Trees or Tables? LDAP or RDBMS?

I believe
OpenDS will turn out to be a very popular project.
The team has been taking a soft-launch approach but they actually are already
in pretty good shape -
check the OpenDS tag for some earlier news.

Trey recently wrote a blog entry contrasting
LDAP with RMDBS.
In part it boils down to whether your application data is better modeled by
title="Hierarchical model">Trees or
title="Relational model">Tables.
Check out Trey's blog.
You may want to also check the
LDAP page at Wikipedia,
and the latest standard spec,
LDAPv3,
at
IETF

    I have yet to read the blog entry you mention, but having built trees in both RDBMS and LDAP, I would go for the RDBMS route any day. LDAP is a horrible place to store anything other than users/passwords and network login stuff. What a pain it was to actually walk the tree and even worse actually store information in it.
