Noob question - what do the colour flags in Database Expert signify? 2

[DilbertAsok]

As per the picture - what do the yellow, red, blue, yellow/red, etc colours mean within the different tables mean?

Presumably something to do with the linking options?

 

[hilfy]

The color flags identify fields that are in an index - different colors for different indexes.

It's always better to link on fields that are in the same index if possible because it will speed up the query.
