I want to get up to date because I recently found out that BerkeleyDB is not an object database at all.
Maybe someone will describe the classification or at least send to a normal site, you can and bourgeois. There is one idea, with my heart I feel that the database for it needs an object one.
Thank you in advance.
One rumored good - DBMS Cache. The second is not very good experience - ZoDB (ZopeDB).
