Trees in Access

Does anyone know how to implement a tree structure in Access?

As I mentioned, I want to organize my keywords into a tree, so that (e.g.) the keyword "Location" has children such as "Europe", "Asia", etc., and "Europe" in turn has children "Ireland", "Great Britain", and so on. It seems that the obvious way to do this is to have each Keyword record have a "Parent" field, containing the ID of the parent keyword.

So far, so good. I want to construct a form which will show a keyword and a list of its children, and which will allow me to add more children to that list. Thus far, I haven't been able to get the latter to work. Any ideas? ("Use a different database program" will be considered only as a last resort....)

Thanks, but that won't do quite what I want. I want all of my keywords in the same list, and I want the tree(s) to be of arbitrary depth (so, for instance, under "USA" there might be "California", and under "California", "Los Angeles", and so on).

I think I've figured out a way around the problem; it's a little kludgy, but it ought to work.
