People usually start talking about SQL (or SQL based interfaces like
EOF) because they are very good ways of accessing large sets of data,
especially when you are looking at relational data, or complex queries.
A lot of thought has gone into the tools, and they are very good at
what they do.
If you are looking for a small set of data and can brute-force most of
the searches, then a lot of people will simply use objects, and then a
serialize method to write them to disk. Presto: little to no mapping
required. There are also smaller solutions out there such as SQLite
(
http://www.hwaci.com/sw/sqlite/) which are Public Domain (warning: it
does not enforce type at all). And some object stores (see
freshmeat.net) out there for a variety of languages.

This topic seems to come up consistently. I'm curious as to why EOF
or SQL Libraries are the first things to be discussed.
Is it because of Legacy databases that people want to connect to?
External reporting tools ? Interoperability ? I'm not sure that for a
new standalone or relatively small multiuser application that I would
like to have an unnecessary binding between my model objects and a
relational schema unless it buys me something significant.
Are there other viable options ? i.e. Object databases ? XML
databases ?
What about something like ZODB ?
