
This latest version should make it easy for anyone to create a database with a SUITABLE 5.5 Gedcom and start seeing future potential or current weaknesses with the system.
