Yep. And Windows at least does the indexing for you if you put the tags in
the metadata of the file, letting you do searches and editing of metadata
entirely within the tools that come with the system. (Which can be annoying
sometimes if that's not what you're trying to search. :-)

I wasn't trying to argue that he should use a non-relational database. I was
simply saying that (contrary to what some of the younger generation might
know) relational databases are at the end of the evolutionary chain, not the
start.

Yes to all that. I don't even know of any existing hierarchical databases
*other* than UNIX-style file systems.
