What do you think about Hibernate? It apparently gives one the best of both
worlds (OO and relational).

http://www.hibernate.org/

>From the site:

Powerful object-oriented query language
-----------------------------------------
Queries expressed in a familiar-looking SQL-like language
Table joins expressed as property paths
Support for SQL functions and operators
Support for SQL aggregate functions sum, avg, min, max, count
Support for left|right outer join, full join
Support for group by, having and order by
Support for subqueries (on databases with subselects)
Queries may return tuples of objects or scalar values (projection)
Support for returning arbitrary data objects via the select new construct
Dynamic fetch profiles using the fetch keyword

Full support for polymorphic queries
------------------------------------
Queries may specify any abstract superclass or interface; from
java.lang.Object will return all persistent objects, for example.

New Criteria queries
---------------------
Alternative object-oriented "query by criteria" API.
full support for association navigation
runtime fetch profiles (dynamic outer join fetching)
extensible Criterion framework
powerful query by Example API

Native SQL queries
--------------------
Queries may be expressed in the native SQL dialect of your database.
