[Phpgedview-talk] Places Hierarchy

[Nathan S. H. <nat...@uk...>]

I'm pretty new to phpgedview, but I have some experience with PHP and
MySQL. I may have some input to the way places are stored, but first I
have a few questions:

1) What's the difference between the pgv_places and pgv_placelocation
tables?
2) Does the hierarchical structure have to be stored using a parent_id
to link the child to it's parent?
    a) Is anyone aware of the nested sets model for storing hierarchies?
I believe there are several features that would make this implementation
of a hierarchy beneficial to PGV. I have some PHP code that I use for
doing hierarchy manipulations, e.g. adding/deleting nodes etc

Anyway, I'll await responses from those more in the known about PGV.

Cheers
Nathan
