Hi

I have a Use Case where I store an Account Tree in the database. Each =
Account Node points to its parent and I can resolve the tree using =
several database  queries by getting the account then its parent then =
its parents parent, I guess you get the idea!

We store data as attributes in these account objects and inheritance is =
used to easily propogate attributes down the account tree and override =
them at each node as required.

I've just been reading the wiki and seen a nice feature where I can emit =
index entries with foreign id's which is great if I already know them in =
the doc my map function is working on however I would prefer to just =
reference my parent and then *follow* that link to get the parent doc =
and retrieve it's parent id from there.

So I guess what I'm trying to ask for here is whether I can retrieve =
another  document from the database, by id, from within the map function =
in a view?
I can see lots of other places in our design where this could be really =
useful especially for validation of referenced id's within documents.

Thanks

John=
