[Friday] General question on OO database design
Is there a standard spec on OO database modeling? Is there a project that
facilitates OO database access layer in Commons? It would be so good if we can
do something like getPerson(id) to a database directly instead of structured SQL
queries.
Thanks!

AFAIK there is no standard specification for mapping objects and object
graphs to relational database tables. However there are many
Object-to-relational mapping frameworks which will do it for you.
ObJectRelationalBridge (OJB) is one, http://db.apache.org/ojb/.
