Hello,
I have very difficult task , I must convert some sample database in Oracle to BerkeleyDB database. I am rookie in BerkeleyDB and I have no idea how to start and what to do, so please share your knowledge .

Regards

Berkely DB stores all data as key value pairs, so you will have to convert all your table columns as one comma/colon/etc. separated string and then store each table in a separate db file.
