AFAIK Bitcoin version 0.8.1 uses Berkeley Database. How it uses this DB? Bitcoin not need install database from from oracle.com.I hear that new Bitcoin change to Google database, only Wallet stay with Berkeley DB.

Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

With BitcoinQt/bitcoind v0.8.x, the only BDB database is the wallet.dat.   All prior versions used BDB for the blockchain and other databases as well.  The client has statically linked everything so there is no installation of the database.

Beginning with v0.8.0 was LevelDB for the blockchain and everyrthing else other than wallet.dat

It would be nice if Bitcoin would move to BangDB, way better performance.

The one thing that never ever will be more important than performance is data-security Wink.
I don't say we should keep BDB either ^^...

BangDB isn't even open source (yet).
