Object-Relational Databases introduce new
features which allow manipulating objects in databases. At
present, many DBMS offer resources to manipulate objects in
database, but most application developers just map class to
relations tables, failing to exploit the O-R model strength. The
lack of tools that aid the database project contributes to this
situation. This work presents O-ODM (Object-Object Database
Mapping), a persistent framework that maps objects from OO
applications to database objects. Persistent Frameworks have
been used to aid developers, managing all access to DBMS. This
kind of tool allows developers to persist objects without solid
knowledge about DBMSs and specific languages, improving the
developers' productivity, mainly when a different DBMS is used.
The results of some experiments using O-ODM are shown
