Links and additional functionality

[Thorsten Hohage]

Hello,

so I'm a brave guy and reading through all the articles about  
different styles of links and I must admit I like them.

Especially when thinking about M:M-Links I missed a feature when  
reading through the docs, specifying a table for usage as "link"- 
table in background to store properties (in sense of OO properties  
and not of table properties if the new V3.5!) that need to be  
associated with this LINK, perhaps not a good description, but let me  
try to give some samples:

* Company <> Staff ( in this case a "Staff" member as a person can  
work for several companies): direct phone, or "business" email, room  
number, department, ...

* Contact (addressee) <> Document: the actual used address (for  
documentation if something changed), delivery type, personal  
greetings, ...

* Article (as Main article) <> Article (as Sub article): used  
quantity, quantity is absolute, print child, ...

When checking my current DBs ALL "main" or "business" required M:M- 
links have such extended properties, this may be, because I use this  
concept for a long time, but obviously they are "required".

Of course I can create a table and then search for a pair of keys,  
but then I didn't need to use any Valentina link logic at all.


regards
