I took quite a number of database classes in school, and they all dealt with relational databases. However, we covered OO databases, and from what I remember they are completely different from relational. For example, 
select * from emps a, payroll b
where a.empid = b.empid

would not work in an OO database, because this is using relational logic. I might be wrong here, because I've never worked with an OO database.
Also, we talked about the fact that OO databases are still very obscure, and in the opinion of my professors, there is a good reason they are. The idea behind them pretty much sucks. Somethimes I think people go a little overboard with the beauty of OO abstraction. Yes its cool, but there are lots of cases where OO is too much work and/or it's inefficient. That's why Perl is such a popular language, because its designer recognized that most people hate being constrained to a difficult and obtuse function, especially when it's inefficient.
